Velodyne Subwoofers Owners Thread

[betty boop]

watched a bit of "The incredibles" ch17, 23 and 27 actualy pretty much ended up watching the bits between these as well hehehe

Brought a big big smile to the face hehehe........actually at one point actually said "Holy **** !" can't remember when but giggled after saying that...all those solid thuds and sofa shaking explosions and thingd whizzing around etc the DD really adds so much to all this. Lookign at the spl meter the swings in dynamics in this movie is quite amazing.

There was also a bit of 2ch listening I was doing the other day. Oremi by the African singer Angelique Kidjo it was and listening to that, on track three I think it was, after a good bit of deep bass, I uttered out aloud "Bloody Hell !" hehehe my wife must think I'm going a bit cuckoo !. Anyways can only blame the DD for that if thats the case ! adding well to the enjoyment factor on 2ch as well this thing

It’s so nice when you have purchased a new toy and it keeps creating the wow factor for a long time after the purchase. If only others would take note and invest in some better quality equipment first up.

Subwoofers are relatively cheep when considered against the costs of the average setup and yet they are the mainstay of the operation IMO.

Now I must find all those posts of yours about not using a sub with 2ch.

hehehe thanks spearmint.

yes quality subs, spearmint, quality subs as your saying. I still say no point using a crap sub for music when your mains can do a better job of it and sound better on their own !

and the real problem is there are a lot of crap HT subs out there - jsut for boom and for fun factor for movies and probably add little to a good pair of mains for music.

anyways such a personal taste thing this, I'd suggest to anyone go with whatever sounds better. For me now yes with this sub yes it does add to the experience.

I was just funning with you…

And yes there is no reason a sub cannot be good for both HT & 2ch, and as you say whatever method sounds the best to the individual for 2ch is the way to go.

hehehe I should have added, your quite right too in regards the cost of ownership with somethign like this.

Like speakers the DD should last me a fair old while I'm thinking. And even with my thor, though 5-6 years old still sonically and visually as new, due to head of to my parents, should keep going I'm thinking no reason for another 4+years atleast.

Actually as an upgrade from my Velodyne CHT-10R, I'm going to call him Goliath.

David & Goliath

Goliath's new home.

Alebonau, it’s all your fault!! Well that’s what I’ve told The Lady Of the House!

Couple of weeks ago I borrowed a CHT-15R for 4 days and tested it to death, it didn’t perform too badly though there was a few factors - I'll call them niggles that led me to take it back. While I did have it in the same place that the DD-15 is now located, initially WAF was poor due to the increase in physical size of the Sub over the 10", though by the end of day 3 of having it, The Lady Of The House actually made comment that she no longer noticed it being bigger.

With that fact in mind and the DD-15 being marginally smaller than the CHT-15R, Oh and in a VERY high gloss finish (check that reflection of the arcatrave!), I knew WAF would be more positive than the initial reception when the CHT-15R came to visit. And thankfully so as I don't have a wedding photo in a frame to place on the DD-15.

Al, the link to the Sub Tests you provided us over at the AVTalk forums a few weeks ago that led me to the Velodyne and in particular the DD thread really had an influence in me looking at the DD-15.

Till then I was near sold on the SVS-PB12-Plus. Even though this particular sub was not tested over at AVTalk, and has the potential to go deeper, the facts, the PB12-Plus' physical size (for a 12" Sub), Velodyne's support with software, and reading the very positive experiences of others eventually sold me on the DD.

I'm off to run some cables!!

Don't think Ive used so many Smilies in one post though I'm just trying to reflect the current Cheshire Cat grin I'm wearing....

Well done - great sub choice (I've heard Al's) and I can see why you'd be grinning

Goes well with the polished baltic floors too - great contrast

Wow ! Wow ! Wow !

Congratulations ! Azz, welcome to our humble little DD club we got going here

hehehe well done indeed. Great to read you went for the DD yes why muck aroudn with anything else ! and have full right to be very happy about it too. Isn't it just so excellent, still in love with it, both its looks and sound

And I tell you those smiles will take quite a while to wipe off too ! and will keep coming back every time you listen to anythign with it

do post back how its going, though sounds like your over the moon already !

Hey, here's a conversation comparing DD's and Mike R. is nowhere to be seen! ....Coral, what have you done

BTW: Congrats Azz, I can assure you that the DD's have been on my hit list for a while now... I'm jealous

~laughs~ I can take it as good as I give!! Thanks guys for the words of praise. It really is an amazing piece of kit. I ran through a couple of HT clips on the DTS 4 demo disk with my receiver at -10 and the DD-15 on 17 (I think sub level is set to -5.5dB in the receiver settings) I never experienced Bass like it. It prompted a visit from my neighbour with another Ear to Ear Grin.. "So you got it huh? I brought over some beers...".

Now I had never really got off on the Canon Battle from M&C, (DTS Disc 9) never got off on it as I have never had to run around the lounge with 1/2 a packet of BluTac securing the pictures to the walls!!!!

Just finished watching Ch10 FTA News, seriously, its even a new listening experience. I do have a face ache.

Have had a bit of a play with the DD setup though far from happy. Playtime over the weekend. Al, I’ve the feeling we will be able to speak Whale by the end of setup??

Gents RE speaker layout, I officially believe I currently have THE Pig of all pigs of rooms when it comes to the ideal listening environment. My house was built circa 1934 and It's an example of 100% compromise when it comes to integration of HT & Audio into existing surroundings, and its one of the reasons I wanted to venture down the path of EQing my listening environment.

My walls are Timber (yes, real wood panels about 12mm thick) you should have herd the echo and brightness in the room before we got the curtains put in!

I posted a while back PICTURES OF MY LOUNGE and do admit to having had a fair bit of free reign in how things have been placed and setup.

In the "RH Rear" pic you will note some French Doors. These doors are actually the front door of the house!

They represent 1.68m of that particular 4.30m wall.

To the left of those doors is where the RH speaker is located.

Moving to the front wall where the speakers and TV are located, from the RH corner to the door located on the RHS of the picture "Front from Right" is a whole 54.5cm.

TV Cabinet is 103cm wide sitting on a piece of wall 1.12m wide (do you want to know how long it took me to find that cabinet?) then moving over to the left of the door where the sub and LH front are located, the remaining piece of wall is 89.5cm from the door to the LH front corner. By the way, those doors to the left and right of the TV are bedrooms.

Turning to the picture called "LH Rear", you will note an arch into the dining room(wall opposite the wall with the French Doors). That opening is 1.83m wide and 2.47m high. To the right of the arch you can just make a small amount of white skirting board. That wall is 98cm till it hits the front wall. Its where the LH Front and Sub are located.

Sitting on the lounge smack bang in front of the TV, the TV and centre channel are 3.1m away, the LH Front and Sub are 3.9m away, the RH front is 3.6m away.

I just re-read the above and its porridge - edited, and I did a quick SKETCH of the lounge.

Technically its not a big room - 4.30m x 4.14 x 3.1 ceilings.

Though that arch leading into the Dining Room can be considered the Black Hole of Death when trying to load a room with Bass Energy (those two words deserve capitals).

Believe me, as soon as the sun reaches its correct alignment (I feel its the end of this FY), it will be time to draw up plans and raise the house to build in underneath. I'll be bugging all those who have done their own HT room, and bouncing ideas about the place for mine!

If anyone has some "Quick Fixes" for placement correction of my current setup including the constraint that the lounge and TV wont/cannot be moved, feel free to share them with me. I'm all ears.

[betty boop]

Azz as I think you've probably explored, I don't think theres too many options wiht a room like that where door's and openings take up he bulk of three of the sides. .

With the setup you have now ideally it would be better to have the L&R speakers out a bit from the side walls - 0.5m away at least and experiment with the distance from the back wall might find need the same or more (say upto 1m) away from the back walls as well. Will aid the sounstage width and depth plus reduce bass boost of putting speakers in corners. Problem is the door openings about where the speakers or sub would go and don't think the wife would appreciate opening the door to find a speaker or sub right infront of her. With the sub ofcourse you have the luxury of moving that around and testing with the mic from the listening position to find the spot with the smoothest response. The beaut thing with the DD is you can just mute it and use this same tool wiht its test tone and response plot while moving the mains around to find the best spot for their bass response as well to aid integration.

Only other room orientation I can think off is flipping the room so TV ends up on the couch side and couch spread out across the door opening (not sure if thats an issue) where the TV is. You'd leave 1m or so for access into that side of the room. That will leave 1m from rear of cuch to the back wall - allowing room for rear surround possibilies along with side surrounds you have relocated to typical side of couch setting. Also will allow you to spread out the L&R speaker across the wall without the doors(where the couch currently is) plus sub might go say between TV and one of the mains. Just a suggestion and quite likely somethign you have explored anyhow and had to discount already due to aesthetics or WAF reasons keeping in mind a lounge room setup as it is. If you plonk the couches in their separate modules on the sketch people might be able ot make more suggestions.

either way sonically you now have a powerfull tool at hand with the DD to be able to move anything and instantly see the result with the response plot. Will be most usefull to find the best out what you have and with the SMS room Eq make adjustments to try get the best out of it as well.

Hi Azz ,You really do have a beautifull home and a nightmare as far as hi-fi installation goes.I tend to agree with Al that the only realistic way to resolve the problem would be to swap the tv cabinet and couch over or perhaps to put the single lounge chair where the cabinet is & the lounge down one side of the room.As things stand with the main speakers so far apart and in the room corners I would be very suprised if you get anything like the imaging that your speakers may be capable of not to mention a very uneven tonal balance which I doubt even state of the art eq could resolve.Given that the sub has those sophisticated eq abilities perhaps that could be put elswhere so that the lhs speaker can be moved out from the corner a bit.Try puting some sound adsorbers on the side wall beside the speakers to damp the sound being reflected from the wall.Sound adsorbers can be considered ugly but perhaps you could talk the wife into making something decorative to camoflage (however it's spelt) the appearance.

Ozcal & al, thanks for the replies...

As I mentioned, those French Doors are the front door. This room is the first room people see when you walk in my front door, and is obviously also a thoroughfare towards the rear of the house - kitchen, and certainly the deck outside.

In the "LH Rear" pic you can just make out the Deck past the tiled area thats the kitchen (Yup, shes not a big house!).

I think Im stuck with a pretty serious compromise at the moment as I don't want to block the thoroughfare, and that lounge is only 2 pieces - Chaise and a 2 seater with one arm. Take them apart and Im left with a 2 seater with 1 arm and a Chaise with the same.. ~shrugs~

Ive spent quite a few hours today playing with the DD, and dropping the crossover to 60Hz has helped soften the crossover issue Ive got, though certainly hasnt fixed it. It appears Ive got some sort of room null at 80Hz then a massive peak occuring at 120Hz..

Am yet to seriously play with the settings deep inside the Yamaha receivers setup. There are PEQ, Gain and Q settings that may help even it out a little.

~grins~ Oh well, off to cook dinner then I believe we are watching Day After Tomorrow.. :ph34r:

Hey Az ,it all comes down to priorities in the end and it is up to the individual to decide what those are.I completely understand your desire not to block the thoroughfares ,I had similar problems in my less than ideal lounge room just don't expect the amps onboard eq to be able to make up for your understandable layout comprimises.With the exception of devices like your sub most onboard eq devices are ,at this stage ,simply not powerful or accuarate enough to deal with such severe comprimises.Having said all that if your system lets you enjoy your music & movies then that's the most important thing.

Guys,

Would a DD-18 be the automatic best choice cost aside, or is there a standout model in the range that is the best compromise between speed and depth of bass? l am only interested in the sub for music.

Does the in room tuning really work as promoted as its one of the really appealing feautures of this sub range.

Cheers Mondie

The above "After" shot was achieved from a clear run in about 20 minutes. Your 1st 3-4 times is a learning curve, and it appears from others experiences that youre better off concentrating lowering (where possible) a slider than pushing them up add lib.

The dip I have at 100Hz I am about to put down to a room null. Want to do a bit more mucking about with raising the crossover to 130Hz on the receiver to see if I can get rid of it. I dont wish to run my crossover that high though as my mains are quite capable from 50Hz up. Just want to see if I can kill it.

Decision on the purchase of the 18" is very much reliant on room size. I have not seen the 18" in action, so will not pass judgement on its capabilities and how musical it is though I havent read a bad word about it.

Ive previously posted a drawing of my rooms dimensions, and the flow on room, and based on setup advice I have the sub set up on volume level 22 out of 99 AND have the LFE output from my AVR -6dB AND for channel levels - a further -3.5dB for the sub, AND the mains at +2dB.

Ive actually added a Y connector to the sub to help with the "Auto On" capabilites as the sub wasnt turning on with say a volume level that you watch TV with. The Y connector has fixed this.

These things have the potential to provide LOTS of volume at a very low THD! Quality and quantity!

Go and get yourself a coffee - actually go and put on a pot and settle down and read the trials and tribulations that the folk over at AVTalk in the UK have had with the DD series. Its a 26 page thread!!

April 2003 till now. Its well worth the read start to finish with several appearances from Bruce Hall the software designer from Velodyne.

Official Velodyne Digital Drive thread

In short, the DD-15 has been the most amazing and worthwhile piece of kit Ive EVER purchased.

Mondie, I'm not sure of your location, though I'm in Brisbane, and I know of atleast 1 DD-15 based in Melbourne - if you live up this way, I'm happy to have you over for a demo - music or otherwise.

A(still grinnin)

AVTalk Outdoor Ground Plain Testing

DD-15 +/-3dB: 14.1Hz -> >150Hz

Just being curious here Mondie, how are you going to integrate the sub with your 2ch? The reason I ask is Alebonau uses his sub to fill in the bottom of his mains with his mains running full range, Where as others cross their mains over at anywhere between 40~80Hz for 2ch.

Another item that I cannot comment about is the use of mono compared to stereo subs for 2ch duties. There are plenty of for and against arguments in each camp, but something worth considering when making your purchase.

Yes the EQ feature does work, but remember it is only a compromise and usually only measuring for one location. The addition of other people or just moving around the room will change the in-room response.

I usually EQ, and set the levels for the primary seating position, as you can spend oodles amount of time chasing audio nirvana.

Thanks for the pics, the before and after difference is amazing. My room is 5 x 6.5m so a DD015 is probably more than enough.

l live near Melbourne otherwise l would have taken you up on your offer My local HiFi pimp is trying to arrange to get his hands on a DD demo from Velodyne at the moment, in fact he is trying to get both the 15 and 18 so l can experiment with both. Hopefully he comes through

l am a sub virgin Spearmint l was thinking that l could run the sub from the second set of speaker outputs on my power amp . ie. high level input. l assume you could do that using the built in equalisation to smooth the bass? Would there be a better way of doing it?

That would work as would line levels and using a “Y” adaptor between you pre and amp.

The only problem with this method you have no control over the crossover point between your mains & sub, you could however use negative filters in the sub at the roll off of your mains.

thats a method REL use to feed their subs for 2ch - running a second set of speaker cables off the power amp to feed the sub the same signal as well.

another option to jsut use the sub to suplement the mains is what I've listed here

http://www.dtvforum.info/index.php?showtopic=34015

good luck with the DD demoes if you get the opportunity. I run one DD15 and your room seems a bit smaller than mine so would think it plenty. velodyne does have a section on their website involving pluggin in yoru room volume and they give you a guided as to a suitable sub. Apart from going 1 single 18 two 15s might be worth considering as well. Two 15s woudl be a lot more pricey than one 18 ofcourse, plus two subs would add a little in the complexity for set up I'd imagine though velodyne does provide a daisy chaining option.

The dip I have at 100Hz I am about to put down to a room null. Want to do a bit more mucking about with raising the crossover to 130Hz on the receiver to see if I can get rid of it. I dont wish to run my crossover that high though as my mains are quite capable from 50Hz up. Just want to see if I can kill it.

Decision on the purchase of the 18" is very much reliant on room size. I have not seen the 18" in action, so will not pass judgement on its capabilities and how musical it is though I havent read a bad word about it.

Ive previously posted a drawing of my rooms dimensions, and the flow on room, and based on setup advice I have the sub set up on volume level 22 out of 99 AND have the LFE output from my AVR -6dB AND for channel levels - a further -3.5dB for the sub, AND the mains at +2dB.

Ive actually added a Y connector to the sub to help with the "Auto On" capabilites as the sub wasnt turning on with say a volume level that you watch TV with. The Y connector has fixed this.

These things have the potential to provide LOTS of volume at a very low THD! Quality and quantity!

Go and get yourself a coffee - actually go and put on a pot and settle down and read the trials and tribulations that the folk over at AVTalk in the UK have had with the DD series. Its a 26 page thread!!

April 2003 till now. Its well worth the read start to finish with several appearances from Bruce Hall the software designer from Velodyne.

In short, the DD-15 has been the most amazing and worthwhile piece of kit Ive EVER purchased.

Mondie, I'm not sure of your location, though I'm in Brisbane, and I know of atleast 1 DD-15 based in Melbourne - if you live up this way, I'm happy to have you over for a demo - music or otherwise.

DD-15 +/-3dB: 14.1Hz -> >150Hz

DD-18 (Version 2.0 Software) +/-3dB: 21.0Hz -> >150Hz

DD-18 (Version 2.2.0 Software) +/-3dB: 15.1Hz -> >150Hz

you've done very well there Azz and without too much of hassle by the looks. Well done indeed ! and thats on top of all the highlighted room issues and all !

I seen you've gone for a pretty flat response rahter than a house curve or anything, gives me inspiration to give that a go on mine if gettign bored ! though still liking the punch with the added hump of the house curve in my response

and ps some very good links there. Would also add links to these coupel of mammoth threads going in avs
