Velodyne Subwoofers Owners Thread

Evening All.

Yes Al, at this stage, thought I'd opt for a flat response in setup, and then play with the Contour Freq and level to apply a curve for the particular mode/listening type I'm doing at the time. From all the reading Ive done over at AVTalk, not many have decided to apply a room curve.

For the benefit of others, each mode is fully adjustable, default there is a hump at 35Hz for HT, and one set at 50Hz for Rock/Pop. If you dont like 35Hz or 50Hz - you can put the hump where you like, There is also the ability to have the gain raised wiithin the preset for whatever mode..

Have added changing of the preset in the DD to my Harmony macros. Turn on the TV and the DD turns to movies, turn on the DVD and the harmony changes the DD to Action/Adventure. CD or Multi Channel it gets set to Pop/Rock (majority of my listening).

My previously discussed "dip" at 100Hz - I moved the mic to the SO's seat, and blow me down sho doesnt have it. Actually by default she has a better pre-eq graph than me!!

Shame Ive wrecked it for her..

Ive killed all the PEQ settings witihn the AVR and have gone for a 100% manual setup at the moment (manual size, crossover, distance and levels) and zero AVR EQ.

Havent listened to any music as yet though I noted tonight while watching FTA that voices sounded more crisp and perhaps maybe even a little "clicky"..

I guess with no EQ from the receiver, the uglies will start to rise from my fairly average speakers..

Mondie with your room size, and I assume concrete slab, and standard ceiling height, with the right material, and a modest volume level on a DD-15 - lets say 40/99, you will rattle teeth form your head and window glass from its frame..

Found this PIECE - its very "doof, doof" though great for finding resonations in the listening room and those joining it.....

Beware about playing that with PC speakers..

[Spearmint]

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

I believe Mondie only has a 2ch setup i.e. no HT AVR.

that is very true Azz with the DD can just start with the flat response and add humps with the various presets to see if like the effect for say movies or HT etc.

glad you've solved your peak probs ! hehehe and good to hear youve weaned yourself off the PEQ in the avr.

I believe Mondie only has a 2ch setup i.e. no HT AVR.

It makes the setup pretty conventional/straight forward then as no integration issues between 2ch/HT. With only a 2ch setup rel cater very well for this in their high end subs for this configuration via both high & low level. Or alternatively running a variable line level signal if available off the pre to the sub would be another option. Or full active xovers feeding the mains and sub as you are spearmint. Or utilising passive crossovers. Or xovers in the sub as you have indicated. Just comes down to what mondie wants to do in the end.

Correct, l am a basic user

Thanks for the advice Alebonau, l will look ito the Velo site and see what it recommends. The DD would only be needed if l went for the Ambience Ribbons.

12Hz anyone???

Extreme Woofer Test

Now how do I stop timber windows rattling in their tracts?

Piece of cake for the IB

You'll find the rattles of everything rattle at all different frequencies when excited. Some of my room items rattle at 12Hz, some at 16, some at 20 as an example.

Funnily enough I never had any of thesae when I had a conventional $1400 B&W 12" subwoofer (It was just not that "exciting")

Its a problem I happen to like

"exciting" is good.....

The opening scene of Gothica... Penelope Cruz - "He opened me up like a flower, and it felt GOOOOOD..."

[betty boop]

hehehe I found the DD had the power to move the front door on our place ! and thats when its talking whale during its sweeps ! hehehe a bit of felt tape helped that.

you can buy felt tape in rolls and swatches. can also buy lead/deadening tape from the likes of car audio shops - theres a product called brown bread and is sold in rolls. helps increase mass of things to stop them resonating.

[MrGadget]

Even my sub creates rattles with the windows. haven't bothered to do anything about it, although I should.

[Mjr69]

Wow! Look at how this thread has grown (I have only just stepped back in) and another two happy owners.

Congrats

For the last couple of years I've been running a DD15 and a HGS15 in my HT.

The reason for this being that with just the HS15 I found the bass to be a little directional and sought to eliminate this problem by adding a second sub and hence the DD15.

Last week I decided to try a DD18 and it simply blows the two 15" subs away.

The data sheet on this page is worth reading and apart from the hassle of finding a laptop with a serial port, the upgrade is very, very easy.

So the 18” is that much better than 2x 15”?

Does this mean you now have a DD18 in the mix?

[Azz123]

Quote from a dealer that is pretty knowledgable with the Velodyne's known as "Uncle Eric" on the AVTalk forums.

". As a ball park figure, double the power and SPL output will go up by some 3dB (if the driver and the rest of the sub can take it)

Going full circle. The DD-15 is quoted at 15Hz and the DD-18 at 14Hz. In truth, both the 15 and 18 will play 14Hz. The DD-18 will play it a little louder is all.

However, a pair of DD-15's will up the ante considerably against a single DD-18 and will (all things being equal) knock the single 18 into next week, EQ or not."

Sounds logical to me......

Discussion RE 1x18 or 2x15 start about 2/3 of the way down the page found HERE

THIS is supposed to be the "Ducks Guts" when it comes to Velodyne's best offering..

[Darrylp]

Yes, but I'm in the middle of a total speaker upgrade which'll take another 8 weeks to complete as I'm waiting for an import.

I'll not be posting this as part of my signature. If anybody is interested in what I'm doing PM me and I'll PM the details.

The DD18 for some reason has far more impact and "slam" in my room but I realise this may not work for everybody.

A "Secret" upgrade!! Whooooooooo ~joke~

The revious was relevant to 2 x DD15's, I understand your current scenario involved 1xDD, and 1x HGS15 so what I posted I guess wasnt a true "apples with apples" comparison..

SOOOOO many factors as well. You just may have 1 only "sweet spot" in your room..

Regardless, I'm sure you are going to have some pretty serious Bass happening.

Congratulations on your upgrade(s).

excellent stuff Darryly great to hear, didnt realise you were a DD owner as well.

interesting what you say re the 18, the hgs is an older tech design so perhaps one factor in there.

the directionality issues that you had with the single HGS15 not a problem with the single DD18 ?

really though one singel DD18 is a much cheaper option than getting 2 DD15s so much easier way out of it I reckon especially if its giving you what you want.

good luck with the upgrades, do post back when all in and settled and let us know what you think.

oh and thanks for posting link to the DD v2.2 software upgrade and support docs ! putting it right in front of me, finally pushed to download. luckily I have a 6 year or so old laptop with a serial port that seems to be coming in handy for this sort of thing, will have to get around to hooking it up to the sub. I like hte sounds of the multiple/separate eq ability for each preset will allow me ot try a few things at a flick of a button or store a few presets depending on source HT or music etc.

ps. by the way guys, did you see the 5 mic kit that comes for DDs now. Allows Eq to be done from multiple points in the room

http://www.velodyne.com/velodyne/products/...17&sid=175p571e

I imagine it would be pricey with a mic costing $100? ea thats upto $500 just for the mics

Thanks alebonau

I've had the DD15 all along and found it great but as you say the HGS compatibilty may have been a factor.

Perhaps the fact that I now have the room treated for sound has helped (only back wall and cathederal ceiling untreated).

stumbled across this via avs,

its the perspex version of the HGS-10 and shows its innards. Saw this at livingstone audio in melb as well - a fully working version and gives some indication of whats inside a velo DD. Keep in mind the one in the photo is the 10" HGS version and apparently the DD is 'beefier' than that again !

check out the motor on that driver

it really is somethign to see in the flesh if get the chance.

Hmmm looks sweet. Wonder if it sounds as good... love the look of the persplex

Holy crapp, gotta new motor guv? That is big in relation to the cone. I would suggest this has a lot of control - even if it loks like only a 10 or 12"??

Hi all as promised a review of the DD-18 part 1. See specs here

Disclosure.

I am not an expert and this review is just my personal opinion. I am upgrading from a SPL1000R to this DD-18 Old & New so it is a huge leap so to speak. The majority of it's service is 75% music and 25% movies. The equipment used can be seen in my sig. I would like to thank all who offered assistance in the setup stage especially macca, al and victor.

In the Box

The sub was extremely well packaged (big thanks to Paul) Box and first impressions were that this was way bigger than I anticipated. In fact when it was delivered I was at work and I received a call from my very upset wife who was complaining about the size and where I could actually put it which sounded extremely painful. It came with all chords etc and this DD Kit and when opened Inside.

Setup

Where it lives now Here It was a simple process to unpack and connect the beast to my 4810 once completed I just turned the volume up on the sub and put "War of the Worlds" blu on to check out the bass...wtf.. there were things vibrating all over the place way too much bass but impressive none the less.

This from stereophile "To calibrate the DD-18, the subwoofer generates tones that is detected by the microphone. The mike "listens" to the sub's output only at the specific frequency of the sweep generator's tone, this allowing it minimize the effects of room modes. The DD-18's software displays the sub's in-room response, from 20 to 200Hz, on a conventional TV set, along with the owner's adjustments to subwoofer equalization, phase, and crossovers in real time."

I never bothered with the software display after the calibration was done I got my spl meter out and adjusted it popped the WOW blu back in for a much better bass experience. Instead of the booming bass emanating from the corner of the room it was now bass that filled the whole room seamlessly, but wait I still need to run audyssey on the denon.

This is where my problems started definitely not the fault of the denon or DD-18 but my lack of understanding of the whole process. The first time I ran it I got weird distance and level settings and it didn't sound good, boomy and dull came to mind. I posted these settings on the forum and the aforementioned members came to my aid with ideas and information that helped me understand why and what was happening.

I then ran audyssey again and with the spl made sure that all levels were within specs, this time it was much closer and finally it was sounding as it should. This was a frustrating process as I knew I was doing something wrong and it was a relief to be able to put some good music on and enjoy the bass which was now very precise and clean. I was watching a blu music concert and was concentrating purely on the bass so I was watching the bass player and everytime his fingers moved I could hear it instantly. So on to the listening tests.

To be continued
