This is a Korean cafe music system setup!!! How cool is that..

Jaspert,

Now this is what I call passion. What I way to mix pleasure with business.

Thanks for the link.

This are cafe in Japan, seems like is a trend there too, smaller scale though.

First one is Avantgarde

Second up is GOTO

Very cool! thanks for sharing Jaspert

Okay these horns just look down right scary

Hi Jack,

Finally managed to acquire a full GOTO UNIT 4-way set of drivers. It's the end of the road for me

Congrats Tuyen, its all happening

The holy grail is near your grasp. Bet you are eager to get that lot setup.

Wow, that is awesome!

Can't wait to see them all singing!

Please keep up all posted on the progress.

Woah, will have to make a special trip to Perth to hear them, Tuyen!

Nice. Drool...

What are the cut off frequencies for your 4 ways?

I recommended him to use 200, 1000, 5000, but that won't happen until he got the 150hz horn and GOTO EPH-4001 crossover. His older model of GOTO crossover only allow him to cross at 400hz instead of 200hz.

Hi Jayden

Wouldn't you still need to measure each horn's frequency responce before deciding on what xover point .To take it to the next step measure with the amp being used to power the speakers .

Hi 56oval,

Yes measurement has been done by GOTO during the initial stage, its the crossover point that work best for a full 4 way GOTO setup. That takes the pain from user to measure drivers individually not the mention the chance that one may actually damage the voice coil is not done professionally. We have to remember GOTO driver is extremely sensitive, so one can't really treat them like a cone driver or pro compression drivers that have high power handling.

I understand what you are saying but you also need to take into account the listeners own environment/room amp combination .

What was the xover you were using when I heard your system .

Cheers

The XO that I mention is an active crossover, its made by GOTO. Most of the time active crossover has less dependent to amp compare to a line level passive crossover. Regarding room, that is a tough one, I don't think any crossover especially the generic have taken in to account on what rooms contribute to final sound. For that you can either do a room treatment or if you don't mind, do a room correction.

The crossover when you last listen is a pc based crossover. It's not what I will use ultimately, at least the DAC part. For a pc based crossover to work best, you need a no compromise DAC. There is a DAC that I will use for that purpose on the road map.

So they aren't that delicate if you can can use a PC based xover ,but you will need to be very careful putting figures in and make sure that decimal point is in the correct position .Even in an active system what type of amp used can have some effect especially in the lower freq range's more so for tube amps mainly there OPT's and how early they start to roll off.

It will be great to hear you 4way when its finished .

Cheers

Haha, well its still delicate, but make no mistake PC can be optimize and with a real time linux kernel, It does nothing but xo slope. It's virtually no difference between an off the shelf XO with firmware (except discrete XO) cause it will have operating system in it. A lot of people may have the misconception regarding the stability of a PC, I couldn't agree more, mostly because a generic Windows are prone to that.

And because of that exact reason, GOTO has class A amp design for the active crossover.

Yup 4-way is on the way, this time will be using the Valvet amp to do the job.

What do those German's know ,their using crappy Mundorf,silver wire and ,and current production tubes :party:D.

You need to start a seperate thread ,so we can see your speakers coming together .

I must go ,got some capacitor bank's to make .

Cheers

Mal,

If you were measuring the compression drivers, you might do it with no crossovers in place so they would operate briefly well below their intended bandwidth. I guess that's what Jayden was talking about with driver damage.

that is good news tuyen now i am awaiting for a gtg when you have the project finished

Thanks guys. Will keep you all posted. Martin is currently building me a 160hz l'clech horn for the 505TT mid low. Patiently waiting..

Nice. Drool...

What are the cut off frequencies for your 4 ways?

400hz, 1khz, 6khz all with a first order (6db) slope (according to the numbers written with a permanent marker at the back of the GOTO CF-1 crossover unit! heheh)

I would like to drop the mid-high/high xo point down to 5khz and the low/mid-low point down to ~250-300hz later down the track. Thing is I'm not too fussed with minute changes as when running first order slopes, the differences aren't as noticable as setups that run higher order cutoff slopes.

[ATTACH=CONFIG]28588[/ATTACH]I like Ming Su's set-up...all run off 3-watts 2A3....

Tuyen, you'll have to grab yourself another pair of bass drivers....they're cheap after all....!!

With your new Goto woofers, droping the low/mid low to 200-250Hz should improve the bass some. I had tried, 300Hz, 500Hz and 650Hz with mine and the bass sounds bass with 300Hz. Do keep us updated with your progress.

I'm getting restless and keep having thoughts about 4 ways on the cheap as i have a good 4 way XO, some surplus low power amp and drivers lying around...

Thought I'd share my joy listening to some Hunt Lieberson on with a new driver arrangement and just-installed software, Pure Music with Fabfilter EQ plugin(bye bye Amarra, see you DEQ2496). By my humble standard its sounding pretty scarily good, I dont have a memory of ever hearing anything sound this good. Considering my dogbox electronics (DCX and $500 amps) I'm scratching my head. New amp, dac and passive XO bits in the mail, but I can live happily this is the best I can do.

Nice work b.d. Been keen to drop by your place to have a listen, but unfortunately been flat chat bz

Only JUST managed to replace the altec 416 with me goto woofers. Have them fired up now.. very nice!

(excuse the crazy mess..)
