Zilch's AK Design Collaborative - Econowave Speaker

Hey there Niklas,

Before you go wandering off the beaten track reinventing the wheel, check out all these clear, concise, working Econowave builds that Zilch developed and documented over here on Parts Express:

http://techtalk.parts-express.com/showthread.php?t=215536&page=1

I would suggest building whichever one you can build for the least amount of money--no need to go crazy and build the most expensive one. The Standard Econowave ROCKS.

I'm not really sure where you'll be able to source parts from in Sweden though...

Thanks for the tip. Will read through that and see which one I will build.

Hey there Niklas, it's against forum rules to speak of salable merchandise here in public. Please edit your post to keep the AK dogs at bay. :thmbsp:

I can't help but find that funny. I mean really, a year of intense negotiations? The price isn't even good. I'm thinking the "intense negotiations" involved mostly having emails and phone calls ignored by QSC.

Yeah, when I bought mine they were $12.50 a piece, and they came double boxed for $14 (the boxes were worth more than that!)

Now if I did another project I would think twice before using these, due to the price increase.
 
I love that WG, I think it's worth a lot more than they are selling it for. Yes, I bought mine from QSC direct, for less money. But that was a while ago. If I didn't have them, I would not hesitate to buy at PE's asking price. They are excellent.

I'd like to compare them to the SEOS WGs.
 
I agree with skywave-rider, that is a wonderful waveguide. Even with the lowly Selenium D220ti (bolt-on version!) they can sound "startlingly smooth". My sense is that the SEOS15 is better still, but that may just be bias (the SEOS15 with DE250 is what I'm using now, and I've been involved in its development and testing). SEOS15 isn't quite so tall, which helps with C-C spacing. Either waveguide looks really nice.

I'm pretty sure either sounds significantly better than the screw-on standard Pyle/JBL/Dayton Ewave waveguide, though I;ve never tested them side by side so who knows for sure?

Side by Side here. (6x6, 6x12, 8x8 and QSC)

Well, the standard Ewave waveguide sounds pretty good with the Selinium Neo version, which has a shorter phase plug compared to the D220Ti.(The bolt-on D220Ti has a much shorter path as well.)

Still, the Deluxe sounds better. The only waveguide I like as much as the QSC is the 8x8 (90 deg. by 50 deg.) with the Neo driver on it.

Still have not played with the odd shaped pair of JBL waveguides I bought, P/N 354267-001. They are about 8x7, but tapered on the sides. I have a pair of D220Ti's threaded on them, waiting for time to build a Z-19 HF section to try them with.

You forgot "to me" part :)

I ordered QSC waveguides so i will try them as well (with B&C DE250-8) and compare it to "standard" version.

Woofer question

Hey Guys, anyone tried using a Fane Sovereign 12-300 to match up with the B&C de250? Will this work instead of a Dayton Woofer since I could not find any Dayton dealers in the Philippines. Can you please do the math and tell if it is feasible, they have the specs on the Fane site for this driver but cant interpret very wel ifl it would mate well. Thanks in advance.
 
Response looks nice, extended and smooth on axis. It will be more efficient than the Dayton, but will have less bass. 45-50hz is aobout as good as you'll get. Looks like a solid ewave candidate.

Not likely to ever appear. I wonder if you could get that group from Poland to make a 1.4 or 2" waveguide? Seems there isn't much interest in one.

I don't know... there are promising waveguides (18sound XR1496 says it's constant for 1.2-16 kHz) and plenty of good drivers. It would be really expensive, though.
 
Oops!

Yup, it should say "to me". Once you have a chance to compare though, I think you will agree that it's called "Deluxe" for a reason...:yes:

For music, I've banished all the D220Ti's in favor of the DE250/QSC and the D2500Ti Neo driver. Or my 4430 clone/mod system consisting of 2235H and 4344/2246H in it's original form, but now (reverseably) modified to include a 10" mid and 2405 tweet. Just now putting a power amp on that system after driving it with a little receiver for a year...

The D220Ti's are doing HT, where they don't detract from the picture at all.:D

Thank you, dnewma, I will try to get the pair this weekend. I guess it would be a good match for the de250 in terms of efficiency... but may require a sub? Should i wait for a Dayton instead?
 
Sorry I'm coming in so very late to this party, but I'm looking at putting some LE14As into some C36 Viscount cabinets for eWaves.

I've been looking at a lot of similar builds here and elsewhere, doing a lot of searches, and I think I have the crossover, drivers, legs, bracing, baffles and waveguide issues roughly figured out. The main thing I'm totally clueless about is the port(s), though, and my searches here and elsewhere haven't helped.

What size ports, how long, etc.? I understand tuning for 30Hz is a good idea.

Any help? Thanks!
 
Download one of the free cabinet sizing programs and put in all the T/S parameters for the speaker and this internal dimensions of the cabs and it will tell you the size ports you need.
 
Cool; thanks. I just need to find the T/S parameters for the LE14A, but I suspect they're readily available.

Much appreciated.
