Zilch's AK Design Collaborative - Econowave Speaker

[wiredbecker]

Got my ewave's almost done. Boy they sure sound good! Have to put bracing inside. I have the wood latice covers but i might make some with cloth. Not sure yet.

Beautiful work Mike. For grills Zilch ditched the wood lattice which is not acoustically transparent and had his local hardware store build up some custom window screens to fit, epoxied some powerful magnets to the corners of the screen and baffle, then wrapped them in JBL blue grill cloth. Unfortunately that blue grill cloth is tough to find. But your local sewing store should have some suitable fabric that should suffice.

Would JBL HLS820 floor standers make for a good candidate for ewave? They have two 8's and a poor square tweeter horn that blows easy, maybe change to square waveguide? original crossovers cross at 2600, 9.75" width in front.

Hey what's up? I bought window screen kits at Home Depot and they worked fine.

Mike they look great. To add a finishing touch get some black screws for the waveguide.

I don't know anything about that speaker. But somehow that won't stop me from posting.

Check this out, Zilch used the a JBL 8" x 8" waveguide and a Selenium D220Ti driver, the EWave driver. I guarantee you won't blow that. (No guarantees. )
But that is optimized as a system for the AR4x woofer.

Wayne Parham just posted a very succinct, comprehensive set of Notes for the DIYer over at his forum.

He addresses crossovers, box tuning, baffle step, room modes, waveguide size and directivity and provides more in-depth links. Great reading as usual.

Same here. I would assume the bottom half is fine and look at how to upgrade the top half. The JBL 6x6 waveguide is another choice. Zilch mentions JBL used a 2.4 kHz XO in one system that uses it so that might be
something to try if you want to leave the woofer crossover section intact.

Can you dig up a crossover schematic of the original? I would be curious to see if it is a 2.5 way design.

:wave: Hey Duffy! I'll have to try the screen kits on my upcoming Barziwave knockoffs. Home Depot's grow everywhere these days...

Yeah, unfortunately I have a Mac and the software doesn't work for me:sigh:

I was hoping someone had built a box and had port dimension and box size they could recommend.

Here is a handy driver/enclosure calculator, computer independent:

Thanks James, that's really useful for all the mac guys out here. :thmbsp:

Econowave V.1.1 PC Board HookUp Instructions/Large Advent

Finally getting around to these after 2+ years. Zilch had such detailed instructions with these, it would be nice to have a copy. I assybeld one board right away, and looks like I installed all three jumpers J1-J3. Hopefully this is correct.
Not sure about the LP connections.
Anyway if someone has a copy they could they could post or e-mail me, it would be much apprectiated-it would be nice to review the instructions so I can get a feel what was going on.
Thanks

The SD of the Dayton DC300 is 498 cm2. The driver's T/S suggest a closed box but we all know that doesn't work if bass extension is desired. I'll model this up in Unibox for you and see if i can find a nice tradeoff box size between extension and power handling. Something to consider.....this driver's coil inductance (Le) is very high for a woofer, especially one that's being asked to play this high up the FR. It's in box response has an even greater need for BSC than most 12" drivers making this woofer very inefficient given the design. Although it's been used in a lot of Ewave designs, there's MUCH better candidates in the 12" category.

I can scan it and email it to you. PM me your Email address.

almost there from a different view ....

b&c de200 with a 600hz tractrix instead of a waveguide .... and deltalite ii 2510 ..., zilch's xo pcb, and a great help from pcd ...

got to play a little more with drivers geometry - take some measurements and fine tune the values of the various parts of the xo...

sounds great as it is but I think that there is room for improvement .... actually there always is .....


zilch did an awesome project ..... :thmbsp:

EconoWave console in progress...

I think this might be a first for the Ewave scene, an Econowave console!

After much experimentation I have discovered a console really works best in my living room. In the garage/studio I can get a little crazier

This will be the Standard Econowave with 3 Cu ft cabinets. Right now I have the substructure built by joining my two cabinets with 1" angle iron. The console is "largish" at 80" long but only about 13" deep so it hugs the wall a little better than the Motorola console I am currently using. For now (and maybe permanently) the power will be supplied by a Hitachi HA-1100 integrated amplifier.

Next I will be coating the rest of the cabinetry in flat black and installing drivers and crossovers. After that I will begin making panels/grilles that attach magnetically to the steel runners. I think I am also going to make a couple of light bezels with led strip lights that light the face of the components when the doors are opened.

I'll probably start a thread in the DIY section to further document my progress but I thought you guys might get a chuckle out of this.

Vaughn, that's great.
I want one with a bar.

The inset legs are nice.:thmbsp:

Sweet!!!

A 2011 vintage Ewave console!! Zilch would be proud!!

Love the idea. It's really a simple, elegant design solution to the cluttery look of the alternative.
