Zilch's AK Design Collaborative - Econowave Speaker

[donprice]

Just follow the schematic since it is already corrected (reverse polarity) for the LE14. Compare to the schematic in post # 16867 where the woofer has "normal" polarity and is not reversed.

Cheers thanks, I'll open her up and flip the wires (so red to red). This group is great, so much generosity. .

I plan on building a couple Z19 crossovers. I think I will use fiberglass to mount the components to but was wondering what hve people used to secure the components to the board?? Silicon?

 

[turnitdown]

I've seen combinations of that and zip ties, hot glue. Whatever works for you.

Hot glue good idea.....

 

[Katalyst]

Zip ties if you want to change components later on.

I'd like to simulate the Advent Econowave, does anyone have or can point me to .frd and .zma
files for the D220Ti on the PH612?

I seem to recall simulation going on back during the development.

I was looking for these for Altec horns but don't seem to be any out there

Did Altec 'do' constant directivity waveguide horns?

 

[turnitdown]

DANG! I just got a pair of OLAs and have the HF Econowave section to go into them. I don't have the curves, but you have built these, or at least contributed to their development. IF you design a more accurate crossover (not that the first one wasn't) keep us posted. This conversion is one of the best out there because of the deep bass and smooth cross to the horn

Yes. https://greatplainsaudio.com/wp-content/uploads/2017/07/VOTT.1983.pdf

The answer is in this. At least the .zma . http://techtalk.parts-express.com/forum/tech-talk-forum/34467-flex-your-pcd-mettle

Just priced out the parts to build the Z19's... looks like it's going to run around $110 each

Are you going to build the crossovers in a separate box /external ?

 

[roccus]

Yes external... not lucky enough to own 19's lol

 

[Katalyst]

The boxed crossovers can be used for any future projects also.

 

[Pio1980]

I started a pair of e-wave "podules" to contain the upper range driver, horn, and crossover, to have input terminals and bass output terminals, but haven't finished yet.
The crossovers went into a pair of Advent 2 Econowaves.

Longtime lurker. Would love to build a new Econowave and would like to finally get off my butt and do it. What is the recommended woofer for someone that doesn’t have older speakers to repurpose? It doesn’t appear that those bigger QSC waveguides are still available. Recommendations? Thanks for your help.

Build either the Econowave Standard or the Deluxe ( if you source the 152i waveguide or a clone ).

This surplus horn ( click the pic for the link ) is close-enough to the original QSC.



Details are all in the following thread ( click the pic );

I second EarlK on the use of the closeout waves.

Something like this? These were made using the closeout waves.
