I'm looking at throat wall damping at the moment, how do you guys do it with plastic horns? I've thought of casting poly around it but I'm concerned it will not bond and will separate. Maybe I could just damp with some kind of bituminous putty?

...and on the foam, I have used dacron (with netting to hold it in place) with no negative effects in the end although it takes time to match the stereo pair...just FWIW.

Yes, somewhere in this thread I have posted a conclusion on my dipoles vs. this narrow directivity speaker. I had not changed. If I had to "summarise the summary" it would be like this:

- Econowave/narrow directivity: Better tonality and driver integration, but lacks that last bits of spatial illusion.

- Dipole: Better spatial/auditory scene reproduction, but correct tonality is a real challenge (perhaps too much room influence).

These days what I'm trying to do is to document them. I've started the one for the ewave.

They are 30 ppi "reticulated foam", more popularly known as "mericell" in Australia.

Paul had done a great find:

Ah, very cool. The stuff I use I got cheapie at a fish store, couldn't say porousity with any certainty, but it's very open and very large cells. I found the effect pretty immediate and obvious, and my version had less foam than your, full-up, version. Benefits of noise sensitivity perhaps, I rarely go to anywhere with amplified music.

I can relate to your conclusion, but to my experience auditory scene has allot to do with boxed mid. Using an Open Baffle woofer helps allot. The other aspect is diffuse highs, but you good also argue that a Dipole ads air/room that is not there?

I compaire Econowave with Open Baffle 15" with my other system a 3-way dipole with Seas mid (M15CH002) and BG Neo3W. Both active with MiniDSP.

Hello, My first post here,

I'm looking to build this design of speaker, wondering if there is a regular crossover that can be installed in the speaker rather going with active DSP style, I'm new to the diy world, but since I have one set of klipsch KG 5.5 speakers in my family room, I need another set of speakers to fill the room, and since I have horn tweeters, I thought these would fill in perfectly, any suggestions or help would be greatly appreciated, thanks.

Hi I missed your PM! Sorry.

In any case they are not my design but by late Zilch's. I only did the active/dsp version.

And that would be your loss and your loss only. Tons of info here, parts-express forums and audiokarma.

Gainphile,

I have to apologise for my previous post, as I was under a serious medical issue, my gallbladder ended up getting infected and I was turning yellow, and I needed emergency surgery, I've been on the mend for several weeks, I was really sick, and I was a bit more frustrated than normal.

With so much information that I've read and like over 950 pages from Zilch's thread, I was trying to just get some info from you, or buy some components from you, when you read all the pages that exist, it's so difficult to see what people are using, and if someone like me can't build crossovers, I thought maybe you could sell a set of conventional cross-overs for a price, that's all I was trying to ask or get some helpful info. Thanks!
