4 SEOS-12 Deltalite II 2512 + 3 SEOS-12 JBL 2226H

Hello all. Here is my attempt at building some SEOS speakers. First thanks to all involved with Econowave / Pi / SEOS and DIY audio in general. I've been lurking and wanting some waveguide pro style capable speakers for a while. The Econowave Delites is what I was always eyeing and later JBL systems like Not's and many others.

My 2512 boxes are built but, not done and my 2226H boxes are still various sizes of plywood. Waiting for me to cut out baffles and bracing.

I really can't tell you. I just follow the designers instructions:). Thats a question for the vets.

I wanted the 2226H boxes to be tower speakers because they are going behind a 24" deep screen wall that is padded so it really about 20-21" available. Plus the volume needed can be achieved with the tower height vs using speaker stands. I have all the cut to dimension plywood marked and ready to be cut out.
This is what I planned on doing with the towers.

Does anybody see anything that needs to be changed while I can still cut them differently?

Through reading on the net I've seen conflicting statements on how a speaker should be braced (more vs less) so, I decided to try this. It is only about $50 more in the grand scheme of things so "its in there". They will be heavy and BIG but, they won't be traveling once they are done. The 2512 box is already hefty without the drivers installed so, an enclosure for a 15" speaker in tower form was going to be heavy regardless . Here is another view of the sketch up box.

Thanks Bill. I've read you and others mention about the "+" before. So would this be a better solution than the window considering the interior of the enclosure?

I have been making progress but, I'm not done. The 4 SEOS 2512 boxes are ready to be assembled. The crossovers were completed before the boxes were started.

I lined the boxes with mineral wool and covered that with batting so any loose mineral wool won't go flying out.


I cut the speaker wire to length for the 2512 boxes and weather sealed and duct tapped the waveguides for them.


I just need to mount the cd's to the waveguide then I can assemble the 4 2512 / SEOS speakers.

The 2226H boxes are assembled and rounded over but, not lined with mineral wool and batting yet. I got alot of voids on one of the sheets of Arauco ply. They didn't show until I used the router on the edges.




I wont be putting a finish on them until they all are done. I didn't recess the guide or woofer on any of my boxes because I plan on using this




This is the look I'm going for.


Hopefully I can get them to look as good as the other AVS members subwoofer. Time to go play with mineral wool.

Its alive!!!

They're ALIVE!!! But...no finish on them yet.

I tested all of the speaker components outside of the box before I put them together. Each speaker wire, terminal, CD, woofer and crossover. Then they went in.

I used hot glue to hold the wire in place







That is a 50" plasma in the pic.

LOL. Thanks. Just sitting there temporarily while I tested them after assembly.

I'm going to use the 2226h's with the SEOS-12 and DNA-360s for my LCR. I have completed the 2512 speakers except for the finish. There is no passive crossover out for the 2226H yet so its not complete. I'm going to try an active crossover for the SEOS-12 / 2226H / DNA-360 speakers. I have an Emotiva amp and all the other needed items to measure and do an active XO but, I've never even used REW before. Or measured anything eletronically before. I'm using 8 MFW-15 sealed subs for the low end. I just made 2 F-20 enclosures to try out because I've always wanted to try a horn loaded subwoofer.

The MFW-15's sealed sounds very good and capable. I never see them move much when they are producing their bass notes. I'm using an EP2500 to power the MFW-15s. I have a Crown XLS-402 powering to MJ-18s. Im going to use the Crown to power the F-20s. I'm going to the basement to work on the f-20s now. I need to install speaker terminals, speaker wire, weather stripping, install the 15s in them and screw in the access panels.
