Oh certainly, I'm not looking for anything "mold ready", I'm mostly interested in just the internal profile of the waveguide (since my limited understanding of how they work means I don't really understand how that shape is generated, and why it follows the curves it does). The throat, mounting points, flanges and whatnot I am comfortable generating and fabbing on my own. Even if there aren't 3D files available for the SEOS in particular, does anyone have any others that they know of, or even some resources to read on the math behind the shape itself?

Thanks,
Sam

If you want to keep everything timber matched, go with the 10" Delta Max.

I'm not really sure. I was just saying i would get the boxes or the baffles for what ever people thought was needed.

The BA750 has fantastic build quality, but I'm single, so I figure now is the time for a huge horn system. You're right about the need for a sensitive supertweeter IMO. 24-SEOS takes a 1.4 CD, so that's what I'm looking for.

But seriously, I doubt many 1,4" CDs will do 500hz. Maybe 600 with steep XO. And you will probably have to look in the higher price ranges. JBL 2452H-sl, TAD4003, or maybe the new 18 sound 1.5" exit drivers.
You might even need a supertweeter since the polars will start to beam above 12kHz, instead of 16kHz with a 1".
But if size and funds are not limiting factors I would be doing that as well.
What can you tell me about the BA-750 / Seos 18" combo? Are you not satisfied with the sound or are you just curious about going bigger means even better? Done any measurements?

Hey, shouldn't you have posted a review on the website for that thing? biggrin.gif We need reviews for all this stuff!

If you want huge horns, order the Iwata 300hzs. They are beauties, and I am too single and get away with it. I am still using SEOS for my HT, but the Iwata's are in my stereo audio system.

Very interesting, Josh - is it that you find something about the SEOS superior for high-volume situations, with the Iwata is....?

I have the SEOS 18/TD15M/BA750. Sorry but no review or build thread for awhile. It took almost a year to get all the parts esp. TD15Ms. In the interim I started on a large living room/ kitchen remodel so the speaker project is on the back burner for awhile.frown.gif
Yes, the BA750 looks like it can kick some serious azz and it's got the hindquarters to do it.eek.gif

I'll write a review as soon as I can order and build smile.gif

I am married so my "big" system is banished to the man-cave. It is/will be a work in progress. I opt for the Iwata 600.

BA750 in hand
Iwata 600 pending
AE TD15M per the group buy...rolleyes.gif

Eric,

Would you know of any design in the pipeline that uses a AE TD12H for mid/bass duties?
post #6224 of 9845
I will be doing one VERY shortly with the td12x.

Good to know. Will be on the lookout for your thread, good luck!
post #6226 of 9845
Received all my crossover parts for the Daniels. Erich, if/when you get the baffle done, I'll be ordering 5 more SEOS-12's and 350 compression drivers. biggrin.gif
post #6227 of 9845
I'm getting in a lot of baffles and other things today. I'll get them listed.

The Daniel baffles were made a little large to be on the safe side, and so I can cut them down to the proper size before adding roundovers.

What size would you want those baffles to be?


For the guys using the A&E 12" woofers, will you be leaving the large gasket around the mounting flange or not?

With a slight change to the bracing, the 12" woofers will fit in the smaller 1 cuft enclosure. There's about 2.5" between the pole vent and the back brace on the Definimax. The box is 10.75" deep and has a double thick baffle with one vertical and one horizontal brace.

Make the cutout to include the gasket. At least that way the woofer will fit with and without.

oooooooooof, after much banging around and figuring what I wanna do I think I'm focusing in on the waveguide speakers.... I have a few questions for the masters like Erich and such who have built a lot of these. I was told by ack_bck that the Delta 10 set should pretty handily stomp my Polk Moniter 70's and CS2 center for home theater use. My situation is that the Monitor 70's are just too big for my area (they dip into my projector screen a bit). I have two monster THT's corner loaded that take care of the low end so I crossover at 80 hz on my receiver.

I had Ack_bck mention that I might not seem much difference between the Karma 10's and the Deltalite 12's in my situation because of the 80hz crossover and I won't be using the 12 inch woofers lower frequencies as much. My question to you oh Gods of the waveguids is where is that "sweet spot"??? am I not going to see much difference in upgrading past the karma 10? I mean am I going to see double the improvement in my situation (since it's near double the price between the Karma 10's and the Deltalite 12's)... or maybe go with one of the other "in between" kits? I guess you could say which one is going to be my "best bang for my buck" scenario with the situation I mentioned above.

also since I'm powering them with my Onkyo 605 and not an amp where is the stage where I'd have to use an amp instead of my receiver, I noticed the Deltalite 12 and Karma 12 had a big power increase and DIidn't know if I could fully drive them with my onkyo 605

I hope other experts chime-in on your comparison question. I will be replacing some Klipsch towers (dual 8" mid woofers). replacements will be SEOS12s over the 12". Delta lights. I am hoping to hear more impact in the frequencies just above my 80hz x/o

I don't know what Klipsch towers you have, but I replace the RF3s with the CS1s (which is a similar 2 way designs as the SEOS).

1) Huge imaging
2) Greater dynamics
3) Mid bass kick is awesome
4) That bright harshness is gone

The CS1s also use an Eminence woofer.

I am hoping to build the SEOS soon to replace the CS1s as my fronts. Hopefully I will get to hear the difference soon.

Thanks for that info - very encouraging!
I currently have the RF35s. Based on your input my upgrade result should be very nice!

I'm going to SEOS/TD12M from Klipsch RB-75 system and think it'll be a nice upgrade.

The recess that you routed for me was just large enough for the large rubber gasket that comes with the TD12M.

Yes the SEOS-12/TD12M is a nice upgrade over the RB75's.

I also have M&K S-150 in the special real wood mahogany, but those are still in Cali. I always liked the Klipsch, but never loved them.

Now back to our regularly scheduled programming smile.gif

Here's a teaser shot showing where I am with "Big Mal".
This is with a borrowed waveguide. However; I have some of my very own drivers, waveguides,and L/R delta-light flat-packs on the way, WITH a Big Mal baffle smile.gif
post #6239 of 9845
Erich,

Any change you could tease us with some TD12M baffle eye candy?
post #6240 of 9845
cuzed2,

I don't think that's going to look ugly at all. The dimensions and layout on that baffle area look rather nice to me. Big, though, of course. But that should make for a great center.
