The SEOS project has a great lineup of waveguides with different capabilities (the largest is a 24" that is said to hold pattern down to 500 Hz),
im not sure there is a "best" most of the designs out there now are around the 12" horn, and chop has his 24" horn mega mains
there are 15" and a18" horns coming as well as smaller ones.
I think that molding CD horns is a great idea and should have been done years ago. Building them out of wood is a PITA for sure...
Hi Bob. Well, Bill Waslo's Acoustic Elegance TD12M design of course!
I assume that AE's TD12M is the same speaker (12" version) as my Lambda TD15M, right? It is really a great midbass driver and has served me well over the years.
Hey Bob, my comment comparing the SEOS speakers was comparing to the golden ear speakers. Not your unity horns. Your unitys could easily be better. Just to clarify.
Gotcha. Without even hearing them, I now have a distinct feeling that I would be disappointed by the SVS and GoldenEar speakers once I got them home. That's why I wanted to talk with you guys.
Since I have been in a building mood lately, as evidenced by the new sub I am building despite the fact that I really don't need one
, I think that perhaps I will see if I can find a high quality SEOS MTM design to try out as a center speaker, just for kicks. The prices I have been seeing over at DIY Sound Group are unbelievably low, so it would not be that big of an investment, and I would get a feel for how well SEOS compares to the Unities, and whether or not I can still hear the horn honkiness.
A note on the horn honkiness: I am being very very picky here. I don't want people to start thinking that the honkiness I am talking about is a big deal. Most people who have listened to my speakers think I am crazy, as they cannot hear what I *think* I hear.
But I think it would be a fun project to build a new SEOS center speaker, though the only one I found so far utilizes 8" drivers. I would like something with at least 12" drivers, and 15" (in order to match my current configuration) would be even better. Anyone know of such a project?
@Mfusick - If these SEOS designs are even half as good as my Unities, then the value represented will be outstanding and very hard to beat. The pluses of these types of designs are:
1. High sensitivity - My Unities are rated at ~101db
2. High power handling - even though they require very little power, they can also handle great amounts of power and still remain VERY clean. I am powering mine with 250 wpc RMS and can crank them without a hint of distortion. Depending on the midbass driver you choose for your SEOS design, I assume that the same could be done with them.
3. Virtually no compression with very high dynamic range. Some of the movie tracks I have listened to have scared me to the point that I could not believe that the speakers could survive the transitions (like in Super 8
) from quiet to loud passages, with virtually no compression, but they did...
4. CR horns (or waveguides as they are now called) have a much bigger sweet spot. They sound the same just about anywhere in the room except the extreme corners.
5. Oh, and let's not forget how cheap and easy they are to build!
Of course I am just speculating that SEOS is that good, but based on the design concept, it should be. I will be glad to report back once I build a SEOS speaker myself and have the opportunity to evaluate it properly.
