My SEOS 15's from awhile ago have been aching for a new speaker to go into.

In honest opinions, would I be better keeping my TD12X custom towers, or would the new Fusion 15 provide better performance? I don't need full range, as I have two 18" subs. I could also use a little less height right now than the 40" of the towers, as I just installed a projector and the tower speaker height is keeping me from reaching "optimal" screen size.

You can also build the cinema 88 with two 8" side by side below the SEOS-15 if you want to redcue the height.

I think you would - assuming you've gotten the crossover really, really well dialed in. If you're using a half-assed crossover then you're not squeezing the full potential out of your systme.

That would be Bill Waslo's crossover IIRC, so I would assume that part is covered. Although I have heard it said that Bill's methodology is to concentrate on the technical aspects of flat FR, directivity matching and good solid phase behavior while leaving it for the end user to "voice" with EQ if desired, in contrast to some designers who build and tweak for a specific sound. So depending on your definition of "dialed in" I suppose there might be some room for adjustment and personal preference.

bhazard, my take on it is that going to the 15 would gain you controlled directivity down a bit lower (measured, not necessarily audible) with the tradeoff being you lose the AE drivers' world-class distortion numbers (again measured, not necessarily audible, especially at sane volumes). I say you keep the towers and build the 15s and host a listening party.

I find it near impossible to voice a clean lifelike voice with eq. To me that's one of the main things that I want the xo to accomplish . I find it easier to eq the lows and highs then midrange .

nice work matt. I'm a little surprised that you didn't put more 'down angle' in the response. any comment on that?


the off axis performance of that woofer is quite interesting too. strange off-axis performance makes it look like a horn loaded system down to around 500hz!


the crossover matching is REALLY good--about as good as i have ever seen. i couldn't tell you where the crossover is just looking at the off axis response. it could just as easily be 700hz as 1400hz. very smooth transition.


most of the chop in the upper end could be eq'd out. have you guys thought about an upgrade crossover that includes 2 or 3 minor eq adjustments?


the response buildup around 100-150hz suggest a cab that might be a little small. did you guys take a look at 3 c.f. sealed? winisd has that driver at -3db, q=0.7, 80hz which would be ideal for thx mains, at least in some sense.


sounds like this one is a real winner.

Listen. It's All Good.
