Its past incarnation, the Seas 23F-EW, was a very nice woofer in the very alignment mentioned in the link. Its replacement, while very expensive, looks excellent. I would recommend nothing more than a simple high pass on the tweeter, as this was the suggestion of the technician at Madisound. A Morel MDT-20 was very nice rolled-in at ~2 KHz.

Sure is
I was about to order a pair of cheap but nice looking 12" ACI sub driver
My first subs
But after calculating amps and all I got second thoughts
I would much rather use the money on a fun project with this 10"
In my youth a friend had a 2way with 10" and it was quite impressive
I never could understand how it worked
Today, I think it was a Dynaco kit or clone
I have a small 3way monitor i the works, and have all drivers
If not I would try this 10" instead
Gowa and Tinitus -
As I read this thread, I am becoming tempted to try the Seas again, despite the costs involved.
The Seas 25F-EW is a very smooth driver, and assuming the replacement retains the response characteristics and nice roll-off, you two will be very pleased. A friend of mine who has been designing and building ESL panels for years tried these mated with his own units and a pair of Quads to great effect.
Any recommedations on the tweeter for this go-around? I'm considering another Morel, one of the top-end Scan-Speak Revelator tweeters, or the Vifa ring radiator.

I agree. However, if the resonance frequency is sufficiently low and the crossover point is reasonably high, it shouldn't be an issue. That's why I would shoot for a crossover frequency between 1500 and 2000 Khz. Of course, lower is always better, but then we would need a steeper filter than a first-order high pass. Personally, 1000 to 1200 would be wonderful, but a fourth- order would be necessary with most tweeters I would consider.
Here's another idea: the Hiquophon OWI crossed at 2000 Khz with a fourth-order. The better dispersion of a 3/4" dome matched with a large woofer is tempting.

Good question, that's a never ending job. There are a few options. All of them an application in it's own, with it's own different Xover.
1. SEAS Excel E0006-06 T25CF001
2. SEAS Excel E0038-06 T29CF001
3. SEAS Prestige H1318-06 29TFF/W
(you can start a new thread) The xover is not the same as the phase you mention. It can be a 1order (what sometimes makes things easier) and if not in phase with the woofer, or a 180 (90-90) phase shift can kill it. The phase you mention is in relation to (something) where the phase of the woofer is. No phase (shift between the two in frequency) the better. So if a (for ex.) 3. order and in (they are in) phase (phase coherent between wo and tw on the xover freq. band) the better.
