I made a simulation of what 1,600w would do to the excursion in your enclosure. You could easily power TWO Titanic Mk3's with a single ep4000.
Someone calls me a 'Quick Draw'? Really? I thought I was called 'Sub-bass simulation McGuillicutty'. *laughs* jk

I have a room ca little over half that size and have 4 x 21's and 6 x 18's in it lol.
As far as amps go, don't read to much into "rated output" It generally doesn't mean much. the ep4000 is an amazing amp for the money but running your subs bridged, your just asking for a VC meltdown I'm afraid.

I used to have a 35x45x15ft living room and I used to play badminton in it (I'm not joking). Your 25x45x15 room is getting close to the size of a real IMAX, Barn or Prince of Brunei dude.
I'm currently running 14 channels of bass amplification with a bass generating woofer on each one (that is 35,400 peak-watts total), in a room that is just under 1/2
the cubic volume of your room!!!
Too much power!!! No wait, not enough power!...lol
I tell you what aard, if you are looking to spend more money these guys are very very convincing... Spend too much time around here and they will convert you to the basshead you never knew that you were...
Here is my suggestion to you. While the content that you play (jazz) may have some very bass competent tracks, the genre itself isn't well known for giving subs a great workout.
Maybe take the time to download some sinewaves from Realm of Excursion. Play them through your system just to get a good gauge on your sub/amp behavior at a particular consistent fq. As Scotts modeling shows, you should have MORE than enough amp to push your subs given your current box size. Of course you need to heed the dip switch recommendations and take a look at your AVR, as tgse3 suggested, to see if you have a crossover set as well.
You mentioned you initally had filters set for the sub to output 50-120Hz, correct? Man, in my opinion that sounds like the job of a woofer not a "sub" woofer. There are a lot of people set their crossover at 50Hz for all content below
that to be played through their subs.
Of course, I don't think I will ever not recommend more bass, so if you are down for building 8 more cabinets with 18's then I'll follow your build thread with a smile!
You should probably go for the FTW-21 in such a large space! 4, 8 or 16 of those sound like some real fun!
