Which Type of Enclosure would be recommended for a 14' x 20' living room?

Instead of one sub in the front and one in the back, you can also place on sub on each side of your couch, this is what I run in my HT. It will smooth out bass nodes and their close placement will strain them less.

Agree with everything that's already been mentioned. If you can, go with smaller subs but higher quantity of them (4, 6, etc.). The more the better.

One thing I'd like to mention...you don't like your current sub because it doesn't hit a low enough frequency. Make sure you model whatever you're going to use because many of these subs require a very large enclosure to dig deep. I recall modeling several of the Dayton subs in enclosures that I was comfortable with fitting in my house and couldn't get F3s below low-30s. LFE for movies can hit the teens, so I prefer F3s in low-20s with F10 in teens. Or plan to use something active to boost the low frequencies enough to achieve what you want. None of my subs use any boost (except the one in my car), but that's because I'm poor (and cheap...a nice combo). If you plan to EQ in the low end extension, then you can make a couple of nice compact ones that will dig low. But that costs mula.

Thanks once again for the influx of information.

Hm after careful reconsideration, I think I will go with two separate sealed enclosures built to ~3.1cu ft each, each box with a single 15" Ultimax subwoofer.

I did a little research on the crown amp, however, I am really liking this amp, what do you guys think?

Stereo output, set to low LF crossover.

It also seems that it will be more budget friendly in that I dont have to buy 2 of the Dayton-1000w amps ~$660 compared with ~$300

The EP4K is a great sub amp, it's actually used by a large percentage of DIYers. Google the fan mod for it (or search around AVS Forum), it is loud with the stock fan. It has been measured to put out about 650 watts per channel at 4 ohms down to 20hz. You will not need a high pass filter with the UM15 in a sealed box with that amp.

I recall reading somewhere on the IB boards about this amp and the fan mod as well. The IB guys love it, but yes, the fan does run loudly and it does run often as opposed to the crown amps where most of the time the fans don't even switch on IIRC.

Anyway, I think you're in for one hell of a setup with dual 15" Ultimax sealed subs. Jealousy is setting in quick.....MUST. LEAVE. NOW.

If 3 cu ft is a hard limit, consider using the Umax 12. In 3 cu ft., Unibox says it digs deeper (F10 is 18.7Hz vs. 20.5Hz for Umax 15 in 3 cu ft.) at a slight SPLmax penalty (-1.3dB at 20Hz). If you can go 4 cu ft, F10 for Umax 15 drops to 18.4Hz - same LF extension - and the SPLmax penalty grows to 3dB, as one would expect from the spec sheet.

To be fair, however, these are minor differences, likely not audible in your application.

The EP-series are good value amps, but with the same shortfalls as Crown in a SW application. Behringer's iNUKE series amps have none of the drawbacks...

Where do you see the Umax 15 needing a high pass filter at all in a sealed box? This is 400W, 4 cu ft sealed, as above.

Still seems to me that you're saying he EP4K rolls off at 20Hz, negating the need for an infrasonic HP filter. Just pointed out the system is excursion safe inherently, regardless the amp LF characteristics.

Have fun,

I've only seen measured max output at 20hz, not below.
