which of these 2 subs?


Factoring in bang for the buck, sound, reviews, and cost I have narrowed down my choice of 2 Model subs... Problem is not sure which is best for me. May I list my current audio set up below and get some feedback on which subwoofer of the 2 or perhaps an alternate option at same cost that would be better?

(I must mention that although I have 5 active speakers, that I have zero interest in Movie or surround sound.) I have 5 active speakers in Stereo mode only because "just IMO" For strictly SACD, CD, and my Pandora I like the sound of multiple speakers. (Most music Audiophiles would call that foolish.)

SETUP: 2 Kliptch RF-7 Reference Floor speakers.
2 Definitive Technology Studio Monitor 65 Speakers.
1 Definitive Technology Pro Center 2000 Speaker.
1 Emotiva XPA-5 Integrated Amp.
1 Oppo BDP-103 Universal Player.
1 Emotiva UMC-200 7.1 channel Pre-amp.

(Yes, I know my system sucks from an Audiophile standpoint.)
I keep all this forward facing to reduce any surround effect.

I'm absent a badly needed subwoofer. Seriously ready to pull the trigger on one of these 2 Subs, but not 100% positive: POWER SOUND AUDIO-XS15se or the XV15se.

My goal: stiff, tight bass that delivers a hard punch you can feel in your chest. My living room is only moderate in size. I already have plenty of high tone, great Mid-Range, but a bit lacking in that hard rock bass punch.

Are the above Subs a good choice? If so which one for the fast hard punch I want? Another sub idea? I'm all ears.
problem is I'm not among the wealthy so must be below $800 on Subwoofer.

Sorry all the info, but if I fail to provide it then you guys can not give accurate advice.

Thanks.

You may also want to peak at the subwoofer test results at HTshack.com

They measure for bass extension, clean output capability, and "tightness" (group delay). It's interesting and educational. SVS, Rythmik, and HSU all test very well, particularly for the price. Many better known brands fare much less impressively. In some cases, newer models may render some of the results less useful, so I'd look for models that either current or substantially similar to current models.

These test results may not be a perfect predictor of subwoofer performance in your system in your room, but in my (necessarily limited) experience, it's pretty reliable.
I second the Rythmik recommendation. I prefer the sound of sealed subs over ported designs. I have two 15" Rythmik subs in my HT set-up. They're fast articulate and when set-up in combination will move the entire house. Great for music and movies.
And I will second Martykl's suggestion to look at measurements at HTShack forum. This guy Ikka (if I recall his ID) measured many many subs with an open mind, in a repeatable way, and found interesting results.
