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.
