Accurate and Musical Sub Recommendation for my 17' W x 30' L x 10' H room - ~$500 budget

Hi guys.

My room layout looks like this:


My speakers are the Selah Audio SA1, stand mount two-way monitors with a Fountek ribbon tweeter and a 7-inch Vifa XT18W09 mid/woofer (rated frequency response of 44Hz-20kHz (+2/-3dB) and' a sensitivity rating of 86dB). The speakers are rear-vented, so they produce amazing bass for their size, but tend to become boomy sometimes. The receiver is Denon AVR-3313CI, so Audyssey EQ room correction will be available.

My room is as shown above (16.5' wide by 30' long and 10' high ceilings), with the main listening area effectively squared off in an almost 17'x17' area by the breakfast bar separating the open kitchen area from the main living area. Typical suburban townhome layout, with carpeted floors

I am looking to add a subwoofer, and my intended usage is 70-80% BD movies / TV, and the rest for music ranging from Bach to Rock to Asian Classical music. I want a fast, musical and accurate sub capable of producing the punch when needed in the BD movies, but yet blend into the music when needed. Output at reference levels is not required, but would like to feel the punch of low bass around ~20-30 Hz. Mid and upper bass response is equally important. Size and placement flexibility is very important due to the peculiar layout of the listening area, so dual subs or even most MEDIUM-to-BIG subs are a no-go in terms of WAF and placement.

Based on a budget of ~$500 preferably, I've been reading great things about SVS, PSA, HSU and Outlaw subs. The new SB-1000 and PB-1000 subs from SVS are particularly appealing, but I am open to suggestions. I've seen Principals from SVS and PSA on this forum, offering advice, and it's greatly appreciated if they could chime in, along with the seasoned bassheads here.

Thanks in advance for entertaining yet another thread seeking recommendations.

P.S. Would it be batchit crazy if I hid the sub in the nook below the mantle? That way it will be away from sight behind the TV and the equipment stand, but enclosed in a 4'x4'x2' nook

Thanks for the replies guys!

I know the room looks gargantuan in the sketch, but I am practically listening to my speakers in the near field. The speakers are just about 10-12ft from the main listening position, and there is almost a half height wall (the breakfast bar) that effectively squares off the listening area to a 17'x17' square. And, I don't ever play at reference, but only at moderate listening levels - between -25 to -15 level on my current Marantz receiver (soon being replaced by Denon AVR-3313CI). So, the prime objectives are accuracy, speed and punch at these volume levels, and also size and placement flexibility.

Yup.. that makes sense. Other than the PB1000 for the output capability, any other recommendations in terms of speed, accuracy and size?

Comparing prices shipped, I am liking what I see with the SVS PB-1000 ($499), SVS SB-1000 ($499), SVS SB12-NSD ($649), Outlaw LFM1-Plus ($620). How do these options compare to each other, and aren't there any other subs that'd fit the bill?? I don't want to go much beyond the $500, if possible, as there are other upgrades to my system contending for $$$. The receiver and potentially the fronts are also on the upgrade list, so $$$ are at a premium.
