Have I gone overboard? Am I asking the right crowd?
SVS persuaded me that the PB-1000 Pro would not pressurize the 3,000 ft3 basement. Do you agree? So I bought a PB2k (great sale!) to go with the KEF Q150 LCR. Yikes, that sub dominates the visuals, like maybe I should downsize to the PB1k. But wow, did I feel the opening sequence to Blade Runner 2049!! Even with the sub at -10dB and Audyssey calibrating at -12dB I felt I had to tamp it down. Maybe it was my imagination, but all the audio seemed louder; I was watching at -20-25dB on the AVR whereas I was watching Jason Bourne at up to -15dB.

SVS should know their Subs capability better than I, and they'd never try to upsell a Customer => would they?
Lots of members here are of the opinion that you can't have too much Sub, but the only opinion that really counts is yours.
Moving forward from your old Energy Take Classic Sub is quite a leap, and as the PB-2000 is retired, I'm assuming you've got the PB-2000 Pro which is rated 19-240 Hz ±3 dB utilizing a 550 watts RMS (1500+ watts peak) amplifier. The Energy Take Classic Sub was rated 33- 150 Hz (±3dB) with a 50-watt RMS amplifier, and I'd be quite surprised if it could really dig down to 33 Hz, and with only 50 Watts at it's disposal, it's output would be meager. Hence the dramatic change you are experiencing. You are hearing bottom end that you've never experienced before.
You may want to experiment with moving (UGH!) the PB-2000 Pro out of the corner and to under the left Speaker to reduce corner loading; as it may make it sound less "boomy" to you.
I've assumed you've checked out

All in all I hope you are enjoying your new system, and find it worth the effort, and expense.
