Fv15HP out of those 2 choices. PB16U will have a decent performance advantage under ~30Hz, but not enough to justify the very large price delta - IMHO

The PB16U is great - but much more expensive than the FV15HP, in fact you should probably be comparing the FV25HP to the PB16 ($$wise) - the FV25 has a tonne more midbass slam over the PB16U and slightly better deep bass performance to boot

Value wise the Rythmik is a better offering imo and stronger below 16hz but the SVS is no slouch.

I would also consider the FV18, JTR Cap 2400, and especially the PSA TV3612 if you are wanting chest slam and strong ULF.

There is a thread where a member compared the PSA TV3612's to the PB16's that you might want to check out. Last page has some YT videos.

I would lean towards the FV15HP, but there are some things I would look into first because it might not be a sub issue.

Have you measured your room response to what it looks like? You could easily have a dip or cancellation in the frequency response killing your midbass around the crossover region. It's pretty common and often the subs get blamed when the problem is a setup and/or placement issue.

The FV15, as the single band PEQ option. I use this setting on my FV18's, for the same reason and work well for me. That said the FV15, is more comparable to the PB4000. And the SVS also have an app, where you should be able to boost those frequencies.

My suggestion, since you are buying from a friend. Is trying both at home in your own environment, to see what sub work better for your need.
While they are bulky and heavy, it might be worth you're time.

Both subs are great, and each have there own advantage. Another option to look at, would be the offering from PSA if you decide to buy new;

They are know to be very strong in the mid frequencies, where the chest slam occur.

+1. If this issue is not ruled out, one can end up chasing one's tail.

another way to measure room is free by using test tones and spl app on phone. play a test tone and plot spl on graph paper from 10-500 or whatever...

They will be close thought I think the Rythmik may dig deeper. A better comparison would be the FV18 and still save you a chunck of cash. Are you limited by space? especially height wise?

Subwoofers: Dual Rythmik FV18s Rev2 with Paper cone, BOSS Platform mini riser, 2 BK LFE

How big is the room ?

Have you tried moving one of the PB2000 directly behind your chair ?

I would go with the 16 ultra. I’ve demoed them side by side and it is was a pretty noticeable difference. The SVS seemed to move a ton of air and has awesome accuracy.

Something to consider, SVS cost $2500 vs Rythmiks $1400, Once you factor the discount for 2 Rythmiks, I think you can get 2 Rythmiks for the price of one SVS

EDIT: I missed the buying used part, if buying used and cost is not an issue, the SVS should have an advantage as it is the bigger subwoofer. Do a demo and buy the one that you like.
