SVS PB-2000 - Measurements- Testing - Review

SVS PB-2000

There’s plenty of reviews for the SVS PB-2000 but, nevertheless while it was still in my possession I figured I would take some measurements and post them for other readers.

To be honest when I first came into contact with the PB2K we did not get along, at all. Unfortunately to properly get it outputting all she could it took two furniture rearrangements and a week’s worth of time..so I was not a fan of this particular transducer at first but, I have came around after a couple of months of usage to be a big fan of what SVS has accomplished with a single 12” driver.

Speaking of I’m sure most people here know SVS uses a single customer 12” driver by Peerless featuring a cast aluminum basket, dual ferrite magnets, FEA optimized motor, dual shorting rings, extended pole, 2” diameter voice coil, Nomex spider design, tinsel leads, aluminum cone material with a polypropylene dust cap, & rubber long throw surround.

In combination with the customer 12” Peerless driver is a 500Wrms/1.1kWpk STA-500D sledge plate amplifier including on-board proprietary DSP featuring limiter with attack/release function. The plate amplifier also includes a 12v trigger, stereo line level input & outputs with an input impedance of 47 kΩ (unbalanced line level RCA). Continuously variable phase control (0-180), continuously variable (50-160 Hz) 12 dB/octave low pass filter frequency with disable/LFE setting, & fixed 80 Hz 12 dB/octave high pass filter on line level outputs.

The enclosure is a reflex design with an internal volume of 3.84924^3 including a single 4” flared port tuned to 19Hz with an F3 of 17Hz.





Per my subjective opinion just based solely on what my ear is hearing, the SVS PB-2000 has an extremely flat frequency response with more usable bass < 160Hz than is necessarily required in an ID subwoofer. Also for a single 12” reflex design there is sufficient tactile sensations especially if placed in a nearfield location.

This subwoofer in my opinion excels in a home-theater application more so than primarily music as per the sound signature, again; completely subjective and my personal opinion.

Here is the specs for the SVS PB-2000

When you say "customer driver", do you mean that it's an off-the-shelf driver? Or do you mean "custom"? Also, I'd like to point out a small error. You mean >160Hz, not <160Hz

^ It's a custom Peerless XXLS 12" driver, made specifically per SVS requirements. You can't get the exact same model "off the shelf".

Thanks! I’ve grown quite fond of the PB2K. I’d put it right below the Monolith 12” as far as the top tier ID 12’s.
