Klipsch R-121SW vs SVS PB-1000 PRO

Last updated: September 19, 2026

Short answer: the SVS PB-1000 PRO for better measured output, the Klipsch R-121SW for the lower price. The PB-1000 PRO ranks #37 of 145 medium powered subwoofers, the R-121SW ranks #95, and the PB-1000 PRO costs $600 more.

Klipsch R-121SW vs SVS PB-1000 PRO

The output gap between these two is large and measurable. Audioholics measurements show the PB-1000 PRO outputting 104.2dB at 20Hz against the R-121SW’s 96.0dB, and 110.3dB at 25Hz against 98.4dB, a difference that holds across most of the audible bass range. Its ported front-firing design and 325W RMS amplifier extend frequency response down to 17Hz at -3dB, compared to the R-121SW’s 28Hz low end.

The R-121SW earns its keep on value rather than raw output. Its 12-inch spun-copper driver and 200W RMS deliver what our notes call controlled, musical bass with minimal distortion, and its front-firing design gives more placement flexibility than the PB-1000 PRO’s front-ported cabinet. Our notes call it excellent value with exceptional bang for the money in its price tier.

The PB-1000 PRO adds app control via the SVS app, a feature the R-121SW does not have, along with dual high-grade ferrite magnets and an FEA-optimized motor design.

Weight and size favor the R-121SW slightly: it’s 35.1 lbs against the PB-1000 PRO’s 42.5 lbs, and marginally smaller in every dimension.

Buy the SVS PB-1000 PRO if you want measurably deeper extension and higher output across the bass range and can justify the price difference.

Buy the Klipsch R-121SW if you want controlled, musical bass at a fraction of the cost and don’t need the deepest possible extension.
