The PB17-Ultra R|Evolution takes a different approach with its ported design, offering even more output capability and deeper bass extension down to 12Hz. With three tunable ports and a larger cabinet, it delivers thunderous home theater performance that can pressurize rooms over 2,000 cubic feet with ease. While sharing the same advanced driver technology and amplification as its sealed sibling, the ported design provides about 3-4dB more output in the mid-bass region and allows for different tuning configurations to match your room and preferences.
At $500 more than the SB17-Ultra, the PB17-Ultra R|Evolution represents a compelling value for those with the space to accommodate its larger footprint (25.0"H x 21.7"W x 29.3"D) and the desire for maximum output capability. While it gives up a small amount of transient speed and control compared to the sealed design, it rewards users with visceral impact for movie effects and the ability to reproduce the lowest organ notes in concert hall recordings. The choice between the two often comes down to room size, space constraints, and whether your priority is absolute output capability versus precision and compactness.

The Klipsch Reference R-121SW ($599) takes a more conventional approach to subwoofer design, offering solid performance for its price point with a 12-inch spun-copper driver and 200W RMS amplifier. While it can't match the SVS's extreme capabilities, it delivers impressive bass extension down to 28Hz and provides enough output for small to medium-sized rooms. The Klipsch's rear-ported design helps improve efficiency, and its straightforward controls make setup simple for most users.

When considering value, the Klipsch presents an attractive option for those who want quality bass without breaking the bank. While it lacks advanced features like app control and room correction, the R-121SW handles both movies and music capably at moderate volumes. Its limitations become apparent only in larger rooms or at reference listening levels where the SVS clearly demonstrates its superiority. For typical living room setups and casual listening, however, the Klipsch delivers satisfying performance that belies its modest price point, making it a sensible choice for budget-conscious buyers who don't need the absolute ultimate in subwoofer performance.
