The Two Speakers In Full
Bowers & Wilkins (B&W) PV1D: $1699 Discontinued eBay
Pros: Independent CEA-2010 testing records 85.4 dB at 20 Hz and 108.0 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 2x 8” (203mm) driver delivers substantial upper-bass output for movie effects and music.
Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 342.9H x 269.2W x 358.1D mm cabinet and 18.7 kg mass still require deliberate placement and calibration. Discontinued.

Klipsch HD Theater 600: $399 eBay
Pros: Independent CEA-2010 testing records 108.2 dB (avg of 3/4 bands) through 40-80 Hz. The ported, rear enclosure with 8” (203mm) driver is a compact way to add useful midbass support to a modest system.
Cons: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure. The 353.1H x 317.5W x 317.5D mm cabinet and 7.7 kg mass still need careful placement and calibration.
