#186 Polk Audio Signature Elite ES8 Subwoofer: $359.00 Estimated Amazon eBay
Same family: the Polk Signature Elite ES10 (smallest bookshelf, estimated 3.1/5), the Polk Signature Elite ES15 (bookshelf, rated 3.5/5), the Polk Signature Elite ES20 (largest bookshelf, rated 3.7/5), the Polk Signature Elite ES50 (smallest floorstanding, estimated 3.8/5), the Polk Signature Elite ES55 (floorstanding, estimated 4/5), the Polk Signature Elite ES60 (largest floorstanding, rated 3.4/5), the Polk Audio Signature Elite ES30 (smaller center, estimated 3.5/5), the Polk Audio Signature Elite ES35 (larger center, estimated 3.4/5), the Polk Audio Signature Elite ES10 Subwoofer (larger subwoofer, ranked higher, estimated 3.7/5) and the Polk Audio Signature Elite ES12 Subwoofer (larger subwoofer, ranked higher, estimated 3.8/5).
Pros: The smallest subwoofer in Polk’s Signature Elite range, matching the ES speakers in style. An 8” mineral-filled polypropylene woofer and twin Power Ports are driven by a 100W amplifier with DSP and Polk’s Time-Smart phase control, rated to 32Hz.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from Polk’s measured HTS 10, the 10” sub this range replaces (114.8dB in the 40 to 80Hz CEA-2010 bands). With a smaller woofer and a third of the newer models’ power, it is suited to small rooms.
