#178 Polk Audio Monitor XT12: $319.00 Estimated Amazon eBay
Same family: the Polk Audio XT15 (smaller bookshelf, rated 3.7/5), the Polk Monitor XT20 (larger bookshelf, rated 3.4/5), the Polk Audio XT60 (smaller floorstanding, rated 3.5/5), the Polk Audio XT70 (larger floorstanding, rated 3.6/5), the Polk Audio XT30 (smaller center, rated 3.6/5), the Polk Audio XT35 (larger center, rated 4.1/5) and the Polk Audio Monitor XT10 (smaller subwoofer, estimated 3.1/5).
Pros: The 12” subwoofer of Polk’s Monitor XT range, with a long-throw bi-laminate paper woofer and a 50W (100W peak) Class AB amplifier, rated 24 to 160Hz. It is one of the least expensive 12” subwoofers from a major brand.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from Polk’s measured PSW108 (110.3dB in the 40 to 80Hz CEA-2010 bands). A 50W amplifier is very little for a 12” driver, so output is limited.
