#127 Monoprice Monolith 10 THX Select: $699 Discontinued eBay
Newer model: the Monoprice Monolith M-10 V2, ranked lower, rated 3.4/5, released Nov 2021. See every Monoprice Monolith generation.
Pros: A THX certified 10 inch ported subwoofer with a sturdy cabinet and balanced inputs, now discontinued. THX-certified 10-inch ported with 500W amp extends down to 20Hz with no internal resonance or port noise. HDF cabinet construction ensures inert enclosure. Variable phase adjustment and robust built-to-last design.
Cons: The 10-inch gives up a lot of output to the 12 and 15-inch Monolith models, and the plain finish has no gloss black option. THX EQ mode is cleaner than the Extended EQ but gives up some of the very deepest extension. Discontinued.
Notes: Product # 24456
