ELAC SUB1010 vs Monoprice Monolith 8 THX Certified

Last updated: October 21, 2026

Short answer: the ELAC SUB1010. It ranks #36 of 73 subwoofers by sound quality (rated 3.3/5) at $550 and is still sold new; the Monoprice Monolith 8 THX Certified ranks #66 (rated 2.7/5) and is discontinued, so it is only an option used.

ELAC SUB1010 vs Monoprice Monolith 8 THX Certified

The ELAC SUB1010 is the better-sounding choice. An affordable compact 10 inch ported subwoofer that adds bass weight to a modest room or a first 2.1 setup. Watch for: Deep-bass output is limited compared with larger subwoofers, with 96.5dB measured at 31.5Hz, so it is not the right choice for demanding home-theater effects or a large room.

Why pick the Monoprice Monolith 8 THX Certified: A compact THX certified 8 inch subwoofer with selectable modes, sized for a small room or satellite system. The catch: Deep-bass output is modest for a home-theater subwoofer, falling to 72.9dB at 20Hz and 86.1dB at 25Hz.

Buy the ELAC SUB1010. It is rated higher for sound quality and still sold new, while the Monoprice Monolith 8 THX Certified is discontinued.
