Short answer: the ELAC SUB1010 on measured sound quality, the Monoprice Monolith 8 THX Certified on price. The ELAC SUB1010 ranks #26 of 48 subwoofers at $550. The Monoprice Monolith 8 THX Certified ranks #43 at $350, $200 cheaper.
What the ELAC SUB1010 offers: A compact 10-inch ported subwoofer with useful measured output through the upper-bass range: 102.7dB at 40Hz and 110.8dB at 63Hz. Its small cabinet makes it an approachable option for a modest room or a first 2.1 setup, where careful placement can add satisfying weight without taking much floor space. 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. Ported-room placement can also become boomy; experiment with position and crossover rather than expecting a plug-and-play upgrade.
What the Monoprice Monolith 8 THX Certified offers: A compact 9kg, ported 8-inch subwoofer with THX certification that can suit a small room or satellite-based system without taking much floor space. Measured output is useful through the upper bass: 99.3dB at 50Hz, 100.7dB at 63Hz and 101.6dB at 80Hz. Its selectable THX/EQ modes provide a more controlled option for music than the extended setting. Watch for: Deep-bass output is modest for a home-theater subwoofer, falling to 72.9dB at 20Hz and 86.1dB at 25Hz. It will not deliver the infrasonic impact or room-filling output of a larger model, and the manufacturer lists it as out of stock. Choose it for compactness and moderate listening levels, not for demanding cinema effects.
Buy the ELAC SUB1010 if sound quality is the priority over the price, or the Monoprice Monolith 8 THX Certified if the price is the priority over sound quality.
