Larger models: the REL Acoustics HT/1205 MKII (ranked higher, estimated 3.9/5) and the REL Acoustics HT/1510 Predator II (rated 4.1/5).
Pros: Dedicated home theater design with a front-firing 10-inch CarbonGlas driver and NextGen5 300W Class D amplifier. Delivers energetic, punchy bass response down to 24Hz (-6dB) in a compact, braced sealed cabinet.
Cons: Omits REL traditional high-level speaker wire input, connecting exclusively via line-level RCA/LFE. Sealed 10-inch cabinet runs into compression on sub-25Hz movie bursts compared to 12-inch and 15-inch models.
How it compares: Just above it: PSB Speakers SubSeries 250 - $215 cheaper. Just below it: MartinLogan Dynamo 800X - $101 more.
