Pros: A very cheap 6.5 inch subwoofer with line, LFE and speaker-level inputs, an easy bass add for a TV, soundbar or small room. It has a 6.5 inch driver and 50W RMS amplifier at a budget $90 price. RCA, LFE, AUX and high-level speaker inputs let it work with a TV, soundbar or speakers. Setup is simple enough for a quick bass upgrade in an apartment or small room.
Cons: Measured output is modest, averaging 105.0dB from 40 to 80Hz and dropping to 94.3dB at 40Hz, so it will not fill a large room or deliver deep movie effects. The ported 6.5 inch design is rated only down to 40Hz. At 17.2 kg it is heavy for its small output, and it is not a fit for a serious home theater.
