#81 NHT SuperZero 2.1: $124.99 per pair Amazon NHT Audio eBay
Pros: A tiny, affordable acoustic-suspension speaker that is easy to place near a wall. ASR measured a 6.34 preference score with a subwoofer, broad horizontal coverage to roughly +/-60 degrees and good 0.111 sound-power smoothness. Measured bass extension of 101.1Hz (-3dB).
Cons: This is intentionally a satellite: estimated in-room extension is only 84Hz and the standalone preference score falls to 3.03. Sensitivity and maximum output are limited, while on-axis smoothness of 0.220 and directivity-index consistency of 3.43 are merely average.
