Yamaha HS8S: $775 eBay
Pros: Independent CEA-2010 testing records 104.8 dB through 40-80 Hz. The ported, front enclosure with 8” (203mm) driver is intended to add useful bass support without a full-size cabinet.
Cons: Without a published 20 Hz output result, deep-bass capability is less certain than its midbass figure. The 349.2H x 300.0W x 388.9D mm cabinet and 10.2 kg mass still need careful placement and calibration.
