Test Bench: The SB42FHCL75-6 15” Subwoofer from SB Acoustics

In this edition of Test Bench, we characterize the SB42FHCL75-6, a 15” home audio subwoofer from OEM driver manufacturer SB Acoustics. The SB42FHCL75-6 has an impressive feature set, with a stiff 15” cone, NBR high-excursion surround, and 6.5” diameter flat cloth spider, driven by a 3” four layer voice coil. The motor system utilizes two stacked 20-mm thick ferrite magnets sandwiched between a polished 8-mm thick front plate. This article was originally published in Voice Coil, April 2016.
