Test Bench: The Wavecor SW275BD01 Home Audio Subwoofer

This month, I characterized the SW275BD01, a 10.75" high-end home audio subwoofer from OEM manufacturer Wavecor. This driver has a well-appointed feature set that includes a proprietary cast eight-spoke (four twin spokes) cast aluminum frame, a very stiff black mica/paper composite cone, further stiffened by a 4" convex black hard paper dust cap. Suspension is provided by a FEA optimized low-loss (high Qm) NBR surround plus dual 6” diameter black flat conex spiders (dampers). This article was originally published in Voice Coil, October 2018.
