Test Bench: Scan-Speak 32W/4878T00 Subwoofer

This Test bench examines the 32W/4878T00 12” subwoofer from high-end driver manufacturer Scan-Speak. Over the years, Scan-Speak has become known for its midwoofers and tweeters, which is to say that its products can be found in a large percentage of the high-end loudspeakers on the market in the last 40 years. Having used Scan-Speak’s drivers in designs for some of my consulting business customers, I found it also makes some excellent subwoofers.

This month’s Test Bench is dedicated to a new woofer from Motus, a fairly new company in the esoteric end of the home audio business. The transducer under test is the Motus UH205PW1, an 8” mid-bass driver with a really nicely configured six-spoke cast-aluminum frame, FEA optimized motor design and a nice overall physical appearance.
