Test Bench: Five Mid-Price Subwoofers
(continued)
Velodyne DLS-5000R
This subwoofer's operation was pretty straightforward. It can deliver 110 dB SPL or better from 32 Hz up, but its response appears to be cut off sharply, by design, below 25 Hz. Control function is reasonable, and the remote control is fun.
