Test Bench: Volt RV3143 Studio Monitor Woofer

The driver for this month’s Test Bench explication comes from the UK. Volt sent the 12” RV3143 Studio Monitor woofer, which is probably the most uniquely designed woofer to come across my desk in a while — there is no frame on the back side of the driver! The Volt Radial Technology consists of a front-mounted eight-spoke proprietary cast aluminum frame that is mechanically coupled to both the back plate and to the top of the pole structure/phase plug, in contrast to a normal rear frame that is only coupled to the motor front plate.

Voice Coil magazine welcomed Volt Loudspeakers UK to Test Bench in this edition! The driver tested this month was the hot-off-the-production-line new 2” midrange dome, the VM527. The VM527’s features include a coated single piece fabric dome/surround, FEA-designed ferrite motor structure, a 52 mm diameter voice coil, short flare horn built into the rear mounted faceplate, a 91 dB sensitivity, and 75 W (AES) rated power handling.
