Test Bench: Volt Loudspeakers VM527 Midrange

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.

Test Bench: SEAS E0060-08/06 6.5” King Coax

Test Bench: SEAS E0060-08/06 6.5” King Coax

The driver featured in this Test Bench is the new E0060-08/06 6.5 “King Coax” from SEAS. Recognized for several years for its high-performance coaxial midrange/tweeter drivers, SEAS developed this new driver at the request of a studio monitor customer who wanted a compact three-way monitor and asked SEAS to develop a midrange + tweeter coax. The King Coax received its name from the copper ring under the tweeter, which resembled the look of a crown. This article was originally published in Voice Coil, June 2017.

SB Acoustics Satori MR13P-4. A New Home Audio 5.25” Midrange Driver

SB Acoustics Satori MR13P-4. A New Home Audio 5.25” Midrange Driver

The subject of this month’s explication is the SB Acoustics 5.25” MR13P-4 Satori midrange. As with the MR16P-4, the MR13P-4 is nominally a midrange version of the SB Acoustics MW13P-4 5.25” woofer, but with higher sensitivity and shorter Xmax. The MR13P-4 is built on a cosmetically attractive six-spoke frame that has a minimal reflective footprint behind the cone to reduce reflections and a completely open area beneath the spider mounting shelf for enhanced cooling— both highly desirable attributes.

The MR16P-4 6.5” Satori Midrange from SB Acoustics

The MR16P-4 6.5” Satori Midrange from SB Acoustics

The subject of this Test Bench is the recent SB Acoustics 6.5” MR16P-4 Satori midrange, which is nominally a midrange version of the SB Acoustics MW16R-4 (first reviewed in the November 2011 issue of Voice Coil) with higher sensitivity and shorter Xmax. The original Satori MW16R, while looking cosmetically similar to the Scan-Speak Illuminator 18WU series, was a well-designed driver that has established itself as a true high-end home audio competitor.

Test Bench: B&C Speakers 8NSM64 Closed-Back Midrange

May 17, 2017 by Vance Dickason

Test Bench: B&C Speakers 8NSM64 Closed-Back Midrange

The 8” 8NSM64 is a rather unique new pro sound midrange driver from B&C Speakers. It’s a closed-back midrange! Closed-back midranges are often associated with cheap speakers because by using a frame with no relief holes in the back, you don’t have to build a midrange chamber. In this case, the 8NSM64 is a very high-power handling (500 W continuous) 8” midrange for professional PA applications, with a reasonable volume that can be damped with absorption material.

Test Bench: Scan-Speak 18M-4631T00 Revelator 6.5” Midrange Driver

April 13, 2017 by Vance Dickason

Test Bench: Scan-Speak 18M-4631T00 Revelator 6.5” Midrange Driver

This Test Bench characterizes the Scan-Speak 6.5” 18M/4631T00 Revelator midrange driver, nominally a midrange version of the Scan-Speak 18W/8531G00 with higher sensitivity and shorter XMAX. The original Scan-Speak 18W/8531G00 was a true high-end audio classic and probably one of the most visible high-end drivers ever used in high-end loudspeakers. This article was originally published in Voice Coil, June 2016.

Eminence sent a 6.5″ driver from their lightweight Professional Neodymium Series, the Alphalite 6A, which, along with the Kappalite and Deltalite series, makes up the neo woofer/midrange offering from Eminence. The Alphalite 6A is described as a lightweight pro audio mid/bass driver, designed for sealed, vented, or infinite baffle applications.

Test Bench: Celestion CF0617M Prosound Midrange Driver

The transducer I received for this month’s Test Bench is the CF0617M, a new high power handling 6.5” midrange, from Celestion. The CF0617M is one of my favorite formats in a pro sound mid. Features include a four-spoke cast aluminum frame, a light-weight curved profile uncoated Kevlar loaded paper cone, a 1.75” diameter voice coil and a 120 mm × 15 mm ferrite magnet. This article was originally published in Voice Coil, December 2015.
