A Hybrid Valve MOSFET SE Amp - Complete Project

Published in two separate parts in audioXpress October and November 2007, this hybrid amp design is a detailed and interesting project, frequently referenced by other DIY audio enthusiasts. We thought it was time to make it available online in its entirety, in the best possible quality. The article discusses the unity-gain, single-ended MOSFET output stage, the valve voltage amplification stage and wraps up with the power supplies, printed circuit boards, and construction.

Test Bench: Dayton Audio LW150-4 6” Ultra-Low-Profile Midwoofer

This edition of Test Bench characterizes Dayton Audio’s new 6” diameter ultra-low-profile midwoofer, the LW150-4. This is a new ultrathin profile cone 6” diameter midbass driver featuring a six-spoke cast-aluminum frame with a 1.5” total depth. The depth reduction is significant as the motor assembly is housed inside the frame and uses a neodymium slug and a 1.5” diameter return cup that incorporates a T-pole.

VC Spotlight: CLIO Pocket User Report

In this article, Vance Dickason explores Audiomatica's CLIO Pocket analyzer. Rather than go into detail regarding all the measurement routines available in CLIO Pocket - audioXpress already published a thorough review in the October 2015 issue - Dickason gives practical examples using measurements for a couple of drivers in the same way he does for his monthly column, Test Bench. This article was originally published in Voice Coil, March 2016.

Update a Pair of MTX 5i 5.25” Bookshelf Loudspeakers

Update a Pair of MTX 5i 5.25” Bookshelf Loudspeakers

I recently purchased a pair of MTX Audio Monitor 5i 5.25″ bookshelf speakers because I needed small monitors for a new computer. I do some audio restoration, so I wanted good sound quality when I wasn’t using headphones. My tests determined that the reviewers were right about the MTX 5i’s weakness in the midrange frequencies. I measured the response and it was not especially flat. This convinced me to update the drivers. This article was originally published in audioXpress, June 2013.

Test Bench: Dayton Audio PM220-8 Wideband Neodymium 8” Woofer

May 18, 2016 by Vance Dickason

Test Bench: Dayton Audio PM220-8 Wideband Neodymium 8” Woofer

The transducer submitted to this Test Bench came from Dayton Audio and is the PM220-8, which is a wideband (full-range) neodymium 8” woofer. This driver is similar to the PS220 full-range 8” featured in Voice Coil October 2011. However, unlike the PS220 which is intended for use in a single-driver speaker, the PM220-8 is a wide bandwidth version intended for use as a midbass or midrange driver in a multi-way speaker system. This article was originally published in Voice Coil, September 2013.
