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.

In this Test Bench, Voice Coil characterizes two high-end compression drivers and horns from Eminence, the N314T-8 with the H14EA horn, and the N320T-8 with the H2EA horn.

The main difference is the N314T-8 is configured for a 1.4” throat, and the N320T-8 is configured for a 2” diameter throat. This article was originally published in audioXpress, March 2016.
