Test Bench: The Alpha-5-8 5" Midbass Driver from Eminence

For this test bench article, I characterized the New Eminence Alpha-5-8 5” line array/column array midbass driver. This a new 5” midwoofer from the American Standard Series, a 24-model transducer line of epoxy-acrylic finished stamped frame woofers and midranges. Applications for the Alpha 5-8 include use as a midrange in a multi-way speaker, as multiples in a line array, or as a compact column PA speaker.

It was recognized early on that the speakers benefited from having separate low-frequency and high-frequency drivers, each optimized for its own frequency range. Consequently, names were needed to easily identify the various speakers in a cabinet. This article was originally published in Voice Coil, January 2012.
