Spatial Audio M4 Triode Master Speakers Overview

The M4 is the entry-level speaker from Spatial. Spatial Audio owner and designer Clayton Shaw wants to enable music fans to experience top-dollar sound without having to pay top-dollar prices, and his line of open-baffle speakers go a very long way toward satisfying that desire.

The M4 Triode Master speakers are upgraded versions of the base-model Hologram M4 and retail for only $2995. They are 93db efficient with a 4-ohm nominal, 3-ohm minimum impedance. And they need as little as 5wpc to get them going. These numbers promise a happy partnership with both low-watt and high-watt amplifiers. But, will they sing or slouch with a four-watt Single-Ended Triode amp? Will they soar or start smoking with a 300-watt Class-D amp? I will listen to them with several amplifiers to find out.
