used DRA Labs’ MLSSA system, a calibrated DPA 4006 microphone, and an Earthworks microphone preamplifier to measure the quasi-anechoic frequency- and time-domain behavior of one of the McIntosh ML1 Mk IIs—serial number BBB1256—in the farfield. The manual doesn’t mention the preferred listening axis. However, although the tweeter is a low 31.75" from the floor with the loudspeaker sitting on its stand, the stand’s slight tiltback will aim the tweeter at the ears of a typical seated listener. I therefore performed the farfield measurements on the tweeter axis. I used an Earthworks QTC-40 microphone, which has a ¼” capsule, for the nearfield responses, examined the loudspeaker’s impedance with Dayton Audio’s DATS V2 system, and investigated the enclosure’s resonant
