#54 Bose 901 Series V: Used availability Discontinued Amazon
Pros: Historically distinctive direct/reflecting architecture uses eight rear-firing and one front-firing full-range drivers to create a very large, room-filling presentation. Erin measured a benign 6.2-ohm minimum impedance, so the raw electrical load is easier than many modern four-ohm speakers. The supplied active equalizer offers user-adjustable tonal balance and is integral to obtaining usable bandwidth.
Cons: Even with the required EQ, Erin measured only about 81dB sensitivity, grossly non-flat response, numerous impedance/resonance irregularities and very high distortion. Output above roughly 90-95dB at his seat became audibly poor; multitone testing reached only about 98dB before the distortion limit. The reflection-dominant radiation prevents precise imaging and makes results strongly room-dependent. It requires the proprietary equalizer and substantial amplifier power despite its benign impedance. Discontinued.
How it compares: Just above it: Triangle Esprit Antal Ez - 9.7Hz higher bass extension (-3dB).
