A801/810

Frequency response = 850 – 21,000 Hz
Power handling = 25 Watt
Impedance = 8 or 16 Ohm
Sensitivity = 104 dB @ 1W/1m
Diaphragm = all-metal aluminum dome driven by a 45 mm diameter voice coil
Flux density = up to 17,000 Gauss
Net weight = 6.2 kG
Diameter = 136 mm
Horn throat diameter = 1 inch (801) = 1.4 inch (810)
Mounting hole diameter = 101.6 mm (4), 82.5 mm (4), 76.2 mm (2), 57.2 mm (3)


Frequency response measured with Lansing 1 inch 1217-1290 reference horn / acoustical lens (which is responsible for smooth roll off above 15 kHz) under normal living room / listening conditions show extraordinary linearity of only ± 1.5 dB within the range of 800 - 15,000 Hz. Sound is hard to describe but one word does match it very good: life like.
