Now that preliminary specs for Alexia v2 are posted, I see this differences:
Alexia - specifications
Sensitivity: 90 dB @ 1W @ 1m @ 1k
Nominal Impedance: 4 ohms / minimum 2 ohms @ 80 Hz
Frequency Response: 20 Hz – 32 kHz +/- 3 dB
Approx. System Weight Per Channel: 256 lbs (116.12 kg)
Alexia v2 - prelimimary specifications[
Sensitivity: 89 dB @ 1 Watt @ 1 meter @ 1kHz
Nominal Impedance: 4 ohms / minimum 2.54 ohms @ 85 Hz
Frequency Response: 19 Hz – 32 kHz +/- 3 dB Room Average Response [RAR]
System Weight Per Channel: 260 lbs (117.93 kg)
The sizes quoted for the drivers are the same for the original and the v2 Alexia. The WAMM tweeter is the same 1-inch size as the Alexia tweeter and Wilson materials seem to suggest Alexia v2 will have the WAMM tweeter.
