Jay, can you tell us about the SPL/power ratings for the active and passive monitors? I was told at the FAS Forum it's 500W + 150W / 120dB , can you confirm this? Thanks

The sensitivity of the passive speaker is 100 dB/1W/1 meter. It will conservatively take 250 watts continuous long-term power, but its maximum continuous SPL capacity of 120 is even more conservatively based on 100 watts continuous power. An amplifier that is rated at "500 watts" will produce about 100 watts of uncompressed audio without audible clipping. You could use a larger power amp if you want more clean headroom.
The active speaker will produce the same continuous SPL with its built-in power amps, which are rated at "500 watts" for the LF and "125 watts" for the HF. In actual operation, the HF driver will see 10 watts or less at maximum SPL.
