Exactly my concern too! My ceiling is 8 ft. high, my ear level is about 50 inches from the speaker, so when angled 30 degrees and placed just above my L/C/R that makes the 8320a about 8.5 ft away (2.6m). For me to get 86dB at my listening position and peaks above 90dB, I would have to increase the SPL at 1 meter to at least 96 dB and now that we get these measurements from Amir:

I have grave doubts that these speakers can handle it. On Genelec's website, the specs show that the peaks are capable of 107 dB at 1m; knowing that I would cut them off below 120Hz, I originally figured it was OK because I should easily get 86dB based on those peaks right? But of course I wanted verification of capability up to 96 dB so I sent
@amirm both the 8320 and 8330.
Sadly, what I'm seeing here is that tweeter compression hits hard above 10kHz while distortion shoots through the roof below 1kHz. In real world terms, I'm possibly losing ambient cues relating to the "air" and "hiss" from flying jet fighters or screaming dragons overhead ("
The brilliance range is composed entirely of harmonics and is responsible for sparkle and air of a sound. Boost around 12 kHz makes a recording sound more Hi-Fi"). I'm not as bothered by the distortion above 120Hz although not happy about it. I've asked Trinnov if the Alt16 provides frequency bandwidth information per channel channel so I can see if I'm losing audible information but they said No (not yet? I'm going to try to lobby for this if it's not already in development).
It is these measuremenst that makes ASR so valuable for speaker selection - I never would have known the limits of the 8320a if I relied only on Genelec's "peak 107 dB" rating. I'm hoping the 8330a measure better because Genelec rates them at 110dB at 1m - fingers crossed!
