I live for details.
I actually tried playing with the calcs for my own rooms in the past. The calcs are simplistic ...
sure they are simplistic ... but it's quick and gets you some ball park numbers ... So, just for fun
LFR880 SPL 92dB 1W/1 meter
SPL 1W @ 10ft (3.048meters)
= 92 - 20 log(3.048) = 82.32 db
SPL 180W @ 10ft
= 82.32 db + 10 log(180) = 104.87 db
Degrading (turning down the volume) so we don't clip dynamics (-15db) we have an SPL of 90db at 10 ft. So you can get a front row classical music experience without distortion but if you want rock concert levels your gonna have to move closer (and wear ear plugs
)
