Marantz PM6005 has 45 watt rms in 8ohm, lets say 50 watt peak, that's 17 db, with 87 db sensitive speakers (i guess they measures it in pairs) in 8 ohm i should be able to play 104 db (actually a bit more since i only set the peak power to 50 watt).
Playing AC/DC Dirty Deeds Done Dirt Cheap from youtube, the volume at 10'o clock using Sound Meter and my samsung note 3.
2 feet away from my speakers i get around 75 db, my phone directly on the front grill i get 90 db. Shouldn't i be playing alot more then 2 watt,even more then 4 watt (in theory it should be 93db with 4 watt)
Why this huge difference in spl?
When they measure speaker sensitivity do they do it 2-4 feet away or a few inches from the speakers?
Why am i only playing 75/90db, it's pretty loud already, in fact so loud i can't imagine going from 90 db to 104db, (with my phone on the grill), since it must be insanly loud (have been to concerts with spl above 100db) and i imagine theres alot of distortion, although there shouldn't be any (atleast not much)
With earplugs (-22db) i couldn't get spl up to more then 92 db with my phone on the grill
Is the app limied to just a bit more then 90 db or is it the mic on my note 3 that limiteds the max spl i can measure?
