Not a very constructive remark Jez.
I do however agree that the use of sound level meters, and the interpretation of the measurements made, is not for the noviciate.
I have 'played' around with a Maplin SPL meter - I found it of doubtful accuracy and limited to frequencies < 5kHz. But for what its worth when set up 4.2m away from the centre line between my speakers (Quad 57s) and at a height of 0.75m (level with my ears when sat in my chair), I obtained the following figures: -
Speech at normal conversation level: 55 - 60dBA
Late night listening (= '6' volume setting on a Quad 44): 60-70dBA
"Belting it out" (= '10' volume setting on Quad 44): 70-80dBA
"Shaking the floorboards" (= '14' volume setting) ~ 85-90dBA

Add in the directionality versus frequency, power handling versus frequency, power handling versus time, the inverse square law applying to sound from a point source (or approximating a point source) and the differing reflectivity/absorption of rooms and I think we could say that gauging safe power handling for a speaker using a SPL meter would be pretty useless...
The best protection I know of is that once used by KEF in their "S-Stop" technique. I believe B&W had something similar....

Well I like to play at a decent volume and I've never blown or damaged a speaker in 30 odd years so it can't be that easy to do.
Current Lash Up:
TEAC VRDS 701T > Sony TAE1000ESD > Krell KSA50S > JM Labs Focal Electra 926.
yes why of course ?
Not sure just never consider headphones as an option and assume that much use would further damage my hearing
I just like speakers and the way noise comes at you and washes over you I think listening with the whole body is better than just using ears

I'm Patrick.
I certainly enjoy listening to music on headphones however I do ultimately think it's best enjoyed from a
good set of speakers. Isn't music itself performed aloud?

"I'm aware of the concepts and consider them hugely over rated actually. Have you heard of the concept of knowing what you are talking about before posting myth as fact? "
Yes AE, the first part is fairly evident now I think about it.
I stand by what I said, and I do analyse my thought processes not only in electronics, but in all else.
With a manufacturer's specified maximum spl O/P for a speaker, an spl meter is of use in knowing whether or not one is approaching the maximum limit of I/P power to a speaker.
I have formed the impression that you overate yourself and also are rude.
Dennis. I'd suggest you and Jez 'debate' this no further. Thanks.
It is impossible for anything digital to sound analogue, because it isn't analogue!
