all
just a quesiton or thought to ponder...I haven;t read the whole thread so sorry if someone already asked this.
I play in an indie rock band...not as loud as some full on metal or hardcore rock but loud enough imo!
I use a 300w Laney RBG500 1x15 combo which for smaller gigs (e.g. pubs) is fine. But I find I really need to add my 4x10 cab for the larger venues. (both have switchable horns)
Prior to this I had a 100w Trace Elliot Commando, which was woeful even in smaller venues. I tried all sorts of things, tilted it back, put it on a stool etc etc. but could hardly ever hear myself regardless of what was going on foh. I digged the tone, but it was wasted most of the time.
So for me I think its not so much about volume but the air that you can shift. I'm not aware that even with my cab I turn up the volume that much more (ok, maybe a bit then). There feels like there is plenty of headroom over the fender 2x10 and marshall tube amps the guitarists use (though they don't crank them to 11 fortuantely!)....what I mean is its about "feeling" the sound as much as "hearing" the sound...I like to feel my trouser material flap a little!
Maybe someone can explain this scientifically.....I can't!....is it total speaker surface area or something?
cheers

So much has to do with:
1) The honesty of the wattage rating by the manufacturer, which varies hugely! Also, the distortion/quality of the amp.... i.e. is it 100 watts at 5% THD, or 100 watts at 1%THD. Finally, regarding wattage, that level of low end roll-off impacts things (i.e., is the amp reproducing frequencies down to 30hz, or rolled off at 40hz or whatever).
2) The quality of the speaker (the whole xmax thing... SPL, etc.). One 15" speaker can be loud as heck through the midrange, and then totally break up when pushed, another 15" driver can THUNDER, but possibly require more wattage to get there.
3) Related to the above... appropriate tuning of the cabinet, which can really impact how a speaker punches versus booms, which is directly related to perceived volume.
I'm not qualified to explain things technically, but I've tried so many 'equally rated' cabs (SPL, tuning) and heads (wattage) that perform TOTALLY different, that I'm pretty comfortable saying that looking at published specs unfortunately doesn't tell you much.
IMO and lots of IME!
