I'm curious what I'd be getting as well. Is there any use for this info? I know Nick mentioned a bit but I'm not sure how I'd interperate the info....if I want it louder I just get bigger equipment right?
What is the typical spl at a show? (Phish, WSP, DMB, moe., etc.......)
You interpret it by knowing how loud you like it, and how well your gear performs at that volume.
for example, a 50wpc amp is going to have a hard time driving 87db speakers to something like a loud concert volume.
a loud concert volume is in the 100-120db range.
SPL measurements i've done at stage lip for bands like Garaj Mahal or SKB have been in this area with peaks hitting above 120db.
that is fuckin'-A loud.
