Ever wondered why your cab has funny shaped holes in it?

I'm just going to get myself a degree in mechanical engineering and acoustics ... back in a minute.

Nope

I thought it was so the sound could come out and then I could hear it

I tried reading that - - but I fell asleep I'm glad he cares though

Can anything be added in teh impedance section about how that relates to valve amps with output transformers? There is stuff about peaky impedance loads being hard on them, but good information is not so easy to come by.

I care about port, too.

For the opposite reason a toilet seat has a hole in it.

wow. A thought did strike me though.... If I ever played a gig at the top of a high mountain my drivers would be likely to break (or whatever fancy word alex uses) at lower volume than if i played by the dead sea...

On the top of Everest the cab would be quieter and the bass response thinner. The treble extension from the woofers would be increased too. The thermal power handling would be about 25% greater. However, your bass playing would suffer a lot more than the cab at that altitude!

Or solar power?

More on the air front, guitar lead to be at a low enough altitude.
