Shuttle 3.0-8T Question

    Hey - Just got a Shuttle 175W 8" combo to make rock band practice easy, but I fear it won't cut it. My old 60 watt 15" combo was a beast to move, but it's a good deal louder than the Shuttle, though the Shuttle sounds much nicer.

    I read some FAQ sticky (though I can't find it now) that doubling your speakers makes loudness go up by a factor of four. Does this apply to speaker size as well? (I basically halved my speaker size and lost a lot of volume)

    Long story longer - if I buy a 8" extension cab, will my two 8" speakers equal a 16" speaker and then be as loud as my 15" speaker? - Thanks, McB

    There's a real limit on what an 8" speaker can do. If you need high volume you'd better look elsewhere IMO. I think it would take 4 - 8 inchers to get you in the ballpark of a 15" as far as speaker cone area. (please correct me if I'm wrong, somebody) Doubling your speakers gets you 3db.

    That being said, I love the sound of the little bugger.:)

    Several options. If it is possible to leave some gear at your rehearsal space, get a 15 cab and leave it there and use that as your extension.

    Othewise, what about running through your PA?
