Brighton is quite a cool place. I did quite a few Jump Jive gigs there last year. Place really rocks when it wants to..
actually sounds like a cool place ..... I just did a quick google to find some unusual region in Britain as a reply to the 'simultaneously everywhere' remark.Brighton is quite a cool place. I did quite a few Jump Jive gigs there last year. Place really rocks when it wants to..
I've been to Brighton once.. unintentionally.
Took the wrong train out of Portsmouth.

Brighton has the reputation for being the gay capital of the UK. It was once just an elephants graveyard now it is a really cool place to spend a few days or if you want a relaxed and culturally diverse life it is a good place to head for regardless of anything else. I like the place but it will never be the centre of the universe.
I hate to break up the back and forth going on about Brighton, but I'ma sneak in real quick to answer the OP. xD
The way I understand it, it's kinda an ego thing. The guitarists want a big ol' cabinet so it looks cool. That's how my live sound teacher explained it to me.
I mean, because of the way four 12" speakers couple, you can get that thing throwing out frequencies below 20Hz. You'll never need that on a guitar. Not to mention a 12" can't get the kind of high frequency response a 10" can (and when you throw 4 of those together, you're still getting down to like, 25-30Hz from the speakers coupling).
Personally, I prefer 10" drivers for guitar as opposed to 12" for this exact reason. It just doesn't make sense why you'd give up the high frequency response that can give you more bite and whatnot to get a lower response that you won't ever reach with a guitar.
right ..... you can just look at the specs. Some 15's like a JBL D130 goes just as high as any 12 or even higher than some.Interesting. It's been a long while since my SuperReverb, but I've never felt highs lacking on 12's (regular drivers or the d-120's or 130's.
I do understand that a speaker and cab combination's size does effect the size and heft' of its sound. That can come into play as far as a cab's size being a better fit for the room you're in
add.. As far as highs' go-- I'd say the tone of those highs (speaker choice..), and the beaming/uneven coverage are way in front of cone size
My bad. I should have been thinking 15" not 18 -but I just tried it again and it looks like I'd still be off. With 4- 7's vs a single '14' they both come in at about 154sq in. (does that compensate for the suspension ok?"4-10's have more surface area than an 18"
Not so. If you calculate for EFFECTIVE area a 15 comes out at 154sq ins and 4 x10 at 115sq ins. That is allowing for the lost area due to the suspension. Naturally different speaker constructions will change this a bit but generally a 15 is a bigger "cone" than 4 10s. The latter might well have a much greater total power handling capacity tho' and at least the same displacement so they might well go louder, cleaner. ..

Wow ok that's wild. So they're using 8.3 inches dia for a 'ten, but only about 13 for the '15".I think the math is off a little here, or some incorrect assumptions.
Looking at the Eminence website for their bass speakers, the surface cone area for the Legend BP102-4 is 345 sq cm x 4 which is 1380 sq cm for a 4x10. And the Legend CB15 has 856 sq cm of area. 4x10's have more surface area.

(If I didn't screw that up- Making my way to metric 'round here.. inch by inch
Incorrect assumptions my bandanered friend.
But hey, you got 'yer Dr Who goin there.. That 'be an Ok in my bookIncorrect assumptions my bandanered friend. Well, wrongly remembered dimensions.
You are perfectly correct.
