Speaker Cabinet Frequency Response

[selloutrr]

I know it's got so many varriables temp, wattage, materails, humidity, if your girlfriends mad at you, the last time you changed your strings, what color your shirt is, passive active, how loud, how efficient the speaker is, box material, covering, ply/solid, the room, isolated or on the floor. But maybe this would be a quick fix to your Hi Fi debate.

Eminence speakers used to or may still have a cabinet design software that you can download and design your cabinet to a speakers response, depending on the speaker you set the box volume it'll tell you the frequency curve it would produce. I downloaded it maybe 4 years ago it was interesting but i wasn't building at the time so i might have erased it. If it's not still on the sight i'll be home in a week i'l find it and send you a copy.

I mix my 2x10 Emi 105 8ohm sealed cab with a 1x12 G-1265 8ohm open back cab (4ohm load together) and mix them through a Bluetube stereo mic pre-amp. Each has a Sennheiser e609 mic on it. A little heavier on the 10s is a whole different sound than a little heavier on the 12 - but they are both better when played together.

The head is a D'Lite 22/33 ... so it has it's own sound but I'd say the Emis have a bit of a Fender-ish tone while the Celestion has a bit of the Brit-ish tone. But again just a hint.

I really like the feel they have when blended like this. It's all good.

That's it. Except my setup is the opposite of yours, the 2 x 10" is open back and the 1 x 12" is closed back. Close mic'ed w/ SM57s and mixed to taste at the board.

The 1058s are 8 ohms, the 10516s are 16 ohms for those who didn't get that part. If I were to try to describe the tone I'd say really good mid '60s C10Rs but perhaps more agressive. A good compromise between straight U.S. vintage tone and British vintage tone. I use them in everything. The 1058s work great in mid-'60s Supers.

I used to be a purist. I'd look inside an old Twin for instance and there would be one JBL and one Altec, I'd think, "Aha! The guy blew one of his JBLs". It seemed to me like the guy couldn't find another D120 or he was too broke to buy another Altec. Since then I've come around to the mixed speakers camp, that's where the tone is.

Another example: I have an old Ampeg Porto-Flex cabinet with a 15". I used to think that thing sounded cool as an extension speaker cabinet for a Twin with JBLs but the JBLs were louder than the 15". The old 15" can't be any louder than 95db 1w/1m, probably less, while the JBLs are over 100. (I should have tracked down a D130.) The Emi 105s are up around 100 which means they'll keep up with Celestions.

I'm also a luthier. I like building boxes because I can see and hear results much quicker than waiting for French polish to dry. I tap tune and tweak. I haven't kept track but I've built several hundred musical instrument cabinets buy now. I've settled on a couple well tested (by me) configurations that sound great. After the first couple hundred I know what to do to achieve predictable results.
