What makes an 8x10 do what it does?

Here's your answer ......

Eminence Kappa Lite 3015s. 15" drivers. It & the Faital Pro 15PR400 rule the roost for full-range 15s. True super drivers.

The speaker.

The classic sealed 810 has high efficiency and sensitivity because of the type of speaker used and because there are 8 of them.

A classic 810 doesn't do much below 80Hz. There is a peak at about 200Hz. In other words, they spew mid bass giving the illusion of huge low end.

The drivers are vertically aligned, so an 810 projects well.

The speaker is critical for good sounding distortion/overdrive for guitar or bass. The speakers used in a classic 810 are more akin to electric guitar speakers than PA speakers. This also means that the speakers have good treble response without being harsh sounding.

Once again, the speaker.

-having eight drivers all doing the same thing, with no frequency gaps needing to be crossed over, creates a very uniform response;

-the sealed chambers and pairing of the speakers makes for a very "tight" and responsive feel

-the low-end roll-off. The cabinet does NOT produce any lows below (I think) 40hz. What it does produce are lots and lots of thick low-mid frequencies, and these tend to cut through best when one is fairly close; within 15' or so. Beyond that distance, the absent low end becomes quite apparent.

810's are great because they can cut through high stage volumes without interfering with the low end coming from the subs. With an 810, you always can hear yourself. You'll occupy a distinct frequency spectrum that works beautifully against high-volume guitars, but is nonetheless manageable for the sound person.

That's my $.02. They do something other designs do not.

Best most honest and objective response yet I think. Not that other rigs can't/don't sound great.. As stated earlier " why would anybody wan't to haul around a refridgerator" there must be a reason or nobody would. I think a Stingray through an SVT w/the 8x10 cab is potent for certain formulas.. I am playing a Jazz now and putting together a new rig. Wanted some current thoughts.. Appreciate all.

OK mathmatician. It's TECHANICALLY not the surface area. I cold try to impress a bunch of people i don't know by my higher than average I.Q. and my math skills but that wasn't the point.

I was useing it as a point of referance as to why the two options sound different. If you think surface area of a speaker doesn't make a difference then explain Phil Jones Bass amps. He uses a bunch of 5"s that make a extremely large surface area.

And I recommend trying walking away from your amp some time. You'll be surprised how different is sounds when you get to about 20 feet in front of it. A low E is about 41HZ and is about 27 feet to long so untill you start getting near this you're not hearing waht it really sounds like. There's a reason FOH decks are so far away from the speakers.

Being able to play does not make them audio engineers with an understanding of: phase issues, comb filtering, improper power distibution, etc (most of which you will find with that mixed setup).

+1, but problem is this is a subject that comes up again and again and degenerates into flame wars. You either read, listen, experiment, and learn or.......

I've made a New Year's resolution to not participate in the arguments anymore so I'll leave it at that and hope we can get back to the OP's original query of what makes 8-10s sound so special.

I think they do sound different, perhaps it's because you have 8 drivers that really aren't exactly identical in specs due to manufacturing tolerances, maybe those add and subtract the sound in a way a 2 or 3 or 4 driver system can't. No idea, just a quick and dirty hypothesis

Sounds like awesome in a box as far as I'm concerned. Must be weird science.

I have this exact setup (well, two 4x10 cabs instead of one 8x10), and it's hard to beat it for nearly all styles of music. A Precision Bass does well through an SVT/810 rig also.

Again, it's Vd & total Sensitivity that matter for potential loudness.

To a very significant degree, it's conditioning.

It is still NOT surface area, but sensitivity and displacement. A whole bunch of 5" speakers mean nothing without the combined displacement and the combined sensitivity to make good sound for bass.

There are some lightweight 8x10'' - cabs that sound reak fine, like my Tecamp L 810. It's only 86 lbs and has a sound you can lean against. I live it.

For smaller venues I prefer my SWR 2x12'' Workingman, upgradet with two Beyma neodymium speakers to 600 Watt @ 4 Ohm.

But there is no way for me to give my 810 a goof bye. I need it, and it makes me smile every time I use it.

that's to take into account the room interactions with the source signals, in this case the FOH speakers, not the actual source sound waves "developing" in and of themselves.

You do not need to have distance to let a low E "develop", otherwise you'd never hear it in headphones.

[mjac28]

I agree with that one guy...no not him but the other guy.

Uh, wow.

Because Ampeg 8x10s kick ass. Don't care why.
