as mush as your pocketbook will allow. I'm giving my 10's 900 watts each. should be interesting

It's enclosure dependent....you can make a box that makes them reach their mechanical max at probably 500 or 600 watts, but you can build a box that won't alow them to do this until they're getting over 1000.

yup, what swim said. basically:

big *** box=need less power

small box=need more power

this is of course, to reach xmax.

One thing to remember though, reaching xmax doesn't mean you are reaching full output.

When you have less power available, a smaller box can actually be louder than a larger one. You have to be able to pressurize the box properly, and the bigger the box -- the more power it takes to pressurize. Obvisouly there is a trade off at some point, but, xmax won't always gurantee you output.

To the original question -- 600 RMS is as low as I'd go per SX, I'd also use the smallest recommended ported box.

true, but in a lot of cases its easier to just tell someone to try and reach xmax with X ammount of power using X box. a lot of times, when people find out about all that can go into a system such as box design, power compression, this and that blah and blah they get intimidated. so IMO its just easier to say "reach xmax'. you are right tho, thats not all there is to it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Yeh, I hate when I complicate people lol. I think it would be good to tell people to get there sub to reach xmax, then add bricks to take up volume -- if it gets louder then good - permanently take up the space, if not, use the box as is.

Or, build a small ported box, and add pillow stuffing

Im also debating wether or not to get an SX,...I think of either the SX or SE, going to run in it on a jl 500/1, which is around 650-700watts rms, ported box of course.

 

[bamaboy 5,000+ posts]

is that at 2 ohms or 1 ohm? do jl amps go to 1 ohm?

Only in sealed boxes my friend, only in sealed...harder to compensate for the wrong size box when you're messing around with ported.
