cu. ft Question

[brs954 10+ year member]

If I buy 2 MA Audio ma120xe's and they are meant for a .75 to a 1.25 cu ft box and I have a 3 cu ft box for both (1.5 per sub) will this be alright? Or will this "Hurt" them?

that depends. If you want to have it louder and higher in bass frequency (Fs) then the smaller the bow the better. If you want it low and a little quieter then a bigger box is better.

ok that is what I wanted. But do you think that it will hurt the subs being over the 1.25 cu. ft.?

Nah, I don't think that'll hurt anything at all.

It'll just decrease both sub's powerhandling a litle. But it also will make them louder with a little less power.

I wouldnt run 2 speakers in the same sealed enclosure (sharing same airspace). If one goes bad the other will shortly follow.

If they arent ignore me>

Do you mean in terms of cone heating? Beceause otherwise nothing happens to power handling.

You know what?

I think that box will be PERFECT.

I don't think you are taking into consideration the displacement of both subs.

Yeah, after both the magnet and the basket of each sub take up their space, the box will be darn near perfect. Maybe off by like .05 or .07 per sub, and that shouldn't matter whatsoever.

Don't worry.

Just put 2x4s in your box to decrease the volume to what you need. Problem solved and subs are happy. //content.invisioncic.com/y282845/emoticons/peace.gif.2db28b618ed8d1964ebbe2f5021d2c39.gif

Ever heard of displacement limited power handling? Didn't think so. Look that up.

Passive radiators don't make use of much of a box's volume. The active driver won't survive too long if it's not meant for a large box.

Oops, what helotaxi said.
