too big for sealed, too small for ported --> for IXL 18

[deucelee 0]

hey guys,

right now i got the box build already, it's a 11.2 cube box sealed. I was using a bunch of left over wood.

one IXL 18 is going to go into it. I could add (3) 4 inch ports and make it a 10.7-ish cube box tuned to 16hz, or I could keep it sealed.

it's going to get about 900rms.

what should i do?

I haven't ordered the sub yet. If I was to do sealed, i thought i'd go with the high Qt. I'm just afraid the 10.7 cubes is too small for ported, or will it be ok?

since sealed would be in such a big box, wouldn't the lows be comparable to the ported box? say in the 15-20hz? or not really?

If its the deep lows you are trying to achieve and you have the box volume to do it, go ported.

I would port that also. Thats a huge freakin box man.

Definitely port it. You may not need 900W. Mine's getting 600W in a 16 cube box tuned to 11Hz... it does very well like that. I'm afraid it'll bottom out if I give it more. Rattles everything in the house... I love it.

Only problem is, I want to build another one and my wallet won't let me.

that's the sad part, my box is much smaller then yours..., i wish it was bigger...

i was saying (1) IXL 18 to keep things simple, but i'll confess, i'm planning on using (2) with a EP2500, realistically i believe they put out 800-900rms at a 2 ohm load to each channel...another problem that could arise with that is if the amp can take that kind of load 2-3hrs, 3-4x a week...

i was told the v.2 versions of the IXL's were suppose to be able to take more power...if that's the case, do you guys think i should be ok then? with the EP2500 on a pair?

Don't worry too much about the EP2500... it should be fine with that. I'm no fan of Behringer, but the QSC RMX-2450 it's a copy of is a good design. I'm using an RMX-1850HD myself bought used from a pro audio acquaintance of mine from Saskatoon. I can't heat that thing up at all with just one of these subs.

16Hz is still plenty low. To be honest, I can't even enjoy content much below 16Hz myself due to the room I have mine in. I can't hear it, and all it does is shake the rest of the house.

cool man, i think i'll just go that route...(3) 4" ports per box its going to be then...thanks

yup, do it.
