View Full Version : 18" RE SX, ported or sealed?

Well, im switchin my substage out to (hopefully) 2 18" RE SX's, if i can find another. Anyways, im trying to decide whether it would be best to go ported or sealed with these. The box will be in the bed of my truck firing into the cabin, so space really isnt an issue. I just dont know if i should go a large sealed box, or a big ol ported box with the subs firing downward at an angle instead of straight into the back seats.

Ported for shure LOL. I wouldnt even think bout a sealed box. I think RE dosent even recomend using a sealed box.

no question go ported and you wont regret it.. i have mine @35 hz and it slams and hits the lows beautifully

Ported, but you gonna need like 14 cubes net. Plus port, wood, and woofer displacement. There goes your bed. Should be loud, though.

14 cubes eh? jesus, lol. There goes about half my bed hehe. It will totally be worth it though. The only thing i ever haul is bags back and forth from college for me and friends.

could i get away with like 12 cubes? i thought the reccomended max for these subs was 6 cubes a piece.

with the QTS that sub has it is well suited in a ported encloser vs a sealed and SX 18's play very nicely in 7-9cubes

14 cubes @ 34hz it is. Should i just do one giant *** box with lots of bracing, or will there be benefits from two 7cu ft enclosures built into one box?

I think the box is going to have a slanted face, so the subs fire down at a 45" angle or so, instead of straight into the rear seats, the port will be on the bottom of the box firing into the cabin as well.
