7 cubic feet, 7000 watts, need subs!

[Ryan shaw 10+ year member]

So i have 2 boxes each with 7 cubic feet net tuned to 30 hz with either an 80 sq " port or 2 6" aeros, and an SD 8000.1 to power some subs. but i need subs! I want some decent sound quality but more importantly some low, deep, car shaking bass. Something that will dominate the lows

So far i've been looking at these:

xcons

axis's

lms-r

lms 5400

Q's

I cant think of anything else to look into, I've used all but the xcons , but none were mine so I got very limited listening time. Just looking for some more insight on the build, thanks!

So wait you have 2 different boxes and they both are 7 cubes is that before or after sub and port displacement.

net= after displacement

i would go with a pair of 18s 5400's thats about the only subs that would be comfortable on that kinda power...

I'd do quad 15's if you have enough space to mount them. What's your budget?

Around 2000 bucks. I have 1000 right now so gonna get one, then double it up when I get the money.

I was leaning towards the 5400's, then thought maybe 4 axis's would out displace them due to an advantage in cone area. In winds the 4 15" xcons modeled best actually but who knows

2 6'' aeros doesnt sound like nearly enough port area for 7 cubes.

5400s

2 6'' aeros doesnt sound like nearly enough port area for 7 cubes.

2 6" aeros has around 90 sq inches of port area if I'm not mistaken?

Would love to, nearly impossible to find though //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

about 57" of port area.i use 2 6" aeros in my 7.2 cube box

ya but with the flares it makes the effective area similar to an 8" port for air velocity right?

Xcons are pure beasts. 38mm xmax and can handle a good amount of power.

Xcons are pure beasts. 38mm xmax and can handle a good amount of power.

SSA says they have 31mm of xmax, do they underrate? I know the xmax limits on the TC Subs are rated very conservatively. Axis xmech is actually near 41mm and the 5400 is near 50mm. From my experience, higher xmax means louder low bass. I'm sure this isnt always the case but from my experience it generally is.

I'm also thinking 2 axis's are gonna out do a single 5400, though I know with the right power 5400's are nearly untouchable
