Not bad at all

Definitely good for a sealed enclosure. If you can make a ported box big enough for the both of them, you can expect 3-6 dB more than that.

Very impressive off a new mic.

Nice score :thumbsup , I hit a 143 in a sealed box with my 2 12'' SExxx's off that same amp in the trunk of my maxima.

I hope this proves that I can do well with a single SX ported

do you consider these good numbers?

i'm curious as to what people expect to hit db wise. like what does the number mean to you? (this calls for a new thread )

Warren, for a sealed enclosure, those are very good numbers. He can make them a little higher if he uses sound deadener (if not already done) or upgrades his battery, alt, wiring, etc.

how are those good numbers for sealed.... is it b/c the average sealed boxes have those numbers or is it that the manuf. says that those are expected numbers?

Because compared to other comparable sealed enclosure setups that is a high db score.

i have done some sound deadening in the hatch area, not a very good job though. Im running all stinger interconnects and 1/0 power wire. I have a grounding kit hooked up too, stock battery. I didnt charge my battery up very good though so i can squeeze a few more out with that. Also my box has a leak around the sub thats hurting a bit. Once i port these and get a second jbl 1200.1 im sure ill hit 150 easy.

how much are you hitting with your 15", im thinking of getting some after the xxx's in an 8 cubic ft. box, does yours have good sq in that big box, o and i think for the 2 magnums in that sealed box that is a very reasonable score :thumbsup also how many cubic ft is your box burnboy

 

[Burnboy 10+ year member]

the box is about 4.5 cubes before displacement, not too big, also the sq is excellent event at those high volumes, it hits so precise its scarey
