anyone here got a pro box? does it really double ur bass like i hear ppl say?

 

No. Not even close.

That all depends on the sub you use, whether or not its in the proper size enclosure and how its powered and how many youre using. So long as the box has the proper interior volume and is solid enough not to flex, it doesnt matter WHO built the box.

 

i got a jl 500 withone solobaric L7. plz help me out, hope i didn waste my money on da box

 

The sub will work best in a specific enclosure with a specific amount of interior volume.

Check the subs owners manual to find out what yours is. If the interior volume of the box is within the recommended specs of the sub, and its built well (i.e. not plastic) then it will work fine.

 

oh okay i got it, thanks a lot
