Excellent Enclosure

I've had this enclosure for a few months and it's still rock solid. Makes my kicker sound amazing and it's something I would highly suggest buying if you're in the market for a box.

Good box!

I've had this box for about a year and a half and have to say I'm very pleased with it so far, felt and still feels very sturdy, no "squeaks" when my L7 hits which is more than I can say for the last box I had. Good to go!

Whoa!

This is the box to buy if you have an L5 or L7. Having this box and sub combination will make you want to turn your music down. If you dont have the right amp you will not have the pleasure of hearing your neighbors telling you, "can you turn your music down." I have an Mtx 7402 amp(about 600Rms @ 2ohms bridged) going to my L5 in this box and I dont even have the amp turned up all the way. So if you have an L5 or L7 and a good amp go with this box. The box look big and is long but it is still small enough to fit in my Dodge Neon.

Nice box.

Bought this box to go with a square Hifonics Brutus and it had done a great job. Good construction and it creates real deep loud bass. Very pleased
