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!

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
