I got this sub in June for my 18th birthday. This sub pounds hard and has great quality. The only thing is the glue they used to glue a price down will come apart once it gets cold over night and detach an then the sub won't work until u send it back to get new one or they fix it. Mine broke bout month and half ago and I have been trying to send it back to Re audio but they won't help on shipping and handling at all and it's 100+ to send it back when u has already spent a lot on the sub. The sub is great till it stopped working.
