Well I Still Have A BNIB 15" TC Sounds LMS 5400 Titainium Cone With Black Powder Coated Basket.... I had 2 of them and 2 sundown audio 3000 watt amps but never did get to hear them as I ran into money problems and got rid of everything... This is the only thing I have left from the system I was going to build... Considering its brand new and never even been powered what are you trying to get them for?
