Okay I talked to someone in diamond today... and they said they are replacing The tdx's with a d9 subwoofer.. but its gonna be the same except for the cone color is gonna be black.. and its gonna be made out of another material.. but i cant find any info about it online.. and the reason i know its gonna be replaced is because my tdx just failed me and i am getting a d9 as a replacement.. on the 28th... so if you know anything, let me in on it. thanks. (oh hey and if you wanna hear what happened at street stuff a diamond retailer just ask.. i finally got that shi* settled.. jonathon you might remember what happened.. )
