I've had this sub for a bit, but barely have used it. Other than a few hours of play time, it is brand new. The cone has a very minor imperfection that needs to right light to see, otherwise everything is perfect. Excellent sub that gets very loud off little power, and can handle quite more...

Hi, i just picked up a 12" lms-4000 driver and i've been doing some modeling with winisd to try to find the "best" possible enclosure. My goal is to get clean and accurate sound down to about 20 Hz (maybe a little lower). spl isn't an important factor for me as i've got a new baby in the house...

Here is a custom TC Sounds 10" LMS4000 subwoofer we built a while ago, we are selling it on clearance as the customer has upgraded. The enclosure is 35Lnet, and made from solid 6061-T6 7/8" Thick Aluminum plate. Bolted together, and clear lacquered. It weighs in at 130lbs
