and its an ebay prefab box that i modded. knocked out the L part of the ports to give it a one db gain and tuned it from 40 to 52 htz. resined the insided and out and painted the box for better looks. the carpet pics of the box is right before i ripped it out and worked on the box. so its a modded prefab box made to be a burp box for spl. not music box at all really. so stop doubting and either buy them or look somewhere else. i rarely sell on here so im tryin to get rid of these quick to get my finals setup for this season
