I am extremely new to the audio world this journey began 6 months ago I've made a couple of mistakes like blowing the tweeters on my speakers and buying some equipment that I've since sold off . This is the wall that I created in my living room it's has a 2 ft bump out from the drywall with a hidden door to get to the back so I can manage all of the cables I cut out a square behind the TV as a bass trap and insulated the entire wall with roxo safe and sound and all the wood panels are insulated. The shelves are made out of epi hardwood and the Shelf under the TV is African mahogany
