Based on information obtained in this forum, I have started building the framing for my stage that will hold my 55" Projection TV, front speakers, and subwoofer. As I plan to complete this in the very near future I need to ask a couple questions. I want the cablesspeaker wire totally hidden and for them to come up through the stage at the location where they will be needed. The stage will be filled with insulation and the flooring will be 1.5" of MDF. I will be carpeting the stage once it is complete. So now with the questions. Does it matter what type of carpet I use? Plush? Berber? Indoor/Outdoor? Basically concerned about getting the best sound. How should I bring the cables up through the flooring? Just drill holes through carpetingfloor? Wall Plates? Thanks for any help on these questions.
