Thick carpet with thick underlay is absolutely the best! The shortest dimension is usually the height. A carpet is absolutely the most important thing in any room.If you can't do at least a third to half the room in carpet then get a big rug and roll it out when you listen.
Room Question
I had a pipe break and my basement flooded. My equipment is okay and my speakers were up on spikes. I have to replace the carpet. Is carpet the best thing for sound in rooms or is there some other options I should look at for my flooring? Thanks
