It's great to see people are testing out bass traps a little more.

You can spend literally THOUSANDS on source components and speakers BUT if the rooms not right you're simply wasting money. Just 1-2K would fully kit out any room to the MAX and have it sounds phenomenally better.

I could not believe the increase in sound quality when I installed 13 of them into my small room and that only cost be about 1100GBP.

Best money I have ever spent!
