Yes, but all the bass traps I have seen are ugly and would not pass the WAF test. First Reflection points? Where are they? The coffee table, the end tables, the back wall? And to add to the problem there are a lot of people selling these room mods, frames stuffed with fabric, for a lot of money. Which means that you have to do a DIY, which then complicates the problem further, which is why no one does it.
