You can't have too many bass traps...

Good advise given already.

First you have to define what a bass trap is, to answer the question. If a "bass trap" reduces 60hz by 5% of what's needed but reduces 30% of 2k level, then what would happen to your sound after installing the 20 bass traps you need for the 60hz? "Bass trap" is a tool. Use the right tool for the job.

Bass traps are actually not the right tool for 60 Hz.

Well, that's why in my original post I said one needs to define what a bass trap is. Generally speaking, people buy "Bass traps" to tame all that low  bass output. Whether they are right or wrong, that's what people do.....
