Early in 2015 I started the process of possibly upgrading the four year old monitors I had in our 13x24 living room. As I listened to more and more speakers, it became obvious to me that I'd be happier with the floor standing speakers I'd auditioned. So my wife & and I came to the decision that I'd move the music audio system down to our family room (kids are adults, left the nest long ago), a 26x24 room, my new "man cave".
After months of auditions I ordered a pair of floor standing speakers that would have been way too large for our living room. But in that larger room, I "needed" more amplifier power, more sub woofer capability, etc.
Waiting for the sub woofers I ordered to arrive, I got the floor standing speakers and new electronics "dialed in" to the new room. When the subs arrived I had all sorts of troubles getting them to sound right in the "man cave", lots of standing waves and other annoying resonances. So I learned about bass traps and proceeded to install a half dozen or so of them.
While I was mounting the first of the bass traps my wife said that, recommending I move to the "man cave" that she "unleashed a monster".
Now that I have things the way I like, it's "all good".
