**Q: Has anyone listened to both this and the svs pb16? i've seen the numbers but i'm curious how they compare in real life.**
A: Yes but in two different rooms so it didn't compare. My buddy has two of these in a 17 x 15 and it pressurized the crap out of the room. they hit every note which is very surprising. I have two of the normal monolith 15s in my theater now and was running HSU flagship before and I can tell you that I monoliths hold notes better and dig much much deeper.
