I replaced 1 pair with the sonance VP88R and used the square adapters. They are pretty amazing

It was a super close fit due to the bigger size of the monitors.. I just need to pony up the money to replace the other 2 prs. I hate them so much I don't even turn them on

I am using 3 of them for surrounds and they are great but aren't required to play bass.

My thought is to move the sonance to one room and then either try out the Martin Logan vanquish or??? I dunno. The sonance are great but expensive so it's just deciding what do to with my main entertaining area that has 2 prs of speakers that need to be replaced
