The SB3000 looks tiny in comparison, no wonder they are so popular for integrating into smaller spaces and rooms.
I was thinking about changing my PC-2000 for a PB-3000 but they are so deep it would have to face the TV unit and not out into the room although there would be a decent gap between them.
I also came across the review of the PSA S1512 on here, that looks like a huge performer in a small box, I think you had the S1500 ?. That took me to the PSA V1512 but it’s obviously much taller than the sealed unit. I can only accommodate 1 sub unless I do some diy and a new floor, I’ve kinda forgotten about the PC 2000 in the front left corner, I don’t play movies that loud but enjoy the very low frequencies it can go down to on the occasional movie.
Im using a couple of these black rugs, they have a rubber type backing so don’t slip on wood or laminate floors and for the money not to bad quality, a few different sizes too.
