I have had to replace all 4 of my drivers over the last few years on my PSBs. The cones were ripped. Why may that be? I play them loudly fairly often (sometimes a few times a month for a couple hours), which in this case, means dialing the pre-amp to about 50% of capacity. I have lived with the system in Miami, Fl (10 years), Oklahoma (3 years), and Gainesville, FL 10 years). I have to say, I know little about audio, but i like to listen to music.
My components are:
PSB Stratus Silver - bought new in about '90
Aragon 8008 MKII - bought used in about 2005
Acurus LSII - bought used in about 2003
Audio Alchemy CD Player w a DDE 1.1 - bought new in about '90
and i use Nordost Supreme Reference with bi-wires (last 5 years, Monsters prior) from Aragon to PSBs.
