The Matrix series, as well as all 800 series since 1974, use the Kevlar mid.
Difference in B&W sound
Greetings, I have a set of 804n & 803 Matrix2. I'm running a Pioneer Elite 74 Txvi with a parasound 2003 MOD & a Parasound 5250v2. the 804 have a sensitivity of 90db. & the 803s have 89db. The Matrix sound so much better, so why would this be for an older model? Could the 1db. be that much of a difference? I'm confused.
