I don’t think he know what he’s talking about.
The cabinets are no longer made of Corian though that’s what he said.
He make a huge deal about the tweeter and midrange sharing a common cable out of the crossover so that the tweeter has to go through a 220 mfd cap, which he po poo’s to no end. But when I look at the picture of the speaker’s backside, I see separate mid and high sets of cables out of the woofer cabinet. So why would he think the tweeter goes though the big cap?
He doesn’t know how Wilson does the woofers and didn’t bother to read the Stereophile article that clearly notes that both woofers are in parallel along with a 20 ohm resistor.
BTW, I put a 30 ohm resistor in parallel with the 18" JBL woofer of my speakers. It smooths out the response tremendously.
