They don't tell us what the Woofers are used on the SS8, just dual 8", with the Accuton and the Raal; vs the single Satori 9.5", AT Mid, and Satori Be Tweet.
Other than that, the 8 is a 4 ohm design, 86dB sensitivity, and he recommends 100w amplification. the 9.5 is 6 ohm, 87dB sensitivity, and 150w.
At the end of the day, if I were buying new, it would be 5 ea 9.5s for my bed layer.
But back to my point, and knowing Dennis’ voicing and XOs... I think these two will sound more similar than not.
And for this Cat’s asking price of $4350, I think
@Pogre should drive over and audition these at the very least!
