I agree with Barry on the ACA's being awfully polite sounding. The most joy I got out of them was building them lol.
To my ears, and in my system, they just have no guts down low, and even into the mid-range.
I used a pair as mono-blocks (16 watts each -8 Ohm) for a good while but to very little satisfaction.
I'm not sure its strictly a single ended or low power thing. Ive got an ANK kit-1 (300b tubes) that's only 8 watts per channel.....
and it thumps pretty good comparatively, more than the ACA's did,
but as you say not compared to a class d (Crown amp).
I also agree with wayne, it doesn't much matter with flanking subs in the system.
I've used flanking subs with my 4pi's and even now with my 7pi's.
In the later case they are strictly for deeper extension in the bottom octave or two (20-40, 40-80 Hz.)
Last night we enjoyed "Jurassic World fallen kingdom"..... I was reminded of the theater like sound and dynamics of a high sensitivity system like this...
it never fails to bring a smile.
