Here's the deal: If you're the kind of listener who must
listen to your stereo at levels that change the barometric pressure of your listening room, or if you can't enjoy reggae concerts because they don't have enough bass, then the ProAc Response 1S (revised) is definitely not the speaker for you. Read no further. Move on. Scoot.
Anybody left? Good. Now we can talk about a very special little speaker. In a way, I didn't even want to review the 1S. I mentioned to John Atkinson that I'd heard them at my buddy Ruben's house and enjoyed them immensely, but I'd been using a pair of $13,000 speakers to review an exotic amplifier and had, sad to say, become quite spoiled: bass down to 28Hz, 93dB sensitivity, and some of the most accurate soundstaging I'd ever heardwe're talking about some serious suffering for my art, here.
So when the ProAcs arrived at my house, I thought it unfair: unfair to me (I was gonna miss them big dogs), and unfair to the Response 1S. After all, does anyone remember who played after the Beatles on the Ed Sullivan Show?
