I've had the pleasure of hearing the 2s, 3s and 4s with a variety of amps and cables. I don't have a clue what Jtinn is talking about when he says they lack detail. My experience has been that they have boatloads of detail, and in some systems it may in fact be a detriment. They love warm, higher powered amps and copper cables. Silver cables and strident solid-state amps caused considerable "shout" that is frequently heard with horns. Higher-powered tube amps really make bass in the 2s and 4s come alive with detail and dynamics. I found the bass in the 3s to be too punchy and not nearly as refined. As for differences between the 2s and 4s, the 2s are identical to the 4s with the exception of a second woofer and a larger cabinet. The bass response of the 4s may be too much in smaller rooms as the second woofer and larger cabinet really make a difference. I found the 4s to be about right in my 15' x 35' listening room (8' to 16' high ceiling). I also heard the 2s in a 14' x 18' (8' ceiling) and they sounded very similar in terms of bass detail. As for the mid range and highs, I can honestly say I've never heard speakers sound so realistic. The attack and decay of cymbals and piano notes are exceptional, and the texture portrayed in saxophone music is amazing. It's a matching game with all speakers and the Zingalis are exceptional sounding when paired with complimentary components.
