The 3 Pi Theater speakers by a vote of seven to five. Those who preferred the Pi speakers cited the warmer and deeper bass combined with a larger soundstage. Those who preferred the Seas speakers liked the clarity of the Seas woofer. Some felt the treble was too recessed, which surprised me because I find it almost too bright for my ears. I didn't vote, but if I had it would have been for the Pi speakers. Even at the moderate volume levels I find the Pi speakers are warm and non fatiguing over a long listening period. The bass is more extended and more powerful, but it is tightly controlled and not at all like the "wooly" bass I have heard with some real vintage speakers. The Seas have greater midrange resolution but they don't provide as much listening enjoyment. At higher volume levels the Pi's are the only choice.
