This question is partly hypothetical. There are three pairs of speakers local to me, all in excellent condition electrically and cosmetically, all the same reasonable price. Each is a well-regarded three-way speaker: The ADS L710, the Dahlquist DQM9, and the Infinity Kappa 6. I would love to hear the community's thoughts on their relative merits. I have heard the L710 - used to own a pair - and they are ridiculously capable speakers. I also once had a pair of similar vintage 2-way Infinity, the RSe with a similar EMIT. I did a review of those a long while back, side by side against a pair of ADS L400 (large version). While I found the ADS much better balanced in the mid range, due I think to the crossover points on the drivers, I really liked the clarity and extension of the EMIT. I suspect that the Kappa 6 would not suffer the same mid-range gap as a three way. But I don't know. I have never heard any Dahlquists, but many good things about them. How would these compare in terms of sound, power requirements, listening levels, and capriciousness of placement?
