Yes, this is an excellent speaker, comparable to many in the $1000-$2000 range, I kid you not. This particular model is developed by Infinity using the direct research of Floyd Toole and the performance of these speakers was verified using double blinded tests with many trained listeners against competing speakers.
However, as Seth stated, they are resonant, as are most speakers. If you were to modify them to specific point, which don't mistake, is a lot of work, they would easily compare to speakers costing 50x the price, in objective performance. The drivers and crossovers are of appropriate quality; the only shortcoming is the cabinet system used. These don't even use proper internal acoustic absorption, much less a proper cabinet. But a proper cabinet is not economically feasible on low or even medium price range speakers.
I have experimented with the Primus 160, a 2 way version of the speaker above, and the results were beyond my expectation when a highly modified cabinet and active DSP xover was used. It uses 1st rate midrange units and a very good tweeter. Also, I have measured/analyzed the midrange used in the Primus 360(the almost identical 2005 version of the 362) and it was of 1st rate performance. I also do modifications for people to existing speakers to radically improve performance, but this is not a cheap service - it's very labor intensive - and since I do it only a few hours in a week(I only do it on weekends, a few hours a day) - it takes a few weeks for me to complete a modification for someone.
If I had a local Fry's, heck, I would pick up a pair of the 362's at this price just to modify and give away to a friend or something. But the shipping of almost 1 C note is puts it over what I want to spend just to play with it. But for someone needing some speakers in the 1k range, these are an excellent choice, and at the current price, it's a steal of a deal.
Please look at the measurements from Stereophile of the Primus 360:
