Walker,
I haven't seen or heard any Cerwin-Vega speakers in over 20 years. Their reputation (back in the day) was that of being great Rock-n-Roll speakers but with limited finesse. However, I always thought they sounded better than what the audio-snob crowd gave them credit for. Of course, "dynamics" is higher on my list of priorities than a lot of folks (my second system back in 1977 was built around large 3-way horn speakers).
Honestly, if you are getting a good deal on these speakers and you really like how they sound, this is a no-brainer. Buy them; put them in your system; try them out for a couple of months. If, at that point, the luster has worn off, and you no longer like how they fit - dump them. It's unlikely you will lose much money in the process.
Good luck,
Kevin
