Having had a pair of CVs (different model) a long time ago (like 30 years ago! yow!), I tend to agree with that they can get loud and sound decent, but I never got another pair either. There are just better speakers generally. But for big relatively sensitive speakers, they can be useful to you perhaps. Are you sure they are functioning well, decent condition, etc?
What's your setup now?
Possibly you could recoup the price and sell them if you don't like them? Maybe do some more research on actual sales prices on used pairs first....
