I have had the cv for many years, outstanding...exept for when going really loud I mean loud they want to cut out.... they are 4ohm. and are going through my kenwood kc-x1 km-x1..system is 8-16 ohms. both system and speakers have been in the shop... could not find anything wrong...but said how loud do you need to hear them. lol any way I just got the chours 2 they are 8 ohms, and they sound amazing.. different bass but don't cut out... ideas on what to keep, iam sure its a matter of the music you like to hear... juts looking for thoughts thanks,,,
