Well, CV went out with my high school years (more than 50 ago); silk purse out of a sow's ear, if you think you're going to fix their shortcomings.
Buy or stay with?
I'm playing 2 Yamaha m40 amplifiers I have cerwin xls28 4 of them . I was thinking about buying newer amps like bryston 4bst amp Yamaha MX 800 it seems that these speakers are asking for straight power if my amps are not tuned up the woofers don't move what should I do or any ideas
