I get it. I have talked to Wendell and I was fully blown off. However they have been in business a long time and they do offer a good product for the price so it's hard to argue with that.
How did Wendell blow me off? My six-pac amps didn't play well with my MMGs. I had a buzz at one frequency but it wasn't a panel buzz, it was an amp/loudspeaker interaction that occurred right at the crossover point. He blew me off and said that's just that crossover BS talk (I never heard or read any of that). I used 3 different amps but only the six-pacs had the issue. No issue for me really I put them on another amp, problem solved but Wendell had no interest in my problem.
