Well today I wanted to impress my wife by showing her how amazing the CM1's sound when running as mains. I hooked them up and noticed something didn't sound right.. almost like a tweeter wasn't working. After some troubleshooting I realized the left tweeter wasn't working. I took the speakers apart and swapped tweeters with the other good working speaker and it still didn't work. hmmmm.. so I busted open the ohm meter and started doing continuity tests from the rear jumpers to the tweeter wiring and was getting nothing. So I popped out the crossover and this is what I found (see picture). Both the positive terminal wiring for the low and high was falling off the connectors. The tweeter wire was completely off while the bass driver was just barely touching. Talk about a quality control issue on a set of 1k speakers. Unbelievable! I think this will be my final set of new B&W speakers that are made in China. I even had trouble with my CM9's(both mid bass drivers quit working), 683's (dead bass driver) and now this with the CM1's. I gotta be honest I have had cars that were more reliable..
I have had lots and lots of B&W speakers over the years, CDM, older 600 series, Nautilus 8xx, and even had a pair of the 300 series, not once did I ever have an issue with any of them. If memory serves me right all of these speakers were still made in England at the time. unfortunately times are changing and everything is about making it as cheap as possible and squeezing out that extra profit. I honestly believe the made in china speakers are inferior in terms of build quality compared to there older counterparts. Bummer..
