Hi Bob, I was a dealer for this product for quite some time and still have a set left. They are still the best thing available (imho) especially @ under $15K. They do however take quite a bit of set up and sometimes require resetting the internal switches in the x-over. Mike was probably referring to us as we are always futzing around with the settings. Generally the manufacturer charges a substantial amount to set them up (1 - 2$K). If you do purchase them we have a manual available to guide you through set up. Also be prepared for shipping hassles these units are large and need to be palletized when shipped. Good Luck and enjoy!
