I have been looking for a set of ADS L1290 Speakers to match up with my Luxman R-117 for a while and not much in the Chicago area. I have read a lot about how good the 1290s are so it seems they are a good bang for your buck and keepers for most people. I have run across someone selling the ADS M15s and really do not know much about them. It seems as though the cabinets are the same as the 1290s but the drivers all seem to be different, especially the midrange and tweeter. Everyone on here has always been very helpful with more knowledge on these speakers than me. Any opinions on the M15 compared to the L1290, there is also a set of L910s for sale locally but I prefer the towers? Also what would be a good price for the M15s in good condition. I will be using these to replace my Dahlquist DQM-9c speakers as they never seemed to be a great match with the R-117 although they sound good I prefer a larger speaker. Thanks for all your opinions.
