Yes, Boston Acoustics as a company pulled out from the Car Audio market some time back, so any products you see out there in any retail outlets are 'old' new stock. Once gone, they'll not be available and only way to get them would be second hand/used. There's plenty of other similar high quality brands of speakers out there which can and do sound just as good. The issue is that the Boston Acoustics were known to work 'well' with the oem audio setup/amplifier much like the BSW are. Other aftermarket speakers out there aren't as 'compatible' so you're really limited to BSW for new equipment if you *must* stick with the oem audio setup/modules/head unit, unless you can find some Boston Acoustics. There's probably one or two other speaker models from other brands which 'might' work well with oem audio, so maybe in various BMW forums, other's have posted up what they are/may be.
