I am having the same problem, i.e. identifying exactly what product I have. I know it is an older (10 yrs?) 10 subwoofer but there is NO model number on the back. A photo is attached. The only numbers that appear are: (not all same area) LR106476...or T.2.OAl 250V and 120-60 mhz 2.0A I assume it is the first but the website provides no information on that number. The manual that came with it only says "Synergy"...no other model numbers are evident. This has been a great Sub but has recently developed a sputter...suggesting a cone is going or gone. My question is whether or not a sub of this type is worth repairing or should I be grateful for the years of use and move on! It's a heavy sucker...that's for sure. Any help would be appreciated.
