Google......what's that? Sounds like something you get in a third world country when you don't wash your hands. Oh.....it's the largest search engine ever??? Thanks DMF, you just answered my question in a positive and constructive manner!!!
I have stooped to sarcasm and I apologize to DMF and everyone else I may have offended, seriously. I checked google and did not find old references to 'ecoustics' and other mass purchasing sites helpful with knowledgable assessments of this sub.
I'll admit, between taking my son to football practice then cub scouts while shuffling my daughter to work I didn't have six hours to research every nook and cranny on the web about this sub. So I took the 'easy out' and decided to poll the generally qualified persons that I've come to trust on this site.
Again, if anyone has any input on this model I would greatly appreciate it. I am looking at a used model for the secondary system in the basement. Thanks.
