Summary: paid alot of money for this sub after a year and a half it made a very loud noise (my wife thought a car hit the house)and that was that.All itt does now is hums very quietly...Im assuming the amp blew,i wish a would have paid extra for the warranty.
Summary: My one-star rating is about this unit's reliability. Mine started shorting and burning out mosfets after less than 300 hours of very light, low-driven use. I've written ML, and, while hopeful that they will make ammends, I am not holding my breath either. Too bad, because while the Dynamo was working, it made a fine compliment to my KEF monitors.
Summary: Purchased in 2010 to upgrade our Velodyne 8" that still works great to this day in my garage. Started making a loud humming noise a few weeks ago. Martin Logan wanted $100 to "look" at it out of warranty. For $70 I purchased a new Polk 10" here on Amazon that works fantastic and actually has more features than the Martin Logan, such as auto-sensing power on, L/R channel pass-thru w/ auto-crossover (if you don't have LFE output) and so on.
