Up for sale is a beautiful example of a Martin Logan Dynamo 500 High Definition Subwoofer. This unit is from the original adult owner. He used it in a two channel system. Im my opinion it is in NEAR MINT cosmetic condition but please look at all pictures and judge for yourself. I have personally tested this unit and found it in good working condition. When turned off it makes a thump sound as many of these subs do. Included with the sale is the original Owner's Manual.
