Hello everyone I am selling both of my Martin Logan subwoofers Dynamo 500 10. Both subwoofers will come with a high quality audio quest red irish cable worth $100 each see photo of catalog. Only one subwoofer works the one with the blue light in the photo. I think the other one might be a quick fix. Pricing for 1 and getting the other one free basically. The bass is insane on these things! Enjoy! Please beaware you are purchasing this knowing one will need some work even one hits super hard!

One Martin Logan Dynamo 500 powered subwoofer. Being sold as is for Parts/Repair. It is in excellent almost pristine cosmetic condition. However upon powering up it buzzes and hums. I don’t have the time to diagnose and fix it so therefore it is a parts only item.

For sale is a MartinLogan DYNAMO 500 High Performance Subwoofer System Black. It was fully tested and it works and sounds good. The driver is strong and has great bass. Please closely asses the photos for condition and message me with any questions prior to purchasing. Flat rate shipping in the continental United States only. No shipping to PO Boxes.
