Martin Logan Grotto Servo Controlled Subwoofer -Good Cond.. Works when is plugged in Not really familiar with speakers but looks to be in great condition

Martin Logan Grotto i. This is a premium servo controlled sub. Great fine tune adjustments to seamlessly blend into any system. Whether you are looking for the addition to your 2 channel or upgrading the theater mode for multi channel. This sub works great as the day I got it. I have taken great care of bubba. Almost zero signs of being used other than a *tiny spot on the edge of the veneer on top, and a slight on the bottom front where the wife got too close with the vacuum. Ugh. But i went over it with a magic eraser and can barely see it. Check the photos. Ask any questions. It comes with the original box, and will be shipped in it, so be aware it has the manufacturer and model on outside. It is durable enough for shipping. That is how I received it. It comes with rubbet feet already attached and the spikes too in the box. Comes with power cord, and I am including an Audioquest Sub 1 3meter cable for connectivity. I am making room for 2 channel DIY projects. Need the space and money.
