Martin Logan Summit X Speakers High Gloss Black

For sale, we have a pair of Martin Logan Summit X speakers with the optional High Gloss Black finish. The speakers are in perfect working order, and they sound excellent. They have spent a considerable amount of time in our listening area. These Hybrid Electrostatic speakers incorporate two 10" woofers in each speaker in a sealed cabinet, driven by a 200 watt amplifier. There is nothing like electrostatic mids and highs, and the blending of the woofers in the Summit X is done very well. This is the first set of Summit X's that we have had come through our shop, and we have really enjoyed having them. 

Physically the speakers are in very good condition. Blemishes of note are, some swirl marks on the cabinets, which is typical with a high gloss finish, a mark on the back, left side of one cabinet, and a few very minor marks on the metal grills. With this being said, there are no dents or deep scratches on the speakers. They have been well cared for, and present themselves extremely well. Please see the many pictures in the listing for further details. 

Unfortunately, we don't have the original boxes for the speakers, so they are being offered for local pickup only.
