Introduction to the Martin Logan Theos Electrostatic Speakers

For many years now I've had a love for Martin Logan's speakers. Though they have always been beyond what I was able to afford for myself, I'd often make a trek over to the dealer to have a listen when a new model was released, or I had a recording I really wanted to hear. The speed and transparency that their electrostatic panel seemed to offer compared to a conventional box speaker was always enchanting, and unlike many other speakers of similar designs, they played well without a massive amplifier and with rock and roll music.

At the CEDIA Expo in 2010, Martin Logan was giving one of the first demonstrations of their new Theos electrostatic speakers (ESLs) for the press and dealers. Though the conditions at shows are often less than optimal, when seated in the sweet spot of the room, the experience was nothing short of amazing. Sounds came from all around, causing me to check and make sure that there were no surround speakers setup in addition to the Theos. The soundstage up front was huge and open, and the speakers themselves were amazingly detailed. After I wrote about the experience, Martin Logan asked if I'd like to be one of the first to review a pair when they started to ship them, and without hesitation I said yes. So, here is the review of the Martin Logan Theos, which is a hybrid ESL, meaning it has an electrostatic panel with a conventional cone woofer.
