A tour de force, the Logos combines soft curves with the finest materials to create a compact, yet stunning design. The Logos is a triumph of art, engineering and imagination.

At the outset we recognized the center speaker to be the most important component in a home theater system. Our design team started with a clean sheet of paper and began the quest to create a reference standard ESL center speaker for home theater application. This would be one of our most challenging projects.

Old but still excellent
Big, heavy, but still excellent in 2014. Curved electrostatic hybrid that is working seamlessly well with fresco surrounds and apogee mains. It has that great sound staging that the apogees have and it's easy to believe that dialog is coming from behind the screen rather than below it. Works as well with music of course. There is some worry about panel failure as I don't think there is parts availabilty anymore. This is a 20 year old speaker that operates as new, which is good news for those buying new martin logan speakers today.

The best center speaker ever owned
If you can find a piece buy it. It's still the best center speaker around. Ok, it's rather big and your wife may say no, but it's worth it! Enjoy your day !
