Martin Logan Focus ESL C18 On-Wall/Off-Wall Center Channel Speaker – Each


The painters of the Dutch Golden Age produced photo-realistic masterpieces 300 years before cameras were invented. They focused your attention using a bright, otherworldly light. Even in their most intimate portraits, the riveting light draws your eye.

This kind of sensory focus is the key to realism in your home theater, as well. It’s the job of your center channel loudspeaker to anchor action and dialogue to your screen. It must reproduce detailed high frequency information to reinforce imaging, and also blend seamlessly with the other speakers in your surround-sound system to envelope you in a realistic soundstage.

MartinLogan presents a new Masterpiece of home theater realism: the Focus ESL C18 Center Channel Loudspeaker, an electrostatic center channel speaker designed for wall-mounted flexibility.
