James Loudspeaker is an American speaker maker focused on custom designs built to match a client's dimensions and decor. Its Small Aperture Series delivers sound through openings only three to four inches across, and Centergy Technology spreads three channels across two speakers, so a room needs no separate center channel. Its CUBE bookshelf speakers use aluminum enclosures, and the larger model adds a beryllium dome tweeter. Custom models include a walnut three-way speaker with a Quad Array of four tweeters and an on-wall speaker built for outdoor use.
