Speakers listed by type. We are best known for our superb bookshelf speakers, though all our products share the same uncompromising tonal and build quality. All of our speakers are highly reviewed by users and professionals alike. Special emphasis must also be placed on our tower speakers, the Classic Four and Absolute Tower, both of which are perfect for music or home theater use. Our in-ceiling speakers, part of the Architect Series, are unique in featuring a patented 3-tweeter array that is able to produce sound across a wide field with little to no loss in audio quality.
