Eliminate floor and ceiling reflection
The Line Source design eliminates floor and ceiling reflection while distributing sound levels uniformly across the width of any room.

Big bass in small boxes
Featuring Sage Series dynamic woofers that are more than twice as powerful as typical woofers for great bass without huge, ugly boxes that are difficult to place.

Power over Distance
Line Source provides a much better power constituency than point source. This is great benefit when designing entertain net space in large modern open floor living space as well as multi tiers theaters.
