Carefully Designed
The B Series 4 Open Speaker is similar to our flagship 5 Open. It has one (1) single 15” (381,mm) bass driver. The solid bamboo 3-ply laminate finish, the full range driver reflects Tri-Art’s commitment to creating a superb, natural sounding loudspeaker. A design that intentionally does not sound like a conventional speaker. The 4 open with its impressive soundstage, depth, spectacular imaging and articulate accurate bass, will most certainly redefine your perception of how real music can be presented from an audio speaker.
