The B Series 4 Open Speaker’s 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.
The appealing sound of the 8” (203.2mm) full range paper cone cloth edge driver eliminates the midrange crossover and its phase inaccuracies. Phase is instrumental in the listening experience. The human ear is quite sensitive to phase, which the ear uses to locate sound, and it is particularly sensitive in the mid-range frequency. The single driver eliminates phase anomalies associated with crossover designs. The result is a far more detailed and accurate presentation free of crossover artifacts. The full range driver features lighter cone material making them quite efficient. They sound magnificent with SET amps, tube amps or high-power amplifiers.
Bamboo is used throughout the Tri-Art Audio Line for good reason. Steve Ginsberg calls it, “Mother Nature’s Carbon Fiber”. Bamboo is inherently and the choice of many musical instruments today. Moreover, bamboo grows at an exceptional rate replenishing every five years compared to traditional hardwoods 25-30 years. Tri-Art selected 3 ply bamboo to construct many of the structural elements of their systems rather than the industry standard of metal or plastic. In addition to its natural aesthetics, 3 ply solid bamboo laminate was chosen for its performance properties.
