The creation of the The B Series Open Speakers is the result of 40 years of experience in the Audio industry from its designer Steve Ginsberg. The definitive shape of the speakers and the solid bamboo laminate design reflect his commitment to making reference loudspeakers, both stunning in its musicality and appearance.
“… these speakers are really amazing sounding, with soundstage and imaging that trumped many much more expensive rooms at the show.”
Spencer Holbert – The Absolte Sound (2014)
B-series 5 Open speakers
Two 15″ woofers provide impressive bass response without the boom of conventional box speakers. The midrange is sweet, voices come through with a natural real tone. Instruments are presented with space and air, with outstanding soundstage and imaging. The speaker is equipped with an external crossovers and volume control for the full range driver. The 5.0’s will work with high current tube- or solid state amplifiers, however the speakers were designed and voiced with our B-Series Passive- and Power Amplifier.
“Even while sitting almost directly in front of one Tri-Art 5 Open loudspeaker, I heard exceptional depth-of-field, not to mention great touch, impact and openness.”
Art Dudley – Sterophile (2015)
