Tetra 506 Custom loudspeakers

Form follows function with these funky-looking yet exquisitely crafted loudspeakers, and its large ported enclosure with triangular top created a soundscape that was “very open and dynamic.” The 506’s high sensitivity made them a perfect match for many SET amplifiers, and we found that we could rock at very high listening levels even with just a couple of 300Bs at the helm.
