Adrenaline M75 Loudspeaker
The Adrenaline Series began here. This iconic model was the first to utilize the combination of Wisdom’s line source technology, innovative underhung low frequency regenerator (LFR) and exclusive Active Brain electronic crossover design. Its wide horizontal dispersion, prodigious power handling, six-foot, thin-film planar-magnetic line source provides unmatched clarity, speed, detail, dynamics and imaging. Combined with the awesome low frequency detail, timbre and power handling of the dual 12-inch, underhung, 3-inch voice coil low frequency regenerators, the M-75 provides a combination of realism and fidelity that established a benchmark for Wisdom Audio.
