ALLISON TWO COPPIA DI DIFFUSORI A MILANO

Pietre miliari nella storia dell'alta fedeltà, le ALLISON TWO si distinguevano dalla maggioranza dei diffusori in circolazione perchè oltre ad avere una precisione di suono con bassi corposi e ben frenati e una medioalta che ancora oggi per averla così bisogna spendere migliaia di €, grazie alla loro conformazione ricostruiscono una scena sonora molto reale. Completamente restaurata, componenti originali condizioni eccellenti. Specifications Speaker complement: Two 8" (203 mm) woofers; Two 3 1/2 " (89 mm) Convex Diaphragm mid-range units; Two 1" (25 mm) Convex Diaphragm tweeters Crossover frequencies: 350 and 3,750 Hz Crossover network: LC half-section at both crossover frequencies.
