Whether it's stereo listening or the rigors of home theatre you're after, the Harmonix will deliver in exemplary fashion. The full length grille 'hides' a four driver 3-way design, comprising two 165mm bass drivers, a single 130mm midrange and a 28mm tweeter. Harmonix project a deep, tight bass response via their extended bass shelf alignment, a dynamic and non-fatiguing vocal mid-band with lucid, detailed highs. Harmonix - experience eloquence.
