HL 3.4
The question is someway obvious. If so small speakers like HL 1.2 and HL 2.2 are able to give a so wide and rich bass response, what would it happen using a couple of larger drivers? The answer is in this HL 3.4, where the Helmholine system, made by both wooden cabinet and metal base, shows all its power in managing high volume levels and in keeping the detailed bass texture which transmission lines are properly renowned for. The elliptically shaped cabinet is made in a special high density and well damped sandwich that allows the system to be really neutral to vibrations. All ceramic drivers, a sophisticate crossover and a metal chambered base are further, important details. But ears don’t mind technical solutions, they just enjoy music.
