This speaker has the makings of a reference. It brings together and rolls into one all the virtues of compact speakers; and in fact does so in such a way that you’d have to put it in the super seller family of loudspeakers. Perhaps this is already the case. And we have not mentioned two important facts—the Berlina is a closed chamber loudspeaker and it is brand new. Most designers oddly enough regard the bass reflex design approach as an unavoidable truth. This isn’t the case, according to master designer Dr. Roland Gauder, and in fact he offers a long list of why you should avoid using a bass port. Basically, a bass reflex port in a small 6 liter enclosure can extend the speaker’s bass response by an extra octave.
