The C40
The C40 is generous in both volume and drive units. Bass is plentiful and extended, and the design has been balanced to operate clear of boundaries on open stands.
The two new 200mm bass/midrange units use polypropylene cones. The lower driver is only used at the lowest frequencies, augmenting and extending bass output, substantially improving power handling capacity, and assisting bass damping.
The C40 is very reasonably priced for such a precisely engineered loudspeaker, considering the size of the cabinet. It goes exceedingly loud, handles plenty of power besides, and has generous bass delivery, so it will be particularly appealing to the cost-conscious rock listener.
