When Polk decided to upgrade one of its best-selling models, it went all-out: It’s not really an upgrade, but more like a whole new design! The new Signature Elite S60, which replaces the outgoing S60, has new bass/midrange drivers, a new crossover, re-vamped internal bracing and a whole new exterior. In fact the only components it has kept in common with the older model are that unusual 25mm terylene dome tweeter, a cascading tapered crossover design and the fact that the cabinet is — despite its newly remodelled exterior — still a bass-reflex floor-standing one.

The Polk Signature Elite ES60 has the deepest and most extended bass of any of the models in the Polk Signature Elite range. It’s also the tallest and loudest model in the range. The other models are also floor-standers, but the Signature Elite ES50 has only two bass/midrange drivers, and they’re both smaller than the three in the ES60. As for the Signature Elite ES55, that has the same-sized bass/midrange drivers as the ES60, but again, has only two of them.
What all three models share is the same 25mm terylene dome tweeter, and what Polk refers to as its ‘Power Port’ bass reflex design. This last is actually just a down-firing bass reflex port that fires into a diffuser that ensures the very lowest frequencies are distributed
