Description
The RS125 is a 5" (13cm) bass-midrange driver from Dayton Audio. With its impressive technology, the RS125 sets new standards in the field of loudspeaker drivers. It owes much of its exceptional clarity and dynamics to a black anodized cone, heavy-duty 6-hole cast frame and gold binding posts. In addition, its low distortion characteristics and high excursion set the RS125 apart from conventional woofers. Is it time to give your sound system an upgrade? Then the RS125 could be just the thing for you.
