Dayton Audio Reference RS125T-8

Discover the Dayton Audio RS125T-8, a 5" (13 cm) bass-midrange driver that sets new standards with its advanced features and high performance. With a shortened frame for easier mounting, this model combines an advanced motor design and rigid aluminum cone to outperform speakers that cost many times more. Equipped with a powerful motor and suspension for strong bass performance, the RS125T-8 offers exceptional clarity, detail and dynamics. A key factor that sets it apart from other models is its low distortion, which is achieved through the use of a copper ring in the magnetic gap. Manufactured in the USA, this bass-midrange driver stands for the highest quality and reliability.
