Delivering exceptional punch and clarity, the TSB-10-250 is a 10-inch bass guitar speaker built for musicians who demand high output and precision. With a durable stamped-steel frame and a powerful 7 oz. neodymium magnet, this speaker offers a remarkable balance of high-end articulation and deep, controlled bass—without the added weight of conventional magnets.

Boasting 250 watts AES and 500 watts program power handling, the TSB-10-250 is designed to handle even the most demanding performances. Its 2.5-inch inside/outside copper voice coil, wound on a fiberglass former, ensures stability and consistency, while the paper cone and cloth M-roll surround enhance warmth and responsiveness.
