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.

Key Features:

  • 10-inch (254 mm) bass guitar speaker with pressed steel frame
  • 250 watts AES / 500 watts program power handling
  • 7 oz. neodymium magnet for powerful yet lightweight performance
  • 2.5-inch inside/outside wound copper voice coil with fiberglass former
  • Paper cone with cloth M-roll surround for rich lows and smooth articulation
  • High sensitivity (97.6 dB SPL) for outstanding projection

For bassists who need a speaker that delivers both power and portability, the TSB-10-250 offers a dynamic, responsive sound that can cut through any mix with ease.
