Dayton Audio DS90-8 3" Designer Series Extended-Range Speaker

The Dayton Audio DS90-8 3" Designer Series Extended-Range Speaker is a compact yet powerful driver that delivers impressively clear, full-range audio for a wide variety of applications. Ideal for use in bespoke bookshelf speakers, desktop monitors, portable Bluetooth enclosures, or as a dedicated midrange driver in multi-way systems, this versatile unit excels where space is at a premium but sound quality cannot be compromised. Its extended frequency response makes it particularly well-suited for near-field listening and high-fidelity installations.

Engineered with a treated paper cone and a copper voice coil, the DS90-8 produces a natural, warm midrange and smooth, detailed treble. The total Q factor (Qts) of 0.43 indicates excellent balance for use in small sealed or ported enclosures, while the 2.5mm Xmax and 7.8cc displacement volume (Vd) allow for surprising low-end extension from such a compact frame. With a sensitivity of 84.1 dB and a nominal impedance of 8 ohms, this driver is easy to drive with modest amplification. The 70mm cutout diameter and four mounting holes ensure straightforward installation, and the 44.6mm depth fits neatly into shallow cabinets. Whether you are designing a custom audio project or upgrading an existing system, the DS90-8 offers exceptional performance in a small package.
