2.5-Inch Straight-Cone Midrange Speaker – 4 Ohm, 25W RMS, Precision-Machined Aluminum Enclosure

This 2.5-inch midrange speaker features a straight-cone design and a precision-machined aluminum enclosure. With a voice coil impedance of 4 ohms, it is rated for 25W RMS power handling and 50W maximum power handling, providing a compact driver option for compatible speaker systems.

The specified frequency response is 300Hz–20kHz, with a sensitivity of 89dB. Designed as a midrange speaker, this unit can be considered for the midrange section of a multi-way audio system, with its operating band determined by the system’s acoustic design and crossover settings.

Its 2.5-inch format and aluminum housing offer defined construction features for custom speaker assembly and DIY audio projects. When used as a replacement midrange driver, both the electrical specifications and mounting dimensions should match the requirements of the existing system.
