Memphis MS25 2.5" M Series Speakers With In-Line Crossovers

The Memphis MS25 is a pair of compact 2.5-inch M Series vehicle speakers designed for factory locations commonly occupied by small full-range drivers or tweeters. They provide an upgrade path for listeners who want more capable midrange and high-frequency reproduction without moving to a larger speaker location. The package includes in-line high-pass crossovers and OEM-style mounting adapters for supported applications.

Designed as the M Series “Twiddler,” the MS25 covers a stated 485 Hz to 20 kHz frequency range. This makes it appropriate for systems needing upper-midrange and treble fill from compact dashboard, sail-panel, or other factory speaker positions. Its 25-watt RMS power rating suits properly matched factory or aftermarket amplification.

A woven carbon fiber cone provides a rigid, lightweight diaphragm, while the rubber surround supports controlled movement. Together, these materials are intended to support detailed playback in the MS25’s operating range. The compact neodymium motor helps keep mounting depth limited for OEM-oriented installations.

Each speaker is fitted with a 6 dB high-pass crossover supplied in-line with the wiring. The crossover helps limit low-frequency content sent to the compact drivers, supporting their intended role in a multi-speaker car-audio system. Use the supplied crossover when installing the speakers as directed for the application.

The MS25 is supplied as a pair and includes an OEM replacement adapter intended for direct replacement in many General Motors, Toyota, and Mercedes vehicles. Memphis also identifies the model for a range of OEM locations including Ford applications, but fitment should always be confirmed for the specific vehicle. It can be used as part of a factory-speaker refresh or alongside larger M Series speakers in a custom system.

Key Features

• 2.5-Inch Compact Format: Fits small factory speaker locations where larger drivers are impractical.
• Carbon Fiber Cone: Uses a rigid, lightweight cone for midrange and high-frequency reproduction.
• Rubber Surround: Provides a durable surround material for everyday vehicle use.
• In-Line High-Pass Crossovers: Helps filter low frequencies before they reach the speakers.
• OEM Replacement Adapter: Supports direct-replacement installation in many compatible factory locations.
• Neodymium Magnet: Keeps the motor compact for limited-depth mounting positions.

Design & Installation

The MS25 combines a carbon fiber cone, rubber surround, and 25 mm neodymium magnet in a compact 2.5-inch speaker assembly. It has a stated 1.3-inch mounting depth and does not include grilles. The design is intended for applications where installation space is limited and the original vehicle location is retained.

Confirm the vehicle’s mounting pattern, available depth, factory impedance requirements, and wiring before purchase. The supplied OEM replacement adapter is intended for many General Motors, Toyota, and Mercedes applications, while vehicle-specific fitment can vary. Wire each speaker through its included in-line 6 dB high-pass crossover and match amplification to the 25-watt RMS rating.
