Memphis MSA1V 1" Aluminum Dome Tweeters

The Memphis MSA1V is a pair of 1-inch aluminum dome tweeters designed to add dedicated high-frequency output to a car audio system. They are suited to listeners replacing worn factory tweeters or building a component-style speaker arrangement. The compact design helps place treble reproduction where it can improve front-stage focus.

Each MSA1V uses an aluminum dome diaphragm intended for clear, detailed high-frequency reproduction. With an 88 dB sensitivity rating and a published 75-watt RMS, 150-watt peak power rating, these tweeters are designed for systems with appropriately matched amplification. They can be used as part of a balanced upgrade when paired with compatible midrange or midbass speakers.

Installation flexibility is a central feature of the MSA1V package. The tweeters support angle, flush, and surface-mount configurations, allowing installers to select a placement that suits the vehicle and desired listening position. This makes them practical for doors, sail panels, dash locations, or custom panels where space and aiming requirements vary.

Two-way passive crossovers are included to support proper frequency division in a compatible component system. Using the supplied crossovers helps route the appropriate signal range to the tweeters rather than sending them a full-range signal. This simplifies integration with compatible speaker wiring and amplification.

The MSA1V has a shallow published mounting depth of 0.6875 inch, helping it fit locations with limited rear clearance. A 54 mm, or 2.125-inch, mounting-hole template is published for this model. Grilles are included, and the tweeters are sold as a pair for a matched left and right installation.

Design & Installation

The MSA1V uses a 1-inch aluminum dome tweeter design with a published 13-ounce magnet size. Its compact form supports multiple mounting styles without changing the tweeter model. The pair includes grilles and is specified with a 2-year warranty.

Choose flush, surface, or angle mounting based on available panel depth and the desired tweeter direction. Confirm the published 0.6875-inch mounting depth and 2.125-inch mounting-hole template before modifying a panel. Connect the tweeters through the included two-way passive crossovers in a compatible system and match power to the published rating.
