Custom designed to fit our 2.5" and 3.0" speakers.
For a better quality sound and more volume, the speaker needs to be baffled. That means that it needs to be built into the front face of an airtight box so that sound is heard only from the front of the speaker and none from the back. An un-baffled speaker may also cause vibration and rattles in your tender or trailing car, detracting from the sound.
The flat top also provides a nice insulated surface to mount your RailBoss 4 or Battery Conversion Module (Door Mount).
Outside dimensions: 2.5" baffle - 2.7" diam. X 1.6"H, 3" baffle - 3.1" diam. X 1.7"H
