John Roland Eberly III
Portable Bluetooth vintage train case conversion incorporating finished interior and storage space
Vintage aesthetic with clean sound and long battery life, more useful than just a “suitcase boombox” by including functional, decorated interior carry space
(2) 3″ fullrange Faitalpro, (1) 5-1/4″ Dayton Audio woofer
Re-purposed Samsonite mid-century train case, 13″ x 8″ x 9″. Drivers selected using Parts Express published volume ranges.
Active using 2.1 class D amplifier.
Tips & Tricks:
One problem was that the case handle rattled and buzzed, sounding like driver distortion. Adding felt pads between the handle and case solved this.
Successful project, aesthetics and sound exceed expectations. This case delivers clean sound with not distortion at full volume.
