N Scale Kato PA/Rapido FL9 Speaker Box 3PK

This 3 pack of N Scale short speaker enclosures are designed specifically to fit the Kato N Scale ALCO PA Units (DCC READY ONLY) & the Rapido FL9 and to mount atop an 11mm x 15mm x 3.5mm speaker.  Keystone Details recommends this speaker.  The housing also sports a channel for rear LED wires and is wide enough to glue an 0406 led into the rear for backup lights if needed. 

Once the speaker is glued to the edges of the open end of the enclosure, the rear of the chassis must be milled. Some electrical tape, Kapton tape or thin styrene is required to prevent the exposed metal of the speaker housing from shorting across the milled frame.  Milling dimensions will appear here later.
