This is a Rectify Series speaker system for Broadway Limited ES44AC locomotives. This speaker requires the removal of the stock Paragon decoder and smoke-unit. A Nix Trainz Decoder Buddy, drops right in place using the stock mounts and screws and the speaker rests under the mid-hood under the exhaust stack.
 
The stock speakers are simply two, flat, round speakers wedged in the fuel tank. This leaves no room for an enclosure of any kind.
 
The speaker comes fully assembled and tested.
 
Dimensions are: 14mmH x 18mmW x 58mmL
