These are Rectify Series drop-in speaker systems for Life-Like Proto 2000 PA units. They do not require frame modification or weight removal.
 
There are two systems available:
 
The LLPR-PAXR-RC1 rear-mount system mounts in the rear recess where part of the factory PCB was. This leaves room for a Nix Trainz Decoder Buddy MINI or a hard-wired decoder installation. If choosing only one speaker, this is the preferred one.
 
The LLPR-PAXF-RC1 installs in the weight recess behind the cab and provides room on both sides for the wires to pass. This small speaker provides excellent localization of the horn/bell and a thicker overall sound. This speaker would not be ideal for use alone.
 
Dimensions are:
LLPR-PAXR-RC1: 13mmH x 32mmW x 25mmL
LLPR-PAXF-RC1: 6mmH x 15mmW x 32mmL
