These are Rectify Series drop-in speaker systems for Life-Like P2K S1/S3 locomotives. The speaker requires removal of the 1.5 oz. weight and factory PCB. The speakers mount using the factory screws used to hold the weight in place.
 
Two versions are available:
 
The original LLPR-S1S3-RC1 is a long speaker that uses the screw-mounts on both the front and motor-mount positions. This speaker requires use of a small hard-wired decoder.
 
The LLPR-S13S-RC1 is a new, shorter version that uses the front screw-mount and hovers over the truck. A LokSound 58921 Direct w/PowerPack decoder can then be mounted to the motor with mounting-tape.
 
The speakers come fully assembled and tested.
