These are Rectify Series drop-in speaker system for Life-Like Proto 2000 E-Unit locomotives and require no frame modification or weight removal.
 
There are three different systems available:
 
E-Units with a long weight (these may be limited to E6 models)
The LLPR-ELBK-RC1 rear-mount system mounts where the factory PCB is. A recess behind the cab permits installing a LLPR-PAXF front-mount speaker. I used a Nix Trainz Decoder Buddy Mini held with one of the stock PCB screws. A TCS KA1 was installed along side the Decoder Buddy.
 
E-Units with a short weight (these may be E7/8/9 models)
The LLPR-ESBK-RC1 rear-mount system mounts in the space behind the factory PCB and spans the rear coupler. The LLPR-ESFR-RC1 front-mount system mounts in the space behind the cab and leaves room to route the wires around it. The space where the factory PCB is mounted is available for a Nix Trainz Decoder Buddy Mini or hardwired decoder installation, along with a stay-alive.
 
Life-Like's later P2K E-units were fitted with sound and are the same as the current-run Walthers Proto E-units. For these use the WLPR-E8E9-RC1 speakers.
 
The speakers come fully assembled and tested.
