Example 2: Zimo MX644D with 2x Zimo LS18X13X13-1W Dumbo speakers

Freightliner 70001 gets the DCC Sound treatment today...

MX644D 21pin sound decoder is easy enough. The narrow body means we are limited on speaker choice, so opt for a pair of Zimo Dumbo LS18X13X13-1Ws in the provided recess, which fit comfortably and connected in parallel sound really great. We attempt to include the sample 470uF/25V capacitor for stay-alive, but this proves just too big preventing the body from going back on. The loco runs well anyway, so the cap is removed.

Back together, a very simple install, and looking good exiting the tunnel!

Example 3: Zimo MS440 sound with IceCube speaker

Kit: MS440D/C with IceCube28X18X08 speaker, 17000uF SuperCap

Revisiting this model now, and making use of the latest Zimo MS440 sound decoder and one of our IceCube speakers. This is a really simple install.

Plenty of space for the IceCube speaker, and we happily found room for a SuperCap17000uF for stay-alive in the roof too.

Cab slides up on this one so we can pop a driver in the rear cab too.

Example 4: MS440, SugarCube and directional cab lights

Kit: MS440C; SugarCube35X15X10

Another take on the same model, this time with a good dual SugarCube speaker and we also take the chance to rewire the rear cab light so it is directional instead ot both cab lights on at the same time.

A few more photos of a similar model, same kit, with the sample 1000uF capacitor that comes with the MS440 also shown. This one with the IceCube28X18X08 speaker again.
