Fitting Sound to Bachmann Windhoff MPV

[zr2498]

This is a relatively straightforward sound installation.

I wanted to try out one of the new ESU speakers in the MPV. This is a smaller version of that used by Cavalex in the Class 56.

It does mean some cutting and carving is needed to the cover on the base of the driven car.

 

This is the kit used:

 

 

The MPV driven car.

 

 

Underneath.

 

 

The speaker to be used.

 

 

Under the cover.

The speaker will just fit if resting up against the white washers as shown below. Any little protrusions from the chassis bed fixing have been clipped off.

 

 

And the lugs clipped and filed from the speaker casing.

 

 

Below is shown the removal of material from the underside cover. The speaker sits to one side, and so one edge of the cover also has to be removed to allow the fit.

 

 

The speaker is shown against the cover.

 

 

The speaker was fixed to the chassis with black tack, with the speaker wires threaded through the chassis adjacent to the motor housing. The decoder was fitted and speaker wires soldered.

Ready to test.

 

 

The MPV was connected to a Lok Programmer, and the the treble / base values adjusted. This made a huge improvement to the sound which was already excellent with the ESU speaker.

 

The future? Perhaps fitting floodlights and beacons.

I wanted to store the MPV without having to uncouple the two cars. The coupling seems to be rather fragile, and is not only easy to damage but it's easy to get the cam for the coupling misplaced so that the coupling sits too low.

So I have joined a couple of Peco SL-43s together:

 

One pair of the aluminium sections is cut into two, so that the remaining larger pieces bridge the two base plates.

 

 

To stiffen the connections at the 1/2 section aluminium section joins, styrene strips are inserted to bridge them.

I will check out your suggested changes to bass and treble and amend my source file so that others will benefit. My plan is to do this for every sound set in my range but there are only so many days in the week… 🙄

Sounds like the MPV could have particular benefit though, so I’ll do that asap.
