I'm finally working on fitting DCC and sound to my Fred Phipps 1/32 D6319.
I have nearly finished making a sealed "box" in the centre of the body under which will be fixed two 40mm speakers mounted on a stout piece of plastikard, which effectively forms a downward facing "lid" on the box.
I may cut out the chassis frame beneath these speakers to allow the sound to "escape" but have been informed this may not be neccessary.
I have the big loksound 3.5A chip blown with the relevant DB MAN engined loco plus English noises, horn etc, and have a pair of the ESU 40mm speakers.
Question, I presume I cut a pair ofholes in my "lid" to correspond with the actual speakers diameter and fix the whole speaker in its housing as supplied to the lid?
This doesn't seem right to me as you then have a small chamber behind the speaker "cone" (which is very flat) which is itself inside my "boom box", but if I take the speakers out of their housings they'll be impossible to fix and the small black housings dont look as if they are designed to be carved to provide a mounting but with their backs "cut out".
I will also have to run wires along to connect (they are going in series) which will slip through small slots let into the black speaker housings. Should I then seal the remaining slots?
Hopefully this question makes sense to someone (Steph!) - apologies for rambling on incomprehensively to everyone else. A picture would be worth several words but I can't find the camera.
I'm off to finish off sealing the "boom box", one small grille and the windows in a pair of engine room doors and I 'm done.
Next job after that is to mount the chip on the chassis and route the wiring, then its contemplating "showtime" .
