I am researching info prior to ordering several Massoth decoders. Massoth recommend the 57mm 3 watt speaker for the Frank 'S' installation. I have two locomotives to chip with both being decoder interface (one is analogue and the other factory fitted type 1 LGB decoders).
This morning I dismantled the analogue locomotive and for the life of me cannot see where a 57mm large magnet (3 watt) speaker could fit (Massoth recommended speaker for this locomotive). I am considering the 50mm speaker (#8241060) as I feel it could be fitted with the rear section of the speaker (magnet end) sealed into the boiler extension behind the smokebox. This way the boiler moulding/smokebox would act as an enclosure and the diaphragm would face the interior of the loco body. There seem to be enough 'holes' to allow sound to escape. I had thought of a tender installation but a similar problem exists - where would the 3 watt speaker fit? The thinner 2 watt speaker may fit under the coal load, but then holes would need to be drilled in the coal moulding for sound to escape. This would then impact visually on the coal load moulding.
Any thoughts based on experience? Also, is it possible to fit an 'L' and an 'XLS' in the same locomotive? At present the 'XLS' is on special and an 'LS' plus speaker will cost more. I am thinking that for a powered tender locomotive maybe the driving characteristics would be different. Would it be better to stick with a 'LS' in the locomotive and an 'L' in the tender. I am thinking that they would have similar motor driving values (accel/decel/spped curves).
