No. There is not room enough for a 1.5" oval speaker. Even an oval speaker that would fit would have to be only around 9/16 of an inch wide. It would be questionable at best as to whether any more sound would be produced. The speaker mounts in the coal bunker, not the tender. The coal bunker is substantially smaller than the tender. I have an HO Shay with the sound unit and am pleased with the sound volume. It is only a matter of adjusting all the other sounds to accomodate the rather low volume exhaust chuff. This is actually extremely prototypical. The Shays had a very quiet exhaust chuff compared to most other steamers. I wouldn't make plans to modify a thing until you have heard it the way it is designed. I don't believe you will be disappointed. Those who are, are not familiar with the prototype. One more thing. I noticed one replier noted the the sensitivety to dirty track. This can be easily over come. By probing the wiring harness and finding the power wire to the decoder, a small capacitor can be placed in the power wire. This will allow power to be stored in the capacitor for just those sort of circumstances, thereby eliminating any loss of power to the decoder. It's tedious work not recommended for a novice. It will work however, and produce good results. The capacitor will however have to be installed in the cab of the loco, because of space constraints. You can make it almosr invisible though by painting it flat black. <br /> <br />[quote]QUOTE: <i>Originally posted by scubaterry</i> <br /><br />Cacole - anyway to put a larger maybe 1.5 in oval speaker in it? <br />Terry <br />[/quote]
