Hi Guys We have used a couple of different brands of speakers in GPs, F units, SD 60s, AM Northerns and the 2-10-0 that Jim K mentioned. Here's some links.
http://www.mouser.com/catalog/630/1505.pdf These are made by Kobitone and 4 of the 6 listed at the top of the page have plastic frames so you can fab a styrene enclosure with Testors plastic cement or MEK. They're rated at 1 watt and put out more sound then you'll need. We've also used these made by Projects Unlimited at the bottom of the page. http://dkc3.digikey.com/PDF/T072/P1897.pdf These also have plastic frames and fabbing an enclosure is easy. They even come in 4 ohm so you can use 2 in series - we tried that in an E unit to simulate 2 prime movers. These are the same brand rectangular speakers you can buy from TTX or Soundtraxx for 2 or 3 times the price. Incidentally, the 20 mm wide speakers fit into narrow hood units and we have one in an AM GP9. It fits just fine over the towers as long as you don't make the enclosure too tall - 3/8" tall IIRC. And it has plenty of volume. Try a 28 mm x 40 mm in a SHS F unit and you'll never use the stock speaker again. The PBL round speaker comes with an enclosure and is a bargain for around $15. Don't know what the wattage rating is but it sounds loud enough for me. They also make a couple larger ones but we don't know what boilers they'll fit into. But we'll find out eventually!
