Michael, The new QSI titan provides stereo sound and you actually direct, by percentage, what sound come out what speaker. I assume you are using a Tsumani and even with 2 speakers all sounds are sent to both speakers. Ed Sauers

I can put a much larger speaker in the tender (better bass). Bass sounds are less directional than high frequencies. I thought: What if I put a smaller speaker in the smoke box and a larger speaker in the tender? Will it seem like the sounds are coming from the engine? The results: Nope. After I squished everything into the boiler and put it all together, I thought there was no sound at all coming from the locomotive - I assumed I had broken a wire or something catastrophic. Wrong. I took the boiler off the chassis, and if I put my ear right next to the speaker that normally lives in the boiler, I could hear it doing its thing. The larger speaker in the tender was so much more powerful that it sounds just as if there is only one speaker. BTW - the speakers are the same impedance. I had them hooked up in parallel. Maybe (1) if in series they would be better matched (not likely), or (2) I could attenuate the tender speaker. Not this round, I need to get the locomotive back in service. The good news is now I can put a much larger stay-alive capacitor on the Zimo decoder in the locomotive, and I only need two wires between locomotive and tender. -Michael Eldridge [Non-text portions of this message have been removed] ------------------------------------ Yahoo!
