DCC Impulses Column - 2
Steam loco and tender - in reality tenders don't make much
noise, but they are one of the best places to put speakers in
models.
Multiple diesel units with a single sound decoder - "MU
hoses" can carry audio between units to distribute the
sound across a lash-up.
Starting out, let me say that I'm going to deal with multiple
identical speakers in this column. I've tried larger (woofer) and
smaller (tweeter) speakers with crossover networks in mod-
els. Even in G scale, where I could use a 4” in the tender and
a 1-1/2" in the smoke box, I found the results were less than
what I wanted and certainly not worth the effort or expense.
In that case, the 4" provided a depth of sound that was only
diminished by trying to add a "tweeter."
Decoder specifications
Your decoder was designed to provide a certain amount of
audio power into a specific load impedance. A very common
1: N-scale Kato baggage car with (an older) DSX sound-
only decoder and two speakers to improve bass response.
