I'm considering replacing the decoder and sound module in my Heisler for a sound decoder that's more power-efficient.
But I want to know if I can re-use the stock speaker before I begin.
I'm thinking of using a Soundtraxx Tsu-1100 Steam-2 decoder, which can drive a 1-Watt 8-Ohm speaker.
Edit: Found it, the speaker is rated for 1-watt, 8 Ohms.
