    Just picked up an A/B pair of Athearn F3 units from eBay (non-sound version). Has anyone updated these for sound? If so, any tips on speaker selection or on lighting? I had an TSU-1000 decoder for this model on the shelf, so planning to go that route for the decoder.

    Keith Robinson has very nice sugar cube type speakers that sound fantastic. He's great at installing decoders, lighting and speakers. He did an excellent job on an SD40-2 for me. I'm sure he'll chime in and help you out with advice.

    Bob, that is an easy installation with the TSU-1000 but far easier with the TSU-GN1000 I have a speaker enclosure that I designed that fits above the rear truck with a 20mm high bass speaker inside. Contact me via PM for more advice.

    Just trying the robot thing, I have a couple of the speakers Kieth made and I highly recomend them.

    Thanks Keith,

    I will take you up on your offer (and send a PM). I have one TSU-GN1000 already, and would very much like to see your speaker design in detail. How about lighting approach?

    Many Thanks to All.

    Keith provided the speakers and enclosures (a perfect solution), I grabbed a couple of TSU-GN1000 decoders and these are running great on the Crawford and Cherokee.

    Bob, good to hear you got them installed and running. What do you think about the sound quality?

    The sound quality is quite good. When I built the enclosure that you sent, I was careful to close up all of the seams with the polystyrene epoxy. I have been tweaking sound settings in Decoder Pro/JMRI and am most happy with custom settings using the equalizer. In particular, I have been trying to get the two units to sound just a bit different such that it is clear there are two different engines there.

    The speaker/enclosure gives good lower end response and plenty of volume. Maybe I can post a video once I have settled on a final configuration.
