ESU Loksound installs in Atlas GP-7/9's

Karl I have a chop nose so I'll check it out later this week!

Thanks, I figure clearing the cab won’t be much trouble. It’s clearing the cab glass where things get sticky. You can create more room my using micro glaze on the front windows and adding a piece of electrical tape behind it to keep light from creeping through.

Here's a LokSound Select Direct #73100 in an Atlas GP-9. Pretty easy actually. Just need to mill out a bit of the frame near the back end for the speaker. There isn't much room there so custom build an offset speaker box with styrene and you're good to go. No more sanding away inside the shell to shoehorn in the Select Micro.

Hi @skytop35 , can you provide the dimensions of the speaker enclosure and the speaker size/brand you used?  I would like to add this box to my Keystone Customs repertoire.

The speaker is 8 x 12mm but I don't remember what brand I used. The enclosure I built is 9 x 16 x 4mm.

@skytop35 Thanks for the dimensions!

Since you were able to get a 9 x 16 enclosure in is there a reason you didn't use a 9 x 16 speaker? 

I put 9 x 16 speakers & Enclosures in the '95-96' Atlas GP 7/9's  and up to now like the larger speakers better but did get some of the 8 x 12's in that were mentioned here recently (haven't tried them yet).

If anyone is working on the '95'/96's I have print files up for a....

I have added ESU LokSound to an OLD Atlas GP7 Northern Pacific 565, and an old Atlas RS 5200.  Both required a lot of machining and fitting, but they both can pull more than 7 cars up a 2.5% grade.

Loss of enclosure volume. It’s not just about having a box, the volume inside adds to the sound.

Here is the 9 x 16 speaker/enclosure for a comparison (in the older Atlas models)...

I'm hard of hearing so not a great judge of sound but I'm happy with it.  Here are two of them running together at the same time although on the layout they will be running in consists with different identical coal trains, one loaded, one empty.
