Has anyone used Surroundtraxx by Soundtraxx?

I model in N scale and the sound decoder sounds are missing the bottom frequencies because of the small speakers. Friends of mine who have HO layouts have the same problem (speaker too small).

I think that the surroundtraxx would be a good answer as you can attach a sub woofer to it to get the base rumble and have a sound equipped decoder in the engine to handle the higher frequencies.

I haven't heard this system in operation.

Any thoughts/experiences with this approach?

OK, I'm back.  It's been a long 19 months since my most recent post, but I found that the less time I spend on forums/blog entries, the more work I can accomplish on my layout.  However, there were also a few serious events - such as being told that my job function was going to be eliminated - that made me wonder if I'd even be able to continue in mrr!  [Luckily I was able to learn other technologies, enabling me to stay with my current employer for another few years.]

I am working on design proposals for a new layout for a 'workshop' in our detached garage.  I have two basic designs to review for advice/critique.  I will present "Plan A" in this message thread.

Starting with John Armstrong's 'Givens/Druthers'.

I have old/broken links to Joe Fugate's www.siskiyou-railfan.net website that had his formulas for calculating a layouts 'operation potential'.  Does anyone have an URL/link to where these pages might be found?

Thanks.
