[quote user="Renegade1c"] the reason that the volume on your tsunami ma not be very loud could be lack of a baffle. The one I know I had a problem with (not with my tsunami but my other soundtraxx loco) was that I had a small speaker (3/4") with no baffle (no echo chamber). This was for a shay. it made the sound so weak I could barely hear it at all. I had to go back in and seal the tender part so that no air could move in and out of the coal tender in order to have a baffle. It was much louder after that. Also for the chuff rate have you considered using a cam on the axle? The Tsunami includes a feature for this. This is what i use to control the chuff rate on my loco allowing the chuff to match perfectly with the cylinders.[/quote]The tender shell is sealed up and is the baffle/enclosure for the speaker.  I did my initial testing with a soundtrax speaker in a soundtrax enclosure.  I just got the high boiler 4-6-0 and put an oval speaker in it with the same volume level as the low boiler version.  The volume level is acceptable; however it is not as loud as my MRC and QSI equipped engines.  I have the Tsunami turned up to max on the whistle and turned way down on the MRC (set at 0 of 0-4) and QSI (set at 45/127) units.  Except for the whistle, all sound levels are run at 1/2 to 3/4 volume on the Tsunami.I did not want to mess with a cam for chuff rate.  I just expected a wider chuff rate to be available in the Tsunami.  At max rate it just hits 4 chuffs per wheel rev with the large driver version of the Bachmann 4-6-0.  Above crawl speed; you can not tell that the chuff rate is slightly low (for all that I know, it is dead on at higher speeds).I will put more information in my next project update as I just got the high boiler version of the 4-6-0 this week.
