Whistle volume is listed as CV129
My mistake 129 is the CV I experimented with.
I'ts unfortunate they didn't get all the values the same.
I bought a Digitraxx SFX064D today and have to say the whistle is nice and loud but not of the same quality as the Tsunami, saying that, it will be installed in a 2-10-0 and I think I'll be happy with that

Most of quieter whistles have more natural low frequency content. Throttle Up!/Soundtraxx has expressed their philosophy in the past on this issue - amplifier preservation, speaker protection and prevention of distortion. For example, many people use the 0.1W round speakers with Tsunami decoders; they are not well suited for low frequencies (below 350Hz); using these speakers with a Tsunami, which was designed with greater frequency bandwidth response, could damage the speakers, which in turn could DAMAGE the amplifier. Also you must consider the effect of actual impedance on the amplifier; the 8 ohm rating of a speaker is typically based on the output at 1KHz; impedance drops as the frequency drops on an inductive device (speakers are inductive) low whistles could drop the impedance as low as 1 ohm!
Using the largest speaker or speakers (two 8 ohm speakers in series works well with a Tsunami) and adjusting the built-in equalizer will improve the sound of the low frequency whistles. BTW, adjusting the EQ will help to improve the output of various speaker sizes and types.
For larger tenders, try the Intervox S11X16VNS 28mm x 40mm oval speaker or the Kobitone equivalent:
