DCC Sound Speaker Upgrade - getting great quality sound without breaking the bank!

With the ever-increasing cost of everything these days, for many, the idea of DCC sound is too expensive to consider, as a decent sound decoder will set you back £120+. However, by using a far cheaper Hornby TTS decoder and a speaker upgrade, a good DCC sound experience can be achieved at half the price! This video demonstrates upgrading the speaker on a Hornby TTS decoder using a "Volcano" speaker from Horns & Whistles Workshop.

If only Hornby made enough TTS soundchips to meet demand, but sadly they never do and consistently fall short in most things they do.

Yet another excellent demo, thank you.

Thanks Ron. Glad you enjoyed.

Nice video! I have some very expensive sound set ups but I also use a number of TTS decoders which I rate as good value for money. The only downside I have found is the lack of ability to synchronise the chuff rate on my steam locos. The speaker you have used is very impressive. TSS decoder amplifiers are rated to use 8ohm speakers, is the one you have used an 8ohm speaker?

Thanks for the video. I use TTS sound decoders for the very reason you say, affordability. I haven’t found a way to vary the volume of the sound which on a couple of my steam locos is way to loud. I can’t see a CV setting for volume. Do you know of one?

Hi Peter. You’d need to check the manual for the specific decoder as I have seen a couple of variations. The TTS manuals are all available to download from Hornby. However on this and some other TTS diesel decoders I have, CV182 controls the master volume with a range of values 1-8. There are also other CVs to adjust the volume of individual sounds listed in the manuals.
