#38 Hornby Class 37 TTS Sound - Mega Bass Speaker Upgrade

The is the first in a two-part series on upgrades and improvements that can be made to a Hornby Class 37 locomotive with TSS sound.
In the second video, we'll look at adding stay-alive capabilities to help keep the running smooth and steady, but for now, we're upgrading the stock speaker to something a little better...megabass!
The steps outlined in this video are applicable to all TTS sound decoders (and many others). The only differences being that in some locomotives - not least most steam locos - the space inside can be rather limited and you may not be able to fit such a large speaker into the body.
Remember that in all cases where a Hornby TTS decoder is used, you must also use a 8 Ohm speaker (or two 4 Ohm speakers in series, adding up to 8 Ohms). This is different to LokSound V4 decoders, which can use a 4 Ohm or 8 Ohm speaker.
Speaker impedance and decoder specifications for all common sound decoders are explained in more detail in our free guide, which you can download here: tinyurl.com/dc...
