DCC Sound Speakers - DCC sound installations

We are delighted to announce that we now offer O Gauge models with DCC sound conversions using our own exclusive range of CJW speakers produced to Cliff Williams specification and are now available. The speakers produce a much higher level of bass and come in two sizes and have been well received with many regulars wanting that extra bass out of their DCC sound locos.

The speakers are used in DCC sound installations so ask Cliff if your loco is a suitable candidate for DCC sound conversion.



There are many new models being produced by Heljan, 2020 will see lots of new releases so if you are interested in owning one of these locos supplied by me with DCC sound fitted please call to discuss your requirements.


Already own a Heljan loco that you want converted to DCC sound?

Get in touch to discuss having your existing Heljan loco fitted with DCC sound.



All DCC sound locos are fully tested and calibrated for optimum running performance on a full test circuit, we do not use a rolling road or two yards of track to test the installations out! The CV settings are set as default so if you need to reset the chip then CV8 to 008 returns the settings engineered by Cliff over extensive testing..





You can hear and see some of Cliff's other work using our exclusive new speakers in this video - filmed on John Ryan's layout ( new DVD featuring John's layout coming soon!)
