Steve Viney Posted June 7, 2020 Share Posted June 7, 2020 Hi I have just bought a Heljan '0' gauge Mogul which I am very pleased with. I run DCC and bought a Loksound 5L as I knew it would be a straightforward job to plug it in and connect a speaker. The speaker is 'Rail Exclusive' SP 40X20X7 big BOOMER which I had left over from a previous project. It is an 8 Ohm 1 watt model. I have used them before in other locos but with a Zimo decoder and they work well. Unfortunately the sound is VERY distorted even when I turn down the volume. I'm not sure what the problem is but assume that the speaker can't handle the output from the decoder. I'm not really familiar with ESU decoders. I don't really want to change the decoder. Is there anyone who can advise me? If I do need a different speaker which should I use? Thanks for your help. Steve Link to post Share on other sites More sharing options...
Steve Viney Posted June 7, 2020 Author Share Posted June 7, 2020 I've just tried connecting the decoder to a Tannoy hi-fi speaker and it still distorts so it must be the sound file! Steve Link to post Share on other sites More sharing options...

Steve Has the speaker been sealed correctly, as this new range of speakers are not always airtight or sealed. Charlie Link to post Share on other sites More sharing options...
Steve Viney Posted June 7, 2020 Author Share Posted June 7, 2020 I agree Richard, but I would have thought that it would not distort but be a feeble sound. Perhaps it's simply that the sound file was recorded badly. I'll contact the suppliers tomorrow and see what they say. Steve Link to post Share on other sites More sharing options...
RMweb Gold Roy Langridge Posted June 17, 2020 RMweb Gold Share Posted June 17, 2020 How are sounds like horns? One of my most disappointing sound conversions is a Class 17 with the Chinnor sounds. The horns etc. are fine, but the engine sounds are distorted. I have tried different speakers but have concluded that the issue is with the recording, not the speaker.

A good speaker will give plenty of sound at a low input. 3W should be more than enough and is likely to be more efficient than these tiddly dcc sound speakers. 2 Link to post Share on other sites More sharing options...
