TTS Speaker

[Antan1]

Hi, I'm currently swapping out the Hm7000 stock speaker for a Rail Exclusive big boomer. Are the 2 wires plus and negative as i need to solder on the stock decoder speaker plug.
Thanks Anthony

You can connect the speaker wires any way round. Pos & neg are only significant when using 2 or more speakers

The standard HM7000 speaker is not TTS. HM7000 uses a standard sugar cube speaker while the TTS speakers are usually 28mm round speakers.

Thanks for the replies, yes the stock speaker is being replaced.

Regardless of whether TTS or HM7K the replacement has to be 8 Ω impedence.

Yes it's 8 ohm, I'm interested to see if it will be noticeably better than my other class 31 with the standard hm7000 speaker.

TTS is a relatively low fidelity sound compared to TXS sound using like for like speakers. TTS can be improved with a better speaker as can TXS.
