Where can i find cct diagrams for my Wharfedale SW150 subwoofer? Power light goes on, all connections are fine but internally i can hear it doesn't switch on.

Some basic trouble shooting is required here. First you need to see if it is a problem from your source or the sub. Try a different source to the sub-woofer and see if it changes the response. If still nothing on the sub, then most likely there is an issue with the amp or driver. Check to see if there is a fuse on the sub, if so, it could be blown. There could also be an issue with the auto switching circuit on the subs amp, in that case, it would need to be repaired in the shop. But before that I would check all of the connections to the sub, and also to the driver in the cabinet. If everything looks good, then put some type of source directly to the woofer to see if it works, if you get sound, then looks like the amp has a problem. Again a repair or replace issue.

Hiya, try a different input cable (from amp to sub) if you have make sure that is ok.

Failing that if there is an earth in the plug, try to disconnect that (earth loop) - unlikely but hey electronics.... anything possible :)

If still there with new cable, earth off etc, then the Yamaha could have a problem but find that difficult to swallow...

Let me know if helps, see any other possibilty
Best of luck

What 'floorstanders'?

Its internal amp is for its own subwoofer ONLY, but if you use your own amp's full-range speaker-level outputs to feed two chanels entering the sub you can tag the 'floorstanders' onto the sub's speaker terminals as speaker wire extenders. Your amp will be powering the floor units.

I'd keep the sub separate and feed it LFE only if it was mine.
