FAQ

Frequently asked questions

Straight answers to what people ask us most. Anything else, call (02) 9675 5511.

Can you replace a blown speaker driver?

Where a genuine or suitable replacement driver is available, yes. Tell us the brand and model and we’ll check before you bring it in.

My subwoofer hums even with nothing playing. What’s wrong?

Usually failing capacitors in the plate amplifier or a grounding issue. It’s a common and very repairable fault.

Do you repair PA speakers for venues?

Yes. See mixers and pro audio.
