If you are using the receiver for music, then repairing your vintage Hi-Fi receiver is the way to go. It depends if you are planning to use it to listening to music or movie’s soundtrack. Should I repair my vintage Hi-Fi receiver or purchase a new stereo / surround sound receiver? The problem should be the receiver if the new RCA cable doesn’t fix the hum noise. But if there is no hum noise after the subwoofer is turned on, then the problem could be that the receiver or the RCA cable connects the receiver and the subwoofer. If the subwoofer is making a hum noise after power on without the receiver connected to it, then we know the problem is the subwoofer. Slowly turn up the volume control on your cell phone or iPod until the subwoofer detects the signal and turns on the power. If your subwoofer doesn’t have the power on switch, then you can use a 3.5mm headphone jack to RCA cable connects a cell phone or iPod to the subwoofer input. Plug in the power cord of the subwoofer and switch the off/auto/on switch to the on position if your subwoofer has this switch. Unplug the input cable on the subwoofer input. Is there a problem with my subwoofer or receiver? The same reason applies to the mid-range or tweeter as well. Rebuilds are the only way you can get your original speaker back. The best way for speaker restoration is by rebuilding your original woofer. The original woofer matches the crossover, mid-range, and tweeter.

The original woofer installed by the name-brand manufacturers is designed and tested with many years of research and fine-turning.

Should I replace it with a newer and better woofer? Frequently Asked Questions I have a pair of vintage speakers with the woofers (bass speakers) damaged or making a buzzing noise.
