I have an old MB Quart 160 KX speaker that now distorts around the 60Hz (kick drum) frequency.
I'm hoping it can be fixed or else I have to replace the 160's with something cheaper like a Pioneer A Speaker since money is an issue now.
Can they be fixed and what kind of cost would I be facing if yes?

Any input will be greatly appreciated.

The damage would have to be assessed. Could be as simple as the spider coming loose, or as severe as a warped voice coil.

In short anything can be done as long as enough money changes hands...
At one time I'd did send a pair of drivers out for total rebuild incl spiders, voice coils and surrounds. I could have for less $$$ used substitutes (likely better than the originals) however warts and all I wanted to keep em factory stock...and not alter the sonic characteristics...

Edit: your in Edmonton, look up John Baker...

The first thing to go is usually the foam surrounds on the woofers. When they no longer support the cone, distortion and noise result.
These can be replaced by yourself, if you are handy, or by any competent speaker repair person. Definitely worth it.

Cheers,
Alec

Search a little on line, just rebuilt a B&W mid bass for some 620's for my brother-in-law. Patience, time and ingenuity saves a speaker every time. T

Check to see that the dust cap is not loose.

Well it appears something is wrong with my PPI amp too.
I hope it just needs a cleaning or the interconnects need replacing since they're so old they're quite stiff now.

Does John just specialize in speaker repairs?

I believe John strictly works on speakers, but as others have mentioned he is very, very good & has repaired several of mine. As far as an amp repair in the Edmonton area you could look up Alberta Radio & TV in St. Albert. This fellow (also named John) has been working on gear since the 1970's. He recently closed his storefront & is semi-retired but still does some work out of his house. He has fixed several of my vintage receivers in the past, price was always reasonable & quick turn around.
