View Full Version : 4333B Internal External Crossover Swich

Just got a super clean set of 4333b's and Flipped the switch to go from internal to external. Switched it back to internal and now the woofer doesn't work! :barf:Any thoughts? Can I get a new switch?

The first thing I would do is rotate the switch back and forth and give it a squirt of Caig Deoxit. They are notorious for corrosion, especially if they have been subject to a humid atmosphere.

Enjoy, they are a fun system.:)

Hope you got it working again. I've read here that the switch is a notorious weak point in those and similar crossovers. If you take it apart you'll see how substantial yet antiquated the switch is and it most likely has dirt or corrosion issues from being in one position for so long.
