sda srs 2.3 polyswitch removal

wilyJ

I have the sda 2.3 speakers, serial# - SRS 2.3 L 3955, they have always sounded muffled with no treble - am wanting to remove the polyswitches as some members have suggested. I am trying to identify them correctly - is a schematic available for the crossover or is a part number available. Pictures would be great - I'll take anything! Already modded the crossovers with new audio film capacitors - made no difference to the sound. Wanting to try this first before replacing all the tweeters.

Hello, here is the crossover schematic, the poly switch (Safetyguard) is shown. You should be able to test the switch with a volt/ohm meter to see if it is open.

Two different photos of what they can look like. You should replace them with a 10 or 12 watt 1/2 (.5) ohm resistor. If you do not your tweeters may be too bright.

I'm looking at the right channel board and I don't see any safety guard components. Looks like it should be physically located next to C5.

If one is not there I would think there should be a wire to jump the connection.

Looks like it's just above the Molex connector.
