No battery test. Besides my eyesight is horrible. I guess I'll keep investigating. If I could figure out schematic...I'm sure my answer is pretty simple..just not to me. I was hoping other DQ20 owners could look at theirs.
What is the model number on the tweeter? Is it a new one? If you are talking about the wires coming from the crossover those have meaning but those have to matched to correct terminals on the tweeters.?
If you can not find any polarity marks of any kind on the tweeter and lacking any test equipment you are left with a battery test. It will work but you have to be very careful so that you don’t burn out your tweeter.
The key is to be ready to observe very small dome motions so you need strong light and keen vision.
What you are looking for is the connection that causes the dome to move forward(away from the magnet) this connect has the + terminal of the battery attached to the + terminal of the tweeter.
the connect MUST BE VERY SHORT, the shorter the better and certainly less than 1/2 second!
If you agree to take full responsibility to proceed is
:
To test a tweeter for polarity, connect one of its wires to the positive terminal of a battery and the other wire to the negative terminal; if the tweeter cone moves outwards when connected, the polarity is correct; if it moves inwards, you need to swap the wires to achieve the correct polarity.?
Key points to remember:
- Use a battery: A standard 9-volt battery is usually sufficient for testing polarity.?
- Observe the movement: When you connect the wires to the battery, watch if the tweeter cone moves outwards (correct polarity) or inwards (incorrect polarity).?
- Swap wires if needed: If the cone moves inwards, simply switch the wires connected to the battery terminals to correct the polarity.?
Why is polarity important?
- Sound quality: Incorrect polarity can lead to sound cancellation between speakers, resulting in a poor audio experience.
- Phase alignment: When multiple speakers are connected, ensuring correct polarity helps maintain proper phase alignment for a cohesive soundstage.?

To test a tweeter's polarity using a 9-volt battery, touch one exposed wire of the tweeter to the positive terminal (smaller end) of the battery and the other wire to the negative terminal (larger end); if the tweeter cone moves outwards, the wire connected to the positive terminal is the correct positive lead, and if it moves inwards, the polarity is reversed.?
-
Positive and negative terminals:
The smaller, circular terminal on a 9-volt battery is the positive, and the larger, flat terminal is the negative.?
-
Cone movement:
If the tweeter cone moves outwards when touching the positive terminal, the polarity is correct. If it moves inwards, the wires need to be reversed.?
-
Brief contact:
Only touch the battery terminals to the tweeter wires for a very short time to avoid potential damage.?
