Hello.

Please help me to identify T33 (SP1210, 4 ohm) polarity.
It has brown and blue wires coming out, and no sign of "+/-" marking near terminals.

Thank you very much.

Blue is positive for all KEF tweeters. If in doubt, connect a high current 1.5V cell/battery and observe the motion of the diaphragm. Motion away from the magnet when the cell positive is connected to the blue and the negative to the brown is correct.
