when I remove the old tweeter what goes away with it? I see 2 parallel resistor that appearts to be the candidade I think the coil has to do with the 10 inch woofer- TIA

The current model one π, two π and two π tower have a 10uF series capacitor and a 16 ohm resistor in parallel, right across the tweeter. The DX25 upgrade kit comes with a tweeter, a 10uF capacitor, a 16 ohm resistor and a pair of 0.110" spade lugs. Replace the existing 0.205" spade lugs with the new ones in the kit, and solder the 16 ohm resistor into the spade lugs along with the wires. Cut the silver colored wire on the tweeter line and splice in the 10uF capacitor. There should be no other components on the tweeter circuit. Leave the woofer line as it is.
I noticed that on one side of my speaker there is a parallel pair of resistors (looks to be red-red-black-gold). This is the parallel resitors mentioned in above post.This resistors pair is wired from the woofer +ve to the negative. Is this correct? I am missing these resistors on the other speaker. which is correct?
Basically I do not have a schematic of pi2 crossover with me and noticed the difference while changing to the new Vifa tweeter TIA

There were never any one π, two π or two π tower kits or completed loudspeakers shipped with resistors installed internally on the woofer line.
Some people put 20 ohm resistors across speakers with piezos, so maybe someone decided to install yours internally. If so, remove them.
Current models use a 0.5mH series coil in the woofer circuit, but older models don't have one. You can identify the driver by the label; Silver labels are the new ones. Models with silver label drivers have the coil, older ones don't.
