Assembling new RD0194-1 SL 2000

bennifabio

Hello,
just assembled new RD0194-1 SL 2000 on my Polk Audio 10 series.
Unlike the previous ones ( old SL 2000 ) there's no " + " symbol on the inner part of the Items.
I just connected them randomly, I think the sound it's ok, but I'd like to know if there's any possibility to have a different phase.
Thank you so much !

The + (positive) terminal should have been red, or had a red dot next to it. Can't recall, it's been a while since I put mine it.

Hello WilliamM2,

thank you for your reply. And what about the color of the cables for ex: white is the positive one?

Thank you again.

on Polk's BLACK is ALWAYS the positive wire

Thank you pitdogg2,
so red pin should be connected with black cable.

bennifabio

The same thing for L and R channels, correct ?
Thank you once again !

WilliamM2

Same on both.

Polk can be inconsistent with the wiring color on older speakers. Mine didn't have a black wire to the tweeters, so I just made a note of which color wire was connected to the + terminal before disconnecting the old tweeters. Just in case you remove any other drivers.

... I wasn't so wise... Is there a method to find a possible mistake?

WilliamM2

Are you saying there is no black wires to the tweeters? If there is just take the advice above and connect to positive.

You could follow the wires down to the crossover, the PCB is marked (+) (-), but you will need to remove more drivers to see them.

Hello WilliamM2,
yes there is a black wires. I Just connected them to red pins on the tweeters. Hope that the Polk in the 90's did the right connection down to the crossover. I checked the system also with a Sheffield Test Cd and it seems allright. Hope that the two tweet are in the right phase.

It is almost always a mixup at the driver, as the crossover connections are molex connectors.
