Inverted Phase Preamplifiers with REL Subwoofers


I understand with use of an inverted phase preamplifier, it is necessary to transpose your speaker wire connections from positive to negative and negative to positive to correct phase.  As REL subwoofers are connected downstream with a Neutrik (high Level) connection at the speaker terminal do you have to reverse the wiring?  With normal phase Yellow and Red wires are connected to the positive terminals and the black wire is grounded on one of the the negative terminals. (3 wires total) The REL also has a phase switch (0 to 180) but is this the solution?

The absolute phase or polarity of the preamp has nothing to do with how the sub is operating- the latter has everything to do with your main amplifier.

use the high level inputs on your subwoofer.  

subwoofers seeing the same signal as your amplifier sounds best in my many trials and systems.
