It looks like it's possible. From the manual:
Section 3.4—Resistors Midrange and Tweeter Resistors By removing the large aluminum back cover on the rear of the woofer module of your Sasha DAWs, you may gain access to the resistor plate. These resistors serve several functions. Note: Only Wilson Audio replacement resistors should be used in your Sasha DAWs. Changing the value or brand of resistor will have a deleterious affect on the sonic performance of your loudspeakers and will void your Wilson Audio Warranty. The Tweeter Level, which consists of two 6.0 ohm resistors in parallel, and Midrange Level, which consists of two 4.8 ohm resistors in parallel, resistors provide precise level matching for the midrange and tweeter drivers correspondingly. The resistors also act as ultra high quality fuses which open before a driver can be damaged by excess power. Additionally, these resistors can be used to tailor the output of the corresponding driver to overcome tonal balance issues that result from room acoustics.
Wilson Audio Resistors
Greetings,
I'm wondering if anyone has matched resistors on Wilson Audio speakers.
Sasha DAW has a pair of 6 and 4.8 ohms for highs and mids respectively.
Due to acoustic problems in the room, I need to increase the treble and for this I could combine the resistors like this:
Join a 6 resistor with another 4.8 ohm resistor in parallel to end up with 2.66 instead of 3 ohms; with this you would get a desired increase in the high notes.
My question is if this change from the original Wilson Audio resistor values can cause damage to the speakers.
