Wilson Audio MAXX resistors


I am about to replace resistors on my MAXX-1 which is in use for the last 10 years. There is no information in the instruction manual and i have absolutely no idea which resistors are to be used for mid/hi freq.. Does anybody have any information on the effect and procedure for resistor replacement/selection.

I had to replace my resistors. I accidentally turned the volume to high after a few glasses of wine. Sound became muddy and imaging was reduced. I thought I blew my tweeters but it was just the resistors. Changed them and everything snapped back.

Did they say how often you should change the reisistors?
You think that resistors may act as fuses? Ask Dave Wilson, I'm sure he'll know.

I am pretty sure they do.

Midrange and Tweeter Resistors
The Midrange Level, which consists of two 3.2 ohm resistors in parallel, and Tweeter Level, which consists of two 1.6 ohm resistors in parallel, resis- tors provide precise level matching for the midrange and tweeter drivers correspondingly. The resistors also act as ultra high quality fuses which open be- fore a driver can be damaged by excess power. See Section 6.0 for details in replacing these resistors in the event one of these resistors is damaged.
Additionally, these resistors can be used to tailor the output of the corresponding driver to overcome tonal balance issues that result from room acoustics.
Sorry but I have to laugh at some of you guys. Looks to me like the resistor plays a multifaceted role for the Wilson speaker. Read the last sentence in my post. Also, there is a speaker review of the new Alexia where the reviewer found the speaker too laid back, I believe, and changed the resister (through Wilson I'd course).

There are a bunch of ways to skin this cat otherwise we would all have the same speaker and it would be mde by the end user.

Sorry Peter but your statements that this is not sound design makes you look like a chump and a guy desparate to sell his Montana speaker that only the Elk find appealing. Not trying to be mean but as a manufacturer you look self serving.
First, my apologies to PBNaudio. I was fairly grumpy yesterday and was out of line with my comments towards you.

So here is my question..... Why have this poor design as some suggest not in one speaker but in the whole line? Also, not just this years model but prior series as well.

I am not an engineer so I am not about to attempt to discuss technical issues but I really doubt Dave just got stupid or careless in this element of his speaker design. I am sure that it has everything to do with sound, flexibility, and technical issues related to the overall speaker design.
PBN wrote "A high end system from my point of view certainly should be able to be played loud and proud at times without the risk of it shutting down. That being said gross abuse, amplifier oscillation etc, can and will cause driver failure even with the best designed crossovers. "

I agree. I do play loud and proud often but in this instance I was drunk. I had the remote upside down and thought I was turning it down when I was actually turning it up. I pushed well pass any listenable volume. I think I would have blown my tweeters without the resistor failure.

It may indeed be a marketing ploy or just a way to save the customer money when they do something stupid like I did. I think the tweeters are kind of expensive.

I must say that the degradation of the resistor over time from normal use is new to me. In my case it was unintentional abuse.
