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.
Good design approach or not, it's hard to argue with success. No one speaker or component is for everybody.

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 ["Additionally, these resistors can be used to tailor the output of the corresponding driver to overcome tonal balance issues that result from room acoustics."]. 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).
That could be easily accomplished, without running the resistors near their limit and using them as fuses, simply by using resistors having the same resistance values but higher power ratings.

That's standard practice when incorporating a resistor (or any other circuit element that dissipates power) into a design. The maximum amount of power it is rated to dissipate (i.e., to be able to handle without getting too hot) is considerably "derated" relative to the maximum amount of power the design is expected to require it to handle.

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.
I believe nearly everyone can relate to the occasionally "grumpy mood" type of day. Keep in mind that no one has questioned Dave Wilson's talent or the obvious success he's earned with his speakers. It's only curiosity regarding an unconventional use of resistors in an audio product.

Accepted and thanks for "manning up" the net is full of "Keyboard Ninjas" that post utter nonsense and insults, hiding behind a moniker with no consequences.

I don't know why the Wilson team has chosen this approach, which to me and to others here seems questionable, only they can answer that question.

One thought can come to mind, they simply do not want a driver failure. Because of a marketing position they view that a blown resistor is more palatable to their target group than that of a driver failure, even if this solution comes with some sonic degradation happening over time. Before you and Polk get all puffy again, there is no way this does not happen because of the "resistor fuse" heating up over and over again, and eventually failing. If a resistor is used as a fuse it will have to be run too close to its maximum power handling capabilities even when playing moderately loud to have any effect to that cause.

In your example you were cranking it up while zipping wine and the speaker gave up, had the resistor had adequate power handling you would have rocked on and that would have been the end of it. I would not worry about damaging drivers, if they are behind a properly designed crossover they are pretty sturdy.

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.

When you are buying a Wilson speaker you are buying more than just a loudspeaker you are buying a status symbol. They more than anyone have been very successful at conveying that message to their potential group of customers. They come in very fancy cabinets, have leather bound manuals etc. All which of course have nothing to do with that actual purpose of the product, which is to make sound, but it certainly enhances the perception of the speaker.

That of course also the reason that you and Polk react the way you did "how dare someone tell me that my loudspeakers are not perfect ! I was told they were"

Good Listening
