Axiom Home Page Forums General Discussion Technical Questions Tweeter Resistors..

I believe the distinction between turning down the treble and using the resistors was discussed in the following thread ("M60 Ear Fatigue" in the Stereo section--sorry, don't know how to post the link correctly):

Can't promise, but I think I remember that.

I think the treble dial is a "brute-force" method, whereas the tweeter resistor is more precise and selective. You're only changing what needs changing.

Whenever you add or cut via trebble or bass controls you are taking a chance of adding noise to the signal..
'Working' the sound with potentiometers has always been viewed as a last resort by all the sound engineers (studios and concert sound reinforcement) I have know.. I was always taught to do everything I could to avoid turning those knobs ! The more you crank'm over, the more dirt you are throwing into the mix..
Which brings up an interesting question, are the Trebble Mid Bass pots today digital ? Now that would be a horse of a different color..

If anything, I'd think that the added resistance in series with the tweeter should be considered more of a "brute-force" approach, since it uniformly decreases the entire tweeter output range(about 3,000-20,000hz). This might be helpful in very live listening rooms where a uniform decrease might not be too far off target. It doesn't address with any degree of precision or flexibility poorly recorded items(particularly common in pop recordings)which could use frequency adjustment on a selective basis. Tone controls are helpful and are meant to be used, but then they can be turned off when not needed. Better are the more flexible equalizers available on some receivers or as separate units.

An intermittant problem shouldn't be addressed with a permanent change.
