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

If someone add's the Axiom available resistors to cut down some of the top end on the tweeters, do they do this to all the speakers ? The VP150, and QS8's all have the same 1" unit.. Or is this just a Stereo type only fix ?

Mikey, additional resistance added in series with any sort of speaker reduces its output level.

Correct.. What I meant to ask was, if someone adds the resistors to their mains, do they or should they also consider adding those same resistors to their VP and/or Q speakers.. To keep the overall sound the same.. I would have to guess this would be a 'for sure' thing to ones VP ?

Mikey,
I had the same question some time ago and i decided to try the resistors on the VP150 as well.
The centre channel takes up a huge amount of vocals in various DSP modes and during HT play so it made sense to add the units to the 2 tweeters on the VP150 as well.
I was less concerned that the upper frequencies from the QS8s were so prominent that they needed resistors.

We were pleased with the overall effect the resistors had, which was very subtle. I would describe it as being similar to having turned down a treble knob one notch (for lack of a better or easier description). I'm not sure what others have posted to describe how the 'after resistor' modification sounds to them.

Thanks Chess, that would seem to make sense..
I left a msg via phone, and later an email, but have not received the resistors as yet.. Meanwhile I got to thinking about it and figured I might as well order up 3 sets when I call back..

if you were to add the resistors,would that change the impedance ,freq response,and power requirements?....ron

Hi Ron,

No, adding the resistors wouldn't change the speaker's overall impedance significantly, since the impedance is largely determined by the resistance of the many windings of fine wire in the voice coil of each driver in the system.

Regards,

THANK YOU...RON

Hmmm...interesting...well wouldn't it be easier to just turn down the treble knob one notch then:)--please note the sarcasm:)

Sarcasm noted.
This was actually discussed awhile back as to why using the treble knob is not a particularly great idea compared to resistors.
I cannot find the post right now. Maybe someone else can link to that.
