Magnepan LRS+ resistors on the tweeters… which?

I have a pair of LRS+ and after playing with the set-up positioning for a while I have finally found the spot where everything aspect of the sound is right apart from the treble: it is simply too high, and is tiresome after a couple of records.

But Magnepan knows it and fit a pair of sockets to allow the user to play with 10W resistors, ranged from 1 to 2 Ohm.

The resistors that come with the speakers are not the best and some users refer that they affect the sound too much.

So I wonder, what are the best resistors to fit in the LRS+ ?

I’m not familiar with the Magnepan setup, or the resistors they provide, but many wirewound resistors have an unwanted inductance byproduct due to how they’re wound. You should be better off if you can find non-inductive resistors of the same value...many of those are double wound in a manner that cancels the inductive byproduct.  

The ones I'm currently using in my speakers for tweeter attenuation are old Dale metal body 25W 3 ohm designated with an "NH" prefix.

I went to the Parts Connexion and found the same ceramic resistors that Magnepan provides and bought matched pairs 0.1 ohms, 0.2, 0.3 and so on up to 0.8… they are very inexpensive and then find which value gets you the sound you want.

I think @snapsc has the right idea. Have a range of values to swap in and out. Listen and possibly even measure to get the sound that is most pleasing to you.

Why not a pot?
