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+ ?

The supplied 1&2 ohm resistors kill the top end. That is why the Audio Connexion option for lower value resistors is very low cost… under $75 and likely to make a noticeable improvement.

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.

Let me just say that I went through multiple amps and two preamps… and each shaped the sound in their own way… but it was the 0.25 ohm resistors that really dialed things in…. my room is large and somewhat live.

I find that the 0.25 ohm resistor has zero impact on detail, sounstage, imaging… from what I’ve read just a very, very gradual roll off from about 800hz up which in my case tames the slight brightness/sibilance in a way I can both live with and afford.
