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+ ?

@delfincek thanks for the suggestions.

I few weeks ago I have already contacted Hifi Collective UK and now have the full price of the Mills, including custom taxes. Meanwhile, I already have 1R, 1R5 and 2R2 Mundorf 10W resistors to try… the 1R5 is doing such a good job smoothing the treble that I am proceeding with the room positioning set-up… until my mind blow up!…

As for AliExpress, well don’t mind me saying but that is a route I don’t want to take, for many reasons. Those speaker cables, for example, are the type of product that I fail to be interested: a copy of the Nordost. I feel that is the looks that they are after without having the materials and technology… Sure, the price of the original is absurd, not only to my financial capacity, but in general, but some way it kind of reflects the R&D, technology and materials used, I can’t believe that someone offered something similar at 1/20 of the price…

I am not saying that they sound bad (or good), just that I can’t invest in that kind of product.

Also I am uncomfortable to bypass the fuse. Sure, it must do more harm than good but it is there for a purpose: safety. I have bought an AMR fuse designed especially for the Magnepan, but I will only tested after finding the correct LRS+ position in the room.

One interesting thing about speaker cables: when looking inside some good high current amplifiers (Plinius, Perreaux, Muse) we can find the same type of cable design - connecting the binding posts to the main board - of the Van Damme L-OFC 4mm that I use. That makes me stick with it :)

Hiya,

interested to hear a feedback if you get Mills and compare it with Mundorf resistors. Also pretty much interested for feedback when you get AMR fuses and you try to upgrade the default ones.

Van Damme is used in various applications. Also Harbeth use them have their speakers too. Btw I use Van Damme Hi-Fi L-OFC on my subs connected to High Level inputs.

Best wishes, D.

 

Currently, I have the feeling that I am in a middle of something with the LRS+… on one side there is the speaker positioning and on the other the amplification.
In some degree, the evaluation of one is connected with the other.

The Rogue RP-1 / NAD C275 BEE pre-power combo is performing very well and led to a new position of the speakers that finally I am getting a good depth and soundstage… but the treble continues a bit hard and compressed on some recordings.
With gentle acoustic music I am in heaven. 
With busy recordings with brass instruments (for example) it is not pleasant at all.

Also the LRS+ are really “power sponges” on some recordings, with the volume knob seeing untraveled territory… uff

Note: the speakers are on aftermarket stands, more or less 60cm from the side walls, 130cm from the back, toe-in pointing behind my head and tweeters on the outside. Treble resistor Mundorf M-Resist Classic10w 1,5 ohm.
Speaker and interconnect cables are Straightwire Encore.

 

For anyone wishing to try a bunch of different value resistors check out JF components they have many audio quality of under $2.00 each, I just placed an order myself. They also carry speakers and other audio components.
