  You may have a room with too much reflection such that reducing the tweeter output restores the balance. If you like the stock resistors, wait until you hear some good ones! My favorites are Caddock power film resistors in flat packages. You have to mount them on heat sinks, and damp the heat sinks against acoustic vibration.

  OTOH, you may have RF noise entering your system through the speakers. Magnepans make good antennas, and adding the resistors may provide enough inductance to reduce the RF noise level. In this case, you could replace the resistors with RF chokes, such as the JW Miller 5522, and get even more benefit.

  All this can be done without modifying the speakers, and you can always put the original resistors back to obtain your baseline performance level.

    Al,
    I would like to try the RF chokers in my 3.6R. Could you please tell me where I can get JW Miller 5522.

    Many thanks.

    • Not a stocked item anywhere I've looked on-line. - Al Sekela 14:40:36 04/23/07 (2)

      Sorry that I can't direct you to a stocking distributor. All the distributors I know of show it as a non-stocked item, with a large minimum order.

      • Ahh, I found it at coilws.com with mini order 5 (nt) - MichaelWang 20:03:35 04/23/07 (1)

  I restored a pair of 1.5s and found them wonderful but slightly bright. Added the one ohm resistors from Maggie and voila! Perfect. I marvel daily at how good they sound.

• Uh, that's why Magnepan included the resistors. I used - HenryH 05:17:53 04/19/07 (0)

  them, too, with my MMGs before I had my then listening room carpeted. After laying the carpet, the sound was a bit dull and lifeless. Removing the resistors restored the proper balance.
