Magnepan 1.7 too bright, HELP

I think you are right about the new maggies being bright. I heard the 3.7 yesterday and like them but they sounded a bit thn and bright to my ears. were hooked up to some nice ARC gear too. Maybe they were not broken in yet? I really like the sound of the older Maggies more. To me the 12 and MMG sound much more relaxing to my ears. Sure they don't have the hyper detail or bass and treble extension as the newer 1.7 and 3.7 models have but the just seem more musical to me. And can sit back and relax not worried about any nasty peaks or sibilance to them.
My theory is that many new products are becoming brighter. I could be wrong but i think that many of these icon designers are getting older and they don't take into account there loss of hearing in the upper ranges when they design there new speakers. Hence the brightness. Just a theory guys.

I suppose if you find it acceptable to compromise you can use the resistor.. i did that initially but basically that was akin to using an equalizer... the treble was lower, out of balance with the midrange. Have patience with figuring out what's wrong in your system outside the Maggies... the solutions will bring you closer to a "you are there" level of playback.

Have you tried flipp'in them around and listening to the pole piece side?

Take you 5 minutes and you'll be surprised. in a good way, I hope.

The panels are NOT the same front and rear. The pole piece to the listener is the way they were shipped until sometime in the '90s.
I prefer the old way, like my original MG-1s

Don't screw with anything until you try the flip.

(((I suppose if you find it acceptable to compromise you can use the resistor..)))
Suppose???
WTF Resistor is supposed to be installed to begin with....
Most all rooms need the supplied resistor
Its not a compromise.....
Its an important part of the set up.
Every room is different having this flexibility with different value resistors and experimenting is the right way toward a solution.

sorry, audioconnection, thats not science. A resistor in series will cause a dB drop thats fairly flat between the crossover point and natural frequency roll off of the tweeter. That means you are using a resistor as an equalizer. If a room is reflective, you kill the reflection with wall hangings, not damage the tonal balance of your speaker.
Calling it bright is a misnomer... its a new level of detail and unfortunately exposed in that detail is distortion thats irritating and which can distract your attention from the additional good you hear until you clean the cause out of your system.
