All Magnepan speakers require a lively back wall to generate the proper sound at the listening position. If the back wall is too damped, it will muffle the high frequencies. Remove any damping panels, foam, etc from behind the speakers and listen. Maggies do not respond well to rooms extensively treated for cone speakers.
My New Magnepan 1.7i's sound dull and lifeless on the top end...why?
First time Magnepan owner - 5 days old 100+ burn-in hours on them
Associated Equipment:
-Denafrips Terminator Plus
-Holo Audio May KTE version
-Pass Labs X22 Pre-amp
-PrimaLuna EVO 400 Pre-amp
-Pass Labs XA100.8 Monos
-PrimaLuna EVO 400 Monos
-AntiCables interconnects and speaker cables
-Stock tweeter attenuator jumper replaced with AntiCables level 5 spade jumpers on the 1.7i's
My spectrum analyzer indicates both speakers highs are falling off beginning at 1.25K and are 9db down from 2.5K on
Been playing around with speaker placement and room treatments for 2 days now without any remediation. What am I missing? Suggestions appreciated.

Agreed, very odd, especially since whenever some solo violin comes up at random it's actually impossible to skip or change the tune since it's so darned engaging. One thought, you have a lot of 'gear' going on here. Maggies really aren't that finicky, I recall using some of the priciest Nordost Blue heaven cable and it really dulled things down. Mostly bass, but plain 10 gauge wire sounded much better. If you are 'upgrading' anything based on cables, I'd start there, replace with more ordinary and especially high gauge stuff since Maggies like current. |

Also take a flashlight and look at the wiring near the crossover and see if you see something disconnected. I seriously doubt both panels would be a problem but it is possible that a new guy mis-wired them. Apologies for the delayed response. We have a winner! Banana plugs were inserted too far. Backed them off a 1/8", and the magical highs appeared. I must say, these Maggie's deliver incredible musicality and detail. Thanks again for all the suggestions and the fix from russ69. |
