Oh for Christ's sake, have they not taken this thread down yet?
Yes, you can improve Magnepan's all day long. Risers, better stands, removing the fuse from the tweeter circuit, hardwood or hardwood plywood frames, better crossovers, a second layer of foil tape over the existing one to raise them to 8 ohms, beveling the opening in the MDF frame and adding hardwood on the outside of the frame so you don't have to use white gloves to move them, removing the bottom and adding an open baffle sub underneath…. And on and on and on. The 1.7i's going down to 40hz, as per their specs, is a joke. They have a large bump at 70hz, then fall off to almost nothing.
After a million years, they still have square corners in their panels, which cause an inordinate amount of unneeded harmonic distortions in the film requiring them to pin the film to the backplane in several spots, that holds the magnets, with plastic buttons and screws. And those buttons placement are not uniform, even in pairs.
Their primary goal is to be cheap. That definition of quality components and audiophile are seldom used in the same city, let alone sentence.
You want Maggie’s? Buy the LRS and use a good open baffle sub as a base and you’re golden. Otherwise anything else in their line gives you the finest mid bass midrange and an ok tweeter.
