Why is the turnover on maggies 1.6QR so much?

It has been several years since I owned Magnepan 2.7's. At that time the ribbon was a true ribbon tweeter as is in the Maggie 3.5, 3.6 series, and sounds much more open on top than the 1.6's. I've auditioned the 1.6 and agree they are a great value, however, the older III series resolves upper frequency details and sounds more balanced. Bass, to me was and remains a stong limitation of the panel speaker. This includes the Maggies, Apogees, Martin Logans, unless you go to a hybrid with cone bass driver, then the weakness becomes getting the integration correct. Magnepan has a great product, but like all else in audio, it is the trade off of strengths and weaknesses that must be balanced. Many who purchase the 1.6QR find the weaknesses of speaker size, room integration, placement, ancillary electronics, and, wife acceptance as too many weaknesses to settle on them long term. If you notice, most turn within 6 months to 1 year. Again, it's a subjective and personal choice.
