What's Up with Magnapan at Shows?

The difference in the published specs between the 3.7's and 3.6's are I'm sure accurate, and the difference may well be in the crossover. I can tell you that I am most happy to give up a little between 37 and 34 hz in order to receive the benefits of the new crossover. The new series crossover is much smaller, but it is a much better crossover in many ways. In either case, if you want to fill out the 20 to 40 hz region you are going to need a sub.

I'm not privy to their R&D department's doings but the .7 series is pretty darned good.
The demos at the shows are timed so they don't keep the next group of people waiting which would be rude.
The dealers have the luxury of handing you the remote control and letting you take your time, shows are different.

Sounds like there are some axes to grind in this thread. Kind of weird, in an industry of manufacturing components in China, you have a company that has refused the temptation for big profit increases to stay in the US. Haters gonna hate I guess.

Getting the low end response of the six foot Magnepan's does not usually happen in the many systems I have heard. The room and objects in the room must be just right. The 3.7's in Valin's and Hp's rooms do not do much below 45 Hz! The IIIa's and 3.6's do go down to 30 Hz in most properly setup rooms. 10 to 15 Hz is a huge difference!

How many other speakers manufacturers use a series crossover? It is a poor design choice.

Box subs with Magnepans never give coherent low bass, that is no solution.

Bass reproduction below 30 Hz is a mess in the home, due to uncontrollable peaks and dips! A flat response is not in the game.

Besides there is not hardly any missing musical info below 30 Hz! So just avoid the inevitable frustration, and only go down to 30! The IIIa and 3.6 will, and the 3.7 won't. Why is the 3.7 better? I do not buy the Hype!

The little, extra, bass panel attempt at improvement is BS!

Donc55, It is interesting to observe the bewildering array of reactions to the 3.7's. I have done nothing special in my 15x19x8 listening room. Maybe I just got lucky. On the other hand, when I auditioned the 3.7's before purchase, the room was a completely different room. Larger, with the Maggies along the long wall instead of the short wall. The salon had gone to a great deal of trouble in setting up the room. Of course they sounded good in that room. But other speakers, not so much. Including the highly regarded Aerial 7T's, which certainly go much deeper than the Maggies. In my humble opinion, the 3.7's are better than the 3.6's by a wide margin. More musical, certainly more coherent. The crossovers in the .6 series speakers could sound pretty awful sometimes especially with french horns and female voices. Ice picks in the ear drums bad. Sorry man, its not hype. I've been living with Maggies for 23 years. The 3.7's are the best Maggies I have heard without going into the tympanis or 20.'s. I never heard the IIIa's or 2.6R's, but I certainly know the 3.5's, 3.6's and 1.6's. The 3.7's are better than the 3.6's to my ears.
