I currently have both in my listening room, so if someone wants to make the trip to Chesapeake, VA and take a listen...

I'm setting up the 3.7i in the next few days.

3.7 Sold as of 4/10

Looking forward to your comments on how they compare. It would also be helpful if you can share what electronics you are driving them with. TIA!

[NIGHTFALL1970]

I can't wait for your impressions either.  Please tell us what albums you used (CD or vinyl) and what tracks.

Feel like stripping the socks off?
The best guess is that they added damping material to the midrange section while the crossover remains as before.

No, but I will take a close look through the fabric and report back.

This is going to sound crazy, but you might try taking pictures through the fabric with your smart phone and a very bright light source. Also vary the angle on the light and the camera lens, you may be able to see something that cannot be seen with your eyesight alone.
A comparison shot between the 3.7 and the 3.7i, front and back, might reveal any physical differences in the drivers that exist between the two speakers.

fullerf, Can you post some impressions of the comparison?

[fullerf@cox.net]

I was fortunate enough to be able to listen to them back to back in my listening room in the same exact location, tweeter in and aligned with a laser pointer.  I even stacked the deck in favor of the 3.7 by leaving them in the Mye Stands with HiFi Tuning fuses and 0.6 ohm dueland resistor.  3.7i were stock with 1 ohm resistor but fully broken is as I bought them used.  I started with the 3.7 and then to the 3.7i then back to the 3.7 to confirm what I was hearing. The 3.7i were slightly better, specifically the vocals seemed to be more forward and in front of the speaker, more 3D...  There was a richer texture to the music and the drum strikes seemed to be more natural. Soundstage extended beyond the outer edges of the speaker more than the 3.7 already do.  After listening to them back to back I would recommend that anyone with 3.7 pay the $500 for the upgrade.  I realize shipping the 3.7 back to Magnepan and back home could cost another $500.  STILL worth it!

Thanks for the review.
Were you able to peer through the socks to see what's up?

Steve, Two things... One, the white tape that we have all seen posted here before. Two, the hardware on the back is bigger. The screws will not fit through the slots in the Mye stands.

[SwamisCat]

Does this imply that Mye stands for the 3.7 won't fit the new i's? Or just fit differently?

If the latter, are you keeping the Mye stands? How would you compare the sound improvement from the stands compared to the i?

Have you guys tried the DAC amps with your Maggies?

Tommy is running a Kickstarter campaign now with substantial discounts on the new MINT.

I am going to have to modify the vertical supports to accept the bigger hardware. (Drill a hole)  Otherwise they will work just fine.

What is this bigger hardware?

[fullerf@cox.net]

What is this bigger hardware?

All the hardware on the back that holds the speaker together are larger machine screws compared the the 3.7 wood screws.

[Roger Gustavsson]

So there must be some kind of nut inserts for machine screws in the wood/metal clad MDF pieces holding the grille cloth?

Perhaps someone should ask Grant Mye of Mye Stands. He doesn't list any 3.7i stands.

My 3.7i's were upgraded at the factory and shipped to me in mid-February.  They have wood screws on the back holding the speakers together.  In fact 4 of the screws were loose and would not tighten.  I spoke with Shelia at Magnepan who said that can happen because taking everything apart then putting the screws back into the same holes, and MDF being what it is, the hole can get too big for the screw to get a grip.  She recommended a well known fix, 2 or 3 toothpicks cut to the length of the hole depth, put in there with some Elmer's glue.  When dry, the screw tightens perfectly.  Still, it was rather disappointing to see the lack of care by the Magnepan technicians who should have taken care of that when putting the speakers back together.

I would like to see machine screws back there instead of wood screws.  Because there would need to be a nut insert in the MDF for the screw to go into, which would make for a stronger attachment.  However I doubt Magnepan would go to that trouble in the upgrade process.  There are 18 wood screws on the back of mine.  Changing those over to machine screws and placing nut inserts into the MDF would be a lot of work.

Also mine have no white tape or anything like that on the back.  In reply #135 in the discussion below, there is a picture of "padding on the back of the midrange."  Mine don't have that.

This is the picture from that discussion, not a picture of mine.  I could take a picture of mine later and post it if anyone is interested.
