Mine had 50 hours on them when I got them AND they were 3.7's not the i's...NEVER had a hint of brightness or shrill...
The 3.7's are the first Maggie model with the true ribbon tweeter I have owned...so other than a dealers or friends home is where I have heard true ribbon models...I can not really comment...
What I can comment on, is the differences between the 3.7's and the i's...smoother top end, rounder bottom, more coherent, (if that is possible), they play bigger...soundstage grew in all directions and images were more defined within that soundstage...this is just IMHO...
thanks

Swamis, are you running your DWM's? And where are they current place???
Follow Ups:
Today I am not running them, but it depends and I would say a fair estimate is that I use them about 95% of the time since getting the i's.
The reason I am not running them today is that last night I shifted back to a tweets in configuration to try to get a little more high energy sparkle. As of this AM I have a fairly standard Limage setup going on at 40% point of the room, panels perfectly flat. This gives more than adequate bass. The DWMs were overkill.
I have tended to run the i's with tweets out, toed in, about two feet from side wall at just under 40% point of room. This has awesome bass -- but is just a tad light without the DWMs and just a tad heavy with them. Always trade off.
The exact configuration of the DWMs depends upon the details of how I am configuring the main speakers. In general I use the recommended set up by running them along the side wall (perpendicular) about 12 inches closer to the listening position than the mains. However, six to twelve inch variance around this can smooth out bass, as can setting one up let's say eight inches closer and the other twenty inches. With the DWMs, you can get really smooth mid and upper bass -- or the antithesis thereof. If you pursue smooth frequency response excessively though, you can screw up other things, such as timing. I always use the resistors and cheap speaker wire to minimize output so the bass doesn't become too thick. Oh, and you can also smooth the bass by placing the panels at different heights. It's kind of cool.
After spending a year and a half with the bass panels in three rooms with two different three series, my summary is that they are great at adding punch if needed from 80 to 300 hz. Extremely noticeable in acoustic bass, cello and drums.
They have never made a lick of difference in the low bass. None. Nada. Zero . Zilch. They don't put out anything of note below 50, nor have I ever noted any synergy of the panels reinforcing the mains. There might be a tiny bit of reinforcement of having the DWMs as wings to the mains, but this violates the requirement that the bass panels be time aligned ahead of mains. Doing so will primarily result in not low bass, but an unlistenable reinforcement of the upper bass and lower Mids (peaks at 160 to 300 hz). I get the same upper bass problems if I try to place the panels freely out away from walls in middle of room.
These are not subs.
good write up! Answers a lot of question I've had floatin' around in the back of my mind.
Swamis...THANK YOU...
You are moving those DWM's on 6 axis's...front, back, left, right, up and down...AND in three different rooms...golf clap...
Here is what I find amusing, interesting and ONLY happens when you live with a product...
Amusing: All we will try...go through and fret about chasing that "SOUND"...here is a quote from you "As of this AM...", that is kind-of funny when it comes to speaker placement...
Interesting: How these Di-poles, in all their forms, play the room...AND how to a certain extent, we can place them to achieve our own personal sonic tastes...AND all the variables that come into play...as you say..."Always trade offs..."
Only happens when you live with a product: At a dealers listening room or show, IMHO, you get a taste of what the product sounds like...90%+ of the time the dealer does not have the same frontend, cables, room...yada...yada...yada...even an in-home trail for a few days, IMHO, won't give you the full experience of living with a product for an extended period of time... (hence, why I buy and sell on Agon...)
I have only heard the DWM's with the Mini's, and both times they were very disconnected from the mains sonically...but a very intriguing product...
Thank you again for taking the time and posting your experiences...very cool...

I agree completely. There are several awesome audio retailers in Chicago and San Diego which I frequent. In only one case have I heard Maggies set up well.
I bought the DWMs to go with my IIIa's. If I had the 3.7i's I doubt I would have bought them after the two week loan which my dealer provided. They synergize better with the older model.
And I agree The DWMs can easily become disconnected sonically, especially in smaller rooms.
Oh, forgot to mention that the 3a's need the panels more than the 3.7i's. This is because the 3.7i clearly boosted upper bass at the expense of the much better low bass of the 3a. With the 3a you get the much better low bass and the mid and upper bass reinforcement of the panels. Best of both worlds.
