Mine had 50 hours on them when I got them...
It took another 2 to 300 hours for them to really settle in... Coherence imaging depth and soundstage... Will continue to become more apparent and focused with hours...
I threw an old set of tubes in my preamp.... And I let the whole thing run 24 seven putting on a total of 600 hours... I was doing this for the cables that needed those kinds of hours...
But the speakers really bloomed after that 250-300...
Push those bass panels out to the side walls with in about a foot to 8 inches... And just inch them slowly till everything snaps in..., In my humble opinion...
I would start very close to perpendicular once you start inching them in to get your soundstage and center image in focus... Before you really start pushing the toe in...
Spatial cues and coherence are what really start showing their colors early with improvement...
Really happy for you man... They will improve....
After that 600 hours they were awesome... But excellent after 300hrs...
Good luck feel free to contact me off-line if you have any other questions particular to the 3.7's
Thanks

Thanks guys. It is reassuring to hear imaging, soundstaging and depth improve with break in. I always heard about bass needing time, but was surprised at what a mess soundstaging was at first. I can hear it improve with every ten hours or so. I now have about three full days, and it is still improving.
One of my favorite tracks is Moonlight Serenade by Laurindo Almeida and Ray Brown. Until both instruments float cleanly and coherently behind each speaker I know the imaging is not yet perfect.
I will resist going tweets out for a while longer. I have a shoebox room and can't get the tweets too close to the side walls. Also, as a personal preference I react negatively to my speaker getting in the way of the image. I need the image to float in space behind the panels. Tweets out destroys this illusion for me. That is just me. (Or is it? Does anyone else get bothered by the panels getting in the way of the stage?)
However, all that said, if I can't get the tweets in to work in a few hundred hours and various configurations. I will give tweets out a spin.
First let me say my room is 17x17 'box shaped' so it's a challenge to begin with.
I recently did a slight toe-in (roughly 5°) on my panels with them positioned about 29" from the left side wall, and 36" from the right side wall. There's a wide space in-between (about 8' apart) and about 9' out from the front wall. I sit about 7 1/2' in front.The imaging can be down right spooky at times; I had a friend over visiting from out of town recently and after seeing my system he asked "what are those?"....I replied: "well sit right here", and placed him dead center on the couch. Cued up was Billie Holliday's "God bless the child" performed by none other than Aretha Franklin herself (1962)...the song starts out with orchestra on the left, orchestra on the right, no real depth per say, mostly emitting from the panels themselves..(remember this is 1962 'stereo') but almost as if on cue, an aberration of Aretha seemingly appears dead center and begins to sing her version of this timeless classic as only Aretha can.
My friend simply stated 'holy shit'....
I'll take that as a thumbs up ;)
*note- I used the term 'aberration'; a word usually associated with ghost, spirits, etc.,. but I am well aware the Queen of soul is quite alive and doing well ;)

Perhap 'apparition' as opposed to aberration?
Too much is never enough
I need to update that my 3.7i's are breaking in and loosening up nicely. The soundstage and coherence is now comparable to my original pair and still improving by the hour. They no longer require toe in just to sound decent.
My current set up is almost exactly the center of the room (about ten foot from FW). The tweets are inside about 7.5 feet apart and 9.5 feet from my ears. Very minimal toe in.
Still experimenting...
Thanks for the update SC...Any guess on the hours logged on them so far???
Mine are located very similar location, and distances apart...7' tweeter to tweeter, tweets in...
I am somewhat relieved that things are improving as I "stated"...they should keep improving...
thanks again

They continue to cook in nicely. There is simply no way to overstate how dramatically these speakers improve over the first 175 hours. Everyone talks about the bass improving, but the biggest and most important shift to these ears is in coherence and image specificity and depth.
Rachmaninoff sounds amazing right now.
"Rachmaninoff sounds amazing right now."
There hasn't even been the slightest peep out of him since March 1943.

IMHO, early on they give you a "peak" at their potential...as the hours pile up they reach a point where they start to exceed your expectations...this model of Maggie is just like all others...play me loud, feed me lots of good clean watts...and I will reward you with beautiful music... then the sad inevitable bleak truth starts to sink in...all of sudden you start to look at everything upstream and go HHHhhhhmmmmm....I am in a cable phase currently...my next major upgrade is DAC/Server...still haven't found what I am looking for...
Thank you for the update...great news...
take care

Tweeters in or out, your images should still float and be located correctly within the soundstage...as I have commented before, in my room, (12' X 18' X 8' partial wall behind me, then open to dining and kitchen...condo living), tweeters out had this exaggerated Atmospheric way outside the walls sonic presentation...cool, just not as musically correct...
My experiences during break-in were just not speakers, but new speaker cables too...so I feel my original comments needed to be weight with a grain of salt...Zu Audio Event speaker cables...take forever and day to break-in...that is why I left rig running 24/7 for 600 hours...
After that break-in...3.7's sounded like a single driver...separation of the instruments with-in the sound stage has been amazingly focused and precise...
You have me very interested as you go through this process and I appreciate you keeping us posted as things proceed to change...
One of my reference tracks that I use for sound stage depth and imaging is DSOTM...track 2, clocks and cymbals...they ring and float from 6' in front of the speakers to 6' behind the speakers...as I have said before on this board, I can walk around IN the sound stage and just about touch each one of those cymbals...
Good Luck
Thanks again...
Mark
Thanks Mark.
Just to clarify, I am not suggesting that one should have the tweets in or out. I am just sharing that for me, the illusion of instruments floating gets cognitively disrupted by the speaker being in the way. I am a sucker for images floating free from the panels.
I hope when mine break in that I will get this type of stage that you describe. My older Maggies tended to only project images behind the speaker plane.
I am currently listening to Chis Isaak, LP, Speak of the Devil, great CD, music and sonics...I do now GET what you were saying about being behind the screen door panels, (3.7's)...but even on this album the panning of the guitars, Hershel's strat is stage left and in front of Chris's guitar and vocal...about even with speaker location...but it does not sound that 3.7's are in the way at all...could be just me...
Thank you clarifying what you meant...
Things will get better...
take care
Mark
