You need to put atleast 300 hrs on them before any serious, critical listening evaluation. To speed it up put some brown noise on repeat on your cd player to help with breakin. I also started with tweeters out but changed to inside position and the sound began to gel. I did change fuses to HiFi tuning 4a fast blow fuses. They are directional and need to be pointing towards the floor. I also replaced metal tweeter attenuator bar with a short jumper. If you are adventurous you can unscrew and remove plate on back and move the red wire from the fuse holder directly to the negative terminal and bypass fuse and tweeter attenuator. If you want to keep the fuse intact you can take black wire from bottom of fuse holder directly to negative terminal and bypass tweeter attenuator.

I'd wait until the speakers were run in before making ANY changes.
Do your initial setup than wait for maybe 20 or 30 playing hours.
readjust. Repeat until 100->200 hours or the urge to readjust passes.
Poster above likes 300 hours. Mine were about 80% at 50 or 60 hours with the balance over the next 100 or so. No beef with waiting longer, though.

THAN bridge the fuse out of the circuit and install the jumper of your choice.

I even ended up tweeters IN with toe to cross just behind my listening position. This gives a large sweet spot and good image. I also have the Mylar to the BACK not the front as issued by Magnepan. Sweet.

((to Audio connection:
I believe the tweeters are on the outside. Wrong or right?))

wrong try these on the inside you may still like em on the outside but I think you will like them on the inside better.

You still have not answered the Question
Did you try the supplied resistors in where the Tweeter jumpers go
This is more important than any anything.........
Please do both ASAP and let us know
Cheers Johnnyr

The tweeters can go inside OR outside.
You can even flip 'em backwards, so the mylar is to the back and the magnet assembly is to the front. I have mine that way now, and glad I did.

But, don't mess with anything until you have a 'baseline' established.

(I am also a week old Magnepan 1.7 owner. I am finding th sound thick(improved aftermuch placement efforts) and the upper midrange hard, Short of changing amp and pre-amp-any cost effective suggestions?)

Huh? The last thing I have found them to be is thick and hard. Light on their feet, gorgeously natural and beautifully integrated, these are some of the flat out easiest speakers I have listened to. They are revealing like many god speakers are but I have found them to sound good with even a $900, 60 watt integrated amplifier running
iTunes from a computer wirelessly! Seriously...these are truly delightful speakers and everyoe should hear them just to hear what $2,000 bucks can buy you these days.

Oh, and yes, change out that chunk of chrome metal for a nice copper jumper for a nice change to the tweeter.
