Dave - just one thing more - if you take a look on the speakers 1 & 2 (like in neolith post with MMG schematics) which terminals are negative and positive for bass and treble panel ?
Is it on speaker 1, tweeter section "-" "+" and for bass " "-" "+"
and on speaker 2, bass section "-" "+" and for tweeter section "-" "+"
If yes - i'm fine - if no i'm lost.... :-)
Follow Ups:
Yes, that would true.
That shouldn't be confusing because you can tell which side of the speaker the tweeter is on just with visual observation.
Dave.
O.K - my project is finished.
Maggies are back to life and i'm happy one to enjoy their great sound.. !
12QR are my first Magnepans - i was worried about bass reproduction - but there is nothing to be worry about...
OK, very deep bas could be more audible but what we have, is so good quality and so well integrated to the rest of the frequency that i don't have a feeling that something is missing - so i don't need subwoofer.
Once again big thanks for your patience and help !!!!
As should be. Great to see that you got it right! Bass from Maggies can be tricky to get proper in some environments. Evidently you got the best essence of it...not "a ton of bass" just "more of the detailed & textured lower bass"?
You don't mention the fabulous imaging that they can deliver in many places...but give them time for the parts to break in and perhaps this will start to show up.
BTW, if the time comes when you want to push the 12's further, we'll be around.
Enjoy!
Don't be afraid to experiment with placement of you Maggies. Keeps notes on distances to the front wall & side walls. When you hit that right spot, it's Maggie Magic time ;)
LOL! Rickey, "magic" is right. However, you do remind me that sometimes we have to "build up the proper location". Also, imaging can be easily thrown off by other factors.
Still, when it all falls into place, it IS magic!
i must admit, that Maggies resolution and in the same time lack of sybilants or any other harshness is magic. It is not easy to match this level of presentation ... and this stereo image....vocals....
I spent some time with positioning but it looks like i was lucky - just one day of fooling around the room and i've got sweet spot.
Now i wonder how higher models sounds... :-)
BTW - a question for Maggies experts - how would you rank MG12 in beetwen other Maggies..?
I'm just curious where the improvment is most visible (audible.. :-) )
aha - just one more thing - i decided to keep this "bad" fuse in the cicuit - just in case if too much ampers would like to flow through my semi ribbon.... is this worth to use audiophile grade fuse instead regular one...??
If your room allows it, you should try the HK/Limage setup. Quite a few of us have tried it to great effect. It works best in shoe box shaped rooms with wall length proportions of 1.1 to 1.4 (1.3 seems best) and 1.6 to 1.8 (1.63 or thereabouts is best).
Square rooms and 1:1.5 and 1:2 don't work well for the setup.
The speakers are set on the short wall and
pulled about 40$ into the room (e.g. 8' in a 20 ft long room.)
and setup 1 ft or so from the sidewalls
with the tweeters in
and the speakers facing dead forward
The listening seat is approximately 2 ft from the back wall.
You can look at setups worked out by Mark Man and Wazoo among others. You need to fine tune all the measures, but the initial figures usually do quite well.
well .. this is not available to me - my room is not that long....
BTW - actually my room is nearly square and i' surprise about quality i quantity of bass MG12 can offer...
I will give a try to the audio fuse... and write here about my impressions..
Cheers !
I'll leave the other stuff for later and/or for others; but regarding the fuses, please consider this for now.
For reference, QR tweeters are pretty darn strong. My MMGs have always had the fuses off*. These days, each tweeter has well over 200 watts of power connected directly (under line-level bi-amping). Despite my dumb errors in the past (full range signals by accident) they are merrily tweeting on.
If you cannot hear a difference between the current fuse and a straight wire in its place, worry not. Leave the fuse on. OTOH, if you do like it more without the fuse, you can leave it off at this stage and keep the wire. Then you could perhaps invest on high-end fuses. They are pricey and will be overkill in most cases. That said, you do live in Europe...replacing or fixing the 12's is not as easy as it is here.
*(this may not be wise or advisable on the high-end true ribbon tweeters. Still, some of our inmates do run true ribbons without a fuse...very carefully!)
