Maggie LRS so ridiculously good

Manny use Class A to their magnapans. With good results. 
As the manufacturer says the important thing is: 

Class A/B amplifier designs that come close to doubling power at 4 ohms have a long and successful track record.

(And class A is always "on" and delivering)

I bought a pair to primarily have a total different type of speaker that i could switch back and forth between a panel and my box speaker.

It is a dedicated rather big 2ch listing space. With treated with thick absorberas and 2D diffusion behind the speakers all symmetrical. I am using a fairly near field setup there I am ~2m and sometimes closer distance from them (Not so much interaction with the room). Probably why I am happy with 5w class A. ;) I am primarily a sound stage guy.

The box speakers I upgraded with all bells and whistles that we don't even see on higher end speakers (with several thousands of dollars on their price tag).

Got the magnapan home set them up. No tweeks and just played some songs in standard configuration. And we're surprised that they sounded way better than my box speaker at this starting point!

My thoughts goes like this: 
I thought that I had hifi and good sound. But the magnapan showed me that I were wrong and what good sound is really like!..

Today I know that my beloved box speakers will not be used again 🥲 that were I not prepared for at all. And I will never look at a box speakers in the same way as i have done previous.

When it comes to tweeks one that benefits LRS/MMGs is to rise them so that the middle of the driver is at ear level and in center of its directivity (probably more crucial when you are closer to them).
Easy to test just sit up on your knees at sweet spot and listening what happens when you lower yourself by lowering your rear end towards your heels so you sit down and are more in the middle of the driver. 
You should hear a big improvement. Then it is easier to be motivated to rise them when what you will gain is more reviled.

Another tweek from the owner and manufacturer is to make sure that the left and right side of the panel is at equal distance to the listing position. When the tweeter is on one of the sides of the panel. Then it will bring the tweeter and woofer on the same parallel plane towards your sweet spot.
In other words if you have your panels parallel to the wall behind them then the arrival time will be different between the two drivers (again probably more important if you are like me rather close to them).

In conclusion if we do not sit far away with a reflective coffee table between sweet spot and the panels and other compromises in my opinion. Then you will find hifi nirvana with almost no effort even with the smallest panels. And my 5w/Ch shows that it is not about the power as such and it is more about doubling down than anything else.

If the bass is adequate or not from LRS/MMG?

I have the all the stuff for measuring with a calibrated microphone. Running sweeps for a couple of years now on my and several audiophiles friends requests.

For the old MMG in my room setup far from walls. I see that the frequency response goes down to ~50hz there it is dropping like a rock.. So MMG in my room is not playing anything below 50 Hz.

Yes, I could also say that "oh, it works for X type of music." BEFORE I knew better..

How can i know that playing down to 50 Hz is not enough?!

I have integrerated with a DSP, measurements and for example correction with PEQ with other things, that DSP is only controling my two 18" open baffle with a separate amplifier.

Even when it is only the bass and it amplifier that the DSP is controlling.
That DSP is doing 6 DIFFERENT duties/optimizations! (No DSP on the MMG)

But to get to the chase. I can then enable the bass amplifier and not the amplifier to the MMG. So I can clearly only hear what music content there is in the bass despite:
1. The crossover point is in the low range of 53 Hz and below
2. At 53 Hz it is a very steep slope of 48 dB/octave

So more or less only playing frequencies below that the MMG can not create and nothing else I can TODAY say with confidence.

That there IS stimulating music information EVEN on a Jazz trio (acoustical instruments!).
And on LP for example that everybody knows "Dark side of the moon" and we know there in the background there is a low rumbling "hart beat" sound.

Yeye everyone has heard that you say.. But actually there is several more "hart beats" sounds that is lower in level AND on couple more tracks than you probably did not know of. When those is not apparent and not played by a normal system.
Yes there is more on the d a r k side.. ;)
(And that on a LP!)

(Remember my subwoofers plays lower than my cartridge and tonearm resonance frequency! So you guys and girls that know what a rumble filter is can as you already suspect understand that it is much needed. My DSP is doing that duty also when it is needed during LP playback..)

But those MMG are gold! They can do THINGS that I never had heard a speaker do.

@chopandchange 

Yes I still have the MMG.

Things that I have done since my post old post here in the thread.

As I said I crossover the MMG at 53Hz there the Maggies roll of.

 

I put up my super upgrade bookshelf speakers and could do A/B comparison the MMG were better in every way you name it.

 

Expect in one area!

I hade a test track that had some constant bass line and it sounded better on the bookshelf. I with a frequency analyze I could determine that the frequency were 80hz.

 

So when I have two 18" right and left woofers. Those are a bit behind the MMG and the DSP time align them ao that the MMG and the woofers are playing from the same Place and arriving at the same time to your ears.

(In other words it is like having a 3 way and no issue with localization when they are more or less where the MMG is)

 

The second thing is that the 18" woofers plays up to 2000 Hz linearly.

 

So then I thought: why not let the 18" woofers play the 80 Hz instead of that the MMG is doing it.

 

So i made the crossover point at 100 Hz instead so the woofers play now the 80 Hz plus the Maggies would get some relief.

 

When I re-did the A/B listening tests now the bookshelves had not the upper hand any longer and the 80 Hz bass line in the song were produced by the woofers as good as that the bookshelves could!👍

 

Next thing I have done on my +40 year old MMGs that has the exact same plate/binding posts/fuse/attenuation connection.

I modified and put a good quality blinding posts. Plus scraped the fuse and attenuation steel components and went directly to the crossover.

To be honest I usually don't hear any difference when I do tweeks.. And I usually/sometimes let the tweek be in the system when I have not heard any degradation either.. but when no noticeable sonically improvement were the tweeks worth it.?!

But this time when all that crap steel connectors and all the solider joints, were removed from the signal path I heard a real improvement. And I were just baffled with the thought that nobody that are listening to their MMG/LRS in orginal condition have yet NEVER heard their full potential! 

(The silly signal path for the Tweeter on the MMG/LRS:

First bad steel binding post for your speaker wire, then solider a lead to that solider to the fuse holder then contact with the fuse and the little thinn fuse lead and another end of the fuse and its clip holder solider wire to the steel binding post for the jumper (attenuation) to the other steel binding post and the last soldier to the lead that now eventually can go to the crossover..) 🤣
