Hi to all,
I read opinions about Aksa amplifyers with great interest. Due my engaging in music and HIFI gear over thirty years, some statements comes to my mind and one greatest and most important of them is- trust your ears only. What mostly wake up my attention here, was many unbiaset reports from happy owners or yet better, very pleased Aksa owners. The time passed by and many money too, due tests in various newspapers and magazines, so the time is mellow now for proper decision. My question here is, would  100 watts be enough to drive Magneplanar 1.6Qr ? I listen all sorts of music with normal listening levels? Thanks and regards to all
Rusty

That is not so hard a question to answer yourself?
You know the specs of your maggies, don't you
you know that Maggies are a very very stable load for amps, so 4 ohm is 3.6 or higher
sensitivit 85, 86 db per watt.
So add 3 db for 2 watts
2 watts 89 db
4 watts 92 db
8 watts 95 db
16 watt 98 db
32 watt 101 db
64 watt 104 db

so 55 watt will be around 102 to 103 db (very loud!!)

and 100 watts will give you close to 106 db.
This is not for peak
peak values  of the AKSA's is 3db (I suppose) more than the rated power
and their rated pwr is for 8 ohms.
SO 100 watts will be 200 watts musical power and more than enough for yr Maggies

Hi Rusty,

Thank you for your post, and welcome to the forum!

Yes, the AKSA will drive Maggies beautifully, and in fact AndyR has Maggies with triamped AKSAs and may be able to advise you further.

I have seen and heard Andy's system, and it is most impressive.  I'll leave it at that;  let us see what he says!

Cheers,

Hugh

Hi to all, ... would 100 watts be enough to drive Magneplanar 1.6Qr ?...

Rusty, I think Kyrill has given you your answer but here's my A$2 worth (that's 2c US!!   ).

As Hugh says, I tri-amp my IIIas.  As far as I am concerned, 100w is plenty for the base drivers but I have corresponded with people who say they need 500 w/ch for their active Maggies (and who wonder how I can "live with" a measly 100 watts!).  Of course, a 100w AKSA has a power supply which can deliver a large amount of current so perhaps it really can be classed against other "commercial" amps whose marketing departments claim they are "500 watters"!!??

I'd be surprised if an AKSA 100N+ (better base!) couldn't make your 1.6s sound fantastic!  If you then get hooked and want more you bi-amp them - either passively or better, in my opinion, actively.  I don't know if you know of the Mauggie User group (MUG) on AA but you'll get plenty of help there.

Regards,

Andy

Hi Rusty,
I beleived that there are AKSA owner close by in Zagreb I don't know him personally but I know  some friends in Bosnia, its a too far I think for an audition but at least for you to be aware of.

Hi to all,
I am very impressed about your knowledge, where Slovenia is. Zagreb is app. two hours away from me. Another question for Mr. Hugh! Is there possibility to start test rundup with Aksa through EU? Here are enough interested people for test! I believe, due do it yourself price is Aksa very interesting object, reading all satisfied custommers, there must be sonic precedence too.  Another question, I have my personal business, would be of your interest to sell  products in Slovenia?
With respect,
Best regards

One more good thing about the Maggies is they are something of a line array or line source which will maintain its SPL at greater distances than point-source speakers.  

Basically any regular speaker will lose about 6dB with every doubling of distance from the speaker.  Line arrays only lose 3dB with every doubling of distance (now somone please speak up if I have this wrong cuz I can't quite remember if that is right what I said but i know there is some truth there).

This again translates into more SPL than your average speaker at your listening chair so less power is required than you might anticipate.


On a side note regarding 1.6's Crossover (slightly off topic)  I would get rid of the stock internal speaker crossover and build yourself two of those AKSA amps and a pair of passive line level crossovers.  This will open your 1.6's up to new levels most ppl never knew the 1.6's had in them.  Plus your amps will be dedicated to only a certain part of the frequency since they will each be crossed over.  

The best part of this will be the ultimate intimacy in the midrange, highs will be more crystal clear and airy and the bass will seem to be deeper and more powerful.  

I performed this mod on my 1.6's and it was the very best thing you cando for them.  yes you have to buy another amp but if you go the route of upgrading the stock speaker level crossover with all the works, you will still spend $350 roughly...so you might as well really do the right thing with 1.6's and truly biamp them with two amps a simple PLLC.

Anyway, this got off topic so I apologize.

Hi heavystarch,
Thats it!!! That was direktion, I am thinking off. Yes, I  agree with you in all  points.  Qestion, would be two of Aksa amps enough for biamping? Could you send me a shematic of that please, and shematic of passive crossover plate with needed parts? I am quite good with soldering gun, so that is ok. Crossover plate,  have you still dimensions of her and perhaps, where could I buy two with parts? See, you helped me and now so many questions' LOL
But  I am realy excited about all that, onesmore many many thanks for all that man.
Best regard for you

Hi Rusty,

Thank you for your posts.  Are you in Ljubljana? (spelling might be wrong).  I seem to remember a doctor friend telling me of the very sophisticated hospital system you had in your capital as far back as thirty years ago;  he spoke very highly of your cities and your health institutions.

I do have an AKSA owner in Zagreb, his family name is Simunovic.  Zeljko, are you there?  I will PM you with his email.  And I've just sent an AKSA 55W to Dejan Veselinovic in Belgrade, too.

To be honest, if I were driving Maggies, I would choose the 100W AKSA because of the lowish sensitivity and the need for reasonable headroom since Maggies are often driven hard.  Have you reglued your voice coils yet?  

Yes, I too am thinking about marketing, but if I had an audition amp in Europe it would most likely be based in Copenhagen with Jens Thorsen, AKSA Scandinavia.  We talk of these things quite a lot!!

Cheers,

Hugh

Hi Hugh,
Thank you for answer. I am living in Slovenj Gradec, thats 120 km nord-east of Ljubljana, 10 km from Austrian border. Small town with 30.000  inhabitants, surounded with high mountains, nice for winter sports and sommer activities. Yes, I have small company, but at the moment, doing nothing with it, just searching for appropriate product. Have great love for Hi fi gear, and a little experience in such things too( that comes with years and many wrong purchasing, but that is something  we doing all?) Yes, our hospital system is very well known and  well grown, but in recent time something different from old one, we have now another system, former was socialistic and now capitalist one as you have, thats mean, if you have enough money, you have also first class medical care, but that is another theme. Generally is not so bad and we live decent  existence. I am looking forward  your development of complete kits,  as complet with all needed parts, such as case, knobs, all together in one place, that will fit seamlessly to build all together in one part. Please, keep me informed of progress in that case.
I have contact also with Greg Osborn from Australia, from your country are many well known wonderfull people and due Internet we are all together now.
Best regards Hugh!
