Magnepan, How Low Can You Go...power-wise


Hi Guys,

I have used a pair of Maggie 1.6s with a little Naim Nait5i (50wpc) and they sounded ok. I hear a lot of people saying you really need 250wpc to make them sing. I have the opportunity to buy a pair of Maggie 3.6s very cheap in another country where I spend some months each year. I was hoping my Simaudio i7 at 150wpc would be enough power for these. Magnepan won't answer this question firmly - what do you think ?

Thomastrouble,

Again my personal feelings here tell me that both the Bel and Sim should do the job as they are quality amplification and I am assuming that the power ratings we are discussing are 8OHMS, power output should come close to double or actually be double at 4OHMS so you should be more than safe.

be careful underpowering the 3.6s. you're more likely to to damage the ribbon tweeter from underpowering (clipping) than overpowering them.
From what I've read, the tweeter will fry with the tweeter fuse still intact.
Well, the maple-wood guy claims his modified small tube integrated amp (30 wpc?) can drive the 3.6. Interestingly when I've seen Magnepans at shows, the company bi-amps them with large Brystons (600 wpc?). That should tell us something.

Of course the usual considerations apply; size and furnishings of room, type of music played, preferred listening levels, etc. But my experience in listening to any model Maggie is they all have a minimum playback level where they come alive. Below that and they sound limited, as if the several veils reviewers talk about are still in place. So to me the question is not what is the smallest amp that can play Maggies, but what is the smallest powered amp that can make them perform at their potential?
Thomastrouble, I can tell you from much experience, that yes you can run Maggies 3.6r's with lower power amps, but you will not hear what they can do with those amps. They will be veiled and limited with almost no bass or impact.

If you are really keying on the smaller powered amp, you could get a different speaker that would do more for you.

The Vandersteen 3a comes to mind in that price range. With lower power amps as you want to use, you will get much better, cleaner, more open sound from the Vandy's.

I would also look at the Paradigm Signature S6, a great speaker that can be found in the same price range.

Or look for some really nice monitors that are more efficient.

You will not get what you want from Magnepan 3.6R's with low powered amps. Sound will come out, but not anywhere near what they are capable of.
Thanks guys.

Macdadtexas, thanks for the input. I realize that to make the Maggie 3.6s sing you need good power. What I am getting at is what is the lowest power amp you could use but still get GOOD sound - would 150w at 8ohm from a good integrated (Simaudio i7) cut it? The Vandersteens have definitely interested me but I have the opportunity to buy the 3.6s very cheaply in a country where I spend some months each year. If I had the same opportunity to pick up the 3a Vandees at a good price I would, but that is not going to happen in Brazil. The 3.6s belong to an american in Sao Paulo who can't justify dragging them back to the US, so is letting them go very cheaply.
