Magnepan 20R vs 20.1Rs

Bbro,

The only difference physically between a 20R and a 20.1R is that there is magnets both in the front and in back of the bass and midrange panels on a 20.1R and only magnets front/back on the bass panel on a 20R.

I have spent much time comparing the two speakers and can honestly say if there is a difference between the two speakers sonics it is very slight. Maybe, at very high volume the 20.1R's might hang together a little bit better, but I never play my system that loud anyways.

That's way I never upgraded from the 20R's when I had the chance years ago. In my opinion,both speakers only perform at a magical level when you use an active x-over, biamp, and put them on MyeSound stands. Hope this helps.

'only'?
The difference between push/pull Maggie drivers and 'the rest' is substantial.

The pole piece is a substantial part of the speaker. As a matter of fact, i rotate my panels to pole piece TO the listener. Magnepan all were this way until sometime in the 90's when, for some reason, they swapped sides.

My original MG-1s, which I had for 20+ years, were pole piece to the listener by design.

Magfan,
I am not quite sure what you mean by "pole piece"? And what do you mean by rotating the panels TO pole piece to the listener? Sorry if I am dense.

Thanks.
