Magnepan Owners - Need Your Thoughts Please

Spent some time recently auditioning the Magenpan 12's and 1.6's; I was very impressed with the sound, especially when you consider their modest cost.

I've always had highly sensitive horn speakers so a Magnepan is a totally new direction for me. I will keep my Khorns and consider adding the Magnepans for even more fun! Here are some questions that I need help with. Of course, I will bring them home for a personal in-house listen before I buy but any thoughts that you Maggie owners could add will be greatly appreciated! Questions:

(1)Will a pair of 125 watt VTL monoblocks (EL-34's) be enough juice to drive the Magnepans to reasonable listening levels in my large room (17.5w x 26L x 9h). By reasonable levels I mean 85db - 90db (at the most). I don't want to 'blow-up' the VTL's! They are rated at 130 watts in Tetrode mode into 4 ohms.

(2)I assume that the larger panels of the 1.6's would be harder to drive overall than the smaller 12's?

(3) Setup advice: where do I start on placement? How far from the front wall and how far from the sidewalls? How far apart? Also, are Magnepans designed to be faced straight-ahead or with some toe-in? And, what about the ribbons, placed on the outside or inside?

(4) What are the appropriate listening distances? How far do you sit back from the panels?

Would love to hear Magnepan owners' comments and advice on these questions or any other Maggie issues that I am not thinking about. Thanks!

Well, Stickman, are you ready to try a few tests?

Turn 'em around. Yep....put the mylar to the wall and the pole piece facing you, the listener. Magnepan flipped sides maybe.....15 years ago. I didn't get the memo, so when I went from MG-1 (late '70s vintage) to the 1.6 it took me a while and lots of reading to realize the cause of one of the largest differences between those 2 named panels.
Don't forget there are FOUR (4) ways to orient your panels. Mylar front / back and-or tweeters in/ out.

ALSO, get out the tape. I measure my panels distance to the wall. I use the edge of the tri strip as my reference. I am at 30 1/2" inside and 34" outside.
This is just over a 10degree toe and crosses the speakers about 20 feet away, well in back of me.

To get louder, don't forget relationship between additional power and loudness. Even going to 250 a side, you may not get loud enough.

Dsper? One of the few I've read who use Magnepan with Mac. I'd like to hear such a setup. For me in my room, the MA6900 or MA7000 would be about right.

Magfan,

I always wanted a McIntosh amp since I was in college and finally got the extra coin together to afford one when I turned 57.

I have not listened to anything else with the Maggies and do not know how they might sound with something else.

I think that the Mac quality is there and the protection cicuits work. Before the Maggies, I listened to double stacked Large Advents. While moving the stacks around I managed to cross a wire and the amp protected itself and did not "blow up".

With either the Advents or the Maggies, the amp is dead quiet when it is supposed to be.

Hi All: Does anyone have experience or an opinion regarding how well an Audio Research Corp VS-115 will drive Magnepans? I believe the ARC VS-115 generates 135 watts power into 8 ohms; 125 watts into 4 ohms.

Hi Bifwynne,

I posted earlier and made a positive comment about my Mac amp at 160 wpc into 8 ohms and Maggie 1.2's.

Since that time, I had the opportunity for an in home listen with a Krell s300i at 300 wpc into 4 ohms. The difference is amazing.

Much more detail and separation of instuments with the Krell. On occasion, the sound seemed to be emanating from outside the speakers.

I initially thought that the Krell sounded too bright but after a week of listening I no longer feel that way.

I now agree that Maggies need a lot of 4 ohm power and suspect that I am going to have to make an amp change.

Bifwynne, J Valin used a ARC VS-115 to drive 1.7's.
