magnepan experimenting

I rotated my 1.6s a few months ago when I realized that Magnepan had flipped 'em around in the mid-90s. My original MG-1s were mylar back and I liked 'em lots....even though they were something like.....50hz to 18khz. no better.

When I did the rotate, I noted MUCH better imaging and ended up with the toe adjusted to cross well behind me. The sweet spot opened up and now every seat on the sofa sounds fine. I had to flip the phase switch on the Sub, too, which confirms my new placement.

Tipped up response or not, the brightness I noted when the mylar was to the listener and the toe was set for a proper image is GONE. They were more beamy and with a smaller sweet spot. Toe adjusted out would help, but eventually produce a 'hole in the center' effect. Toe adjusted too far 'in' would make an image about 5' wide with ZERO extension past the speakers.

Hotmailjbc.....did you EVER try toe adjusts? or Flipping 'em front/back? I think toe is ESSENTIAL to help disperse the strong backwave.....from the nearest reflecting surface.

I'm leaving them pole piece to the listener, but may do a L/R swap and again try the tweeter 'out', but this time listening to the 'wrong' side.

Try it, You'll like it.

Those measurements were made on the MMG's, anyway, so despite their similarity to the 1.6's I don't think you'd necessarily get the same tipped-up (then rolled off above 15k) highs.

As you imply, you really have to try them every which way, to see what works best in your room.

Any rectangular room is a candidate for focal point speaker placement. This costs nothing to try. I tried it with my Acoustat speakers with very good results. If you have the room to move the speakers around I think its worth trying.

Another member posted the information on it.

Hotmailjbc,

Interesting, I think I'll give it a try and see what happens.

i,ve turned my mags around so the mylar faces the wall and they work great that way. still experimenting with toe in and placement
