Magnepan 2.7QR owners...please.

I didn't see anyone mention, you can NOT bi amp 2.7's. I don't know why, but the dealer asked the maggie rep and he said they could not be bi amped.

Mab: There are a lot of DIY Maggie owners out there who have bypassed fuses and attentuator connections, replaced internal crossover components, rebuilt external crossover boxes, etc. I am sure that with a little effort, anyone could configure the 2.7's to be biamped. It would just void any remaining warranty.

Mab2112, I now understand that they can not be biamped or biwired. However, John's suggestion to use resistors has made an enormous difference in the sound of these speakers. Today we started using 2 Radio Shack 1-ohm/10W resistors per side and my son and I agree that the top end is much more natural. Before, the sound sometimes was eardrum-splitting with many recordings. With the resistors, there is no apparent compromise in sound but all frequencies are much more balanced.

We ordered better (?) resistors from an online company to replace the Radio Shacks eventually. If all 2.7s suffer from this exaggerated top end (that is, unless you like the feel of blood running down your temples), this solves the problem quite nicely.

Thanks to all once again and best regards,
Santiago

As a longtime 2.7 owner a few suggestions:

1) Try using short pieces of wire instead of the metal bars. The metal bars sound horrible. I found cardas wire to work well for the jumpers.

2) If you use resistors, get some good quality ones. I tried both the cheap resistors and some high quality resistors and they sounded much better (less conjested).

3) Cables make a big difference. I found Wireworlds worked really well with my 2.7's.

4) Get a big amp. Not sort of big, really big. 500w/ch into 4 ohms is just where these speakers start to get happy.
