Magnepan 2.7QR owners...please.


A few months back, I purchased a used pair of Magnepan 2.7 speakers for my son's system. Although he is quite happy, he asked some questions I can't answer and seek your help.

What do "Tweeter attenuator" and "Midrange attenuator" mean?
Are the extra speaker inputs for biwiring or are they supposed to just fit the small "U"-shaped metal bars that came with the speaker?
Are there any outboard crossovers available for this model?
For my taste, these speakers are a tad bright although they are remarkably transparent. Can some of this brightness be modified?

Thank you very much for your consideration.

Jafox, where would I purchase these 10w resistors and how are they attatched to the posts?

Thank you for your time.
Vvrinc: Radio Shack sells 1-ohm 10w resistors. They are a dollar or so each. What I suggest you do is buy 4 of these. This would allow you to use 2 per side to try out 0.5, 1 and 2 ohms to find a value that gets the level to your liking. Once you find the value you like, you can find a higher quality "audiograde" resistor to replace the RS parts. There are many online sites that cater to DIY audio hobbyists with high-grade electronic components.

These power resistors have relatively thick leads. You can bend the ends 2 or 3 times and put these directly in the socket currently being occupied by the metal jumpers. There's no need to solder the resistors to banana or other connectors first.

Hope this helps.

John,
Many thanks for your guidance. Will post results in a few days. Also thanks to the other members that have helped clarify the terminology.

Best regards,

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.
