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.

Maggie MG1.6 come with 1 ohm resistors (attenuators). The instructions say that the speakers are flat without the resistors, but, because many recordings are equalized with a "hot" high end to compensate for rolled off speakers, it may be desirable to use the resistors. I am not familiar with other Magneplanar crossovers, but in the MG1.6 there is no tweeter padding resistor in the crossover. Most speaker crossovers have tweeter padding resistors in the range of 1 to 3 ohms, so the Maggie attenuators are just tweeter padding resistors, of lower-than-usual value. And, you get to pick the value you like.
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.
