a couple of questions about maggies


i was wondering if the magnepan 12 speakers are set up for bi-amping (2 sets of posts per speaker)? would two b&k st-140 amps power these speakers well? i believe that amps are rated at 105wpc @8ohms, but magnepan says their speakers are 4ohms. if bi-amping is possible, then each speaker would get a total of 210 watts. is this too much? if biamping is not an option, then what amp would you recommend in the $500-$800 range? my room is 11'x14' carpeted with one side open to a balcony. thanks.

Two points of interest...

1. I am using CarverPro ZR1600 amps with MG1.6, and the result is superb. The available power, 600 wpc, is ridiculous, and I am sure it is something that "comes with" high power (current delivery perhaps) and not the power itself that really makes these speakers shine. At only $840 these amps are a steal.

2. I have just modified my MG1.6 crossovers, using a 10AWG air coil inductor, and Hovland capacitors. I expected only improved sonic quality, and was surprised that the sensitivity (dB per watt) increased significantly. This might make the MG1.6 more suitable for relatively low powered tube amps. (I did slightly change the crossover design, using 3.0 mH and 21 mfd instead of 3.5 mH and 22 mfd).
