Thanks for the compliment, ninoe99, but the Maggie 1.6QR is simply not biampable without ripping out all the circuitry in it and voiding the warranty. Its big brother the 3.6QR can be biamped, but it's >$2500 more. Nice if you have the $$ and space, but I have neither. There are a lot of DIY upgrades for the 1.6QR at http://www.integracoustics.com/MUG/MUG/ and they all involve upgrading the crossover components or rebuiilding the whole crossover network, and/or putting external braces on the speakers. (I'd be interested in hearing one of these upgraded speakers - anybody know of any in southern California?) But none of the changes involve making the 1.6QR biampable.
