Thanks Nick! You guys have me chuckling about the size of these speakers. I still have my big old six-stacked-cabinet speakers in our listening room, because we don't have any place else to put them (anyone want to buy them?). The Jägers seem almost lost in that room by comparison. We also have Jägers in our 10 x 14 home theater and they are working really well.
Using two Kaijus works really well, more of a good thing. But I don't imagine you need them in your room. Right now in our fairly big, well treated room I am biamping, using monoblock Kaijus on the tweeters and our prototype Big Betty 50W parallel SE 6550 amps on the woofers. And a Neothoriator as preamp. Aaron Johnson is one of my sets of critical ears, and he seems to approve of the current setup. It can get really loud.
