These seem like really impressive speakers, that actually do contain some well thought out novel features that advance the art from the norm. This has been achieved without absurd impedance and phase angles. The world continues to be awash in expensive so called 'high end' speakers, that when you really get down to it are not very good. I agree these speakers are a bargain.\n\nI think these speakers would handle the LFE channel. So with a pre pro and a couple of power amps, you could use both the line outs and the balanced XLRs and mix in the LFE output to the bass section. This is what I do. I firmly believe in an integrated full range speaker system that does not need spaced subs. Having had the experience of this approach for 15 years now, I do believe that is optimal.\n\nThe fact that speech was very good without a center, attests to the fact that these are very good speakers. There would be few, if any centers on the market currently that would not detract from these speakers. \n\nThere really is a place for good truly full range speakers in the HT environment.\n\nBut! Besides the fact that you can simply use three of them to have a perfect center, they also offer a horizontally aligned center that is basically this speaker on it's side with the waveguide turned. It measures equally well and has identical timbre and dynamic range. So they do make a center that perfectly matches the speaker. Center channel speakers rarely measure all that well and don't typically match the L-R speakers. This one really does.
