Picked up a Polk R400 to try it out after all the hype about the Reserve series and its trickle-down tech from the Legend series. Have to say it is disappointing: lows are boomy instead of deep (despite the size and weight of the speaker, as well as its rear ports), mid-range is so-so (probably due to a 2-way design), highs are downright poor (so much for the pinnacle ring radiator tweeter), and horizontal dispersion at 20-30 degrees off-axis sucks (probably due to the MTM design). Going through a 2-hour show with plenty of dialog and few surround effects is simply unpleasant for others in the room as well. Back to the store it goes.
