I am in search of recommendations for good in-wall subwoofers.

To my dismay, my favorite Xmas present, an EP175, was resoundingly rejected by my wife (I'll spare you all the gory details of her reasoning). So now that the EP is packed up, bid farewell, and trudging begrudgingly back to Axiom, I need to find its brotherly, in-wall alter ego. I'm looking for similar specs (I'm shocked as to the limited range in some of the subs on the market), and hopefully not too much greater a price (though I fully expect to fight the battle for 'better looks is going to cost us'). I'm hoping some of you out there have specific experience with some of the subs on the market, especially given the migration towards 'invisible' speakers these days.

Thanks in advance for all your help! (and here's hoping that Ian and the crew can invent the next great in-wall system for Axiom...)
