Sitting here in my living room listening to a pair of these and a Speedwoofer 10s MK2 absolutely stunning me while playing Puscifer (and everything else I throw at them). I'm not sure you could do better for a 2.1 stereo setup without spending at least $2k, rather than the $750 this system cost me. The soundstage, clarity of vocals, and the seamless interaction between speakers and subwoofers are all too notch.

And as the LCR in my 5.1.4 system, they're equally fantastic. Dialog is crystal clear.

Two caveats: (1) I'm coming from a non EQ'd Sonos Arc and Sub (thanks Sonos, for not supporting Android); and (2) I'm driving this system with the Onkyo TX-NR7100 and have Dirac Live room correction applied. Dirac is doing a *ton* in my completely ridiculous "theater" I've carved out of an 18x20 "great room". Still, Dirac can't do anything other than make the speakers sound "as intended," so I promise that if you're unsatisfied with these speakers, either you got a defective speaker, or your speaker placement/room configuration is ruining them.

Makes me curious about how the 5 series sounds...
