Right at about a month now and these are still holding their own, meaning, I have not tired of them or sought a better listening experience. I do notice them audibly opening up at about their halfway point. This must be where the dipole arrangement must start reacting more favorably with my room. By halfway, I mean from about nothing to where I pushed them initially finding where the enclosed driver started reaching audible low frequency distortion. Still, half of where I would dare to drive them is about my normal listening level at night, or around 75-80db with the sub. I have driven them for hours at higher levels and they don't mind.
If someone were to build these as a near field system with a responsive 8" subwoofer in a 12" sealed cube, they would be pretty tough to beat in that sort of 2.1 desktop class, if they were willing to let their audiophile guard down and just slum it for the sake of what amounts to some top notch, casual music listening. The fact that these perform as well as they do in a larger duty than that is telling to that effect.
