i just gave the LSi15 a listen the other day, and two words immediately came to mind: holy s h i t!
i've always poo-poo'd polk as a Best Buy speaker whore, but after the LSi, i'm chowing on a plate of crow.
they were set up at a HiFi Buys/Tweeter, in the same room as the JMLab/Focal Cobalt 816. quite simply, the Polks did everything better. it wasn't even close... the Cobalts were totally put to shame.
if i'd had the money, and if Tweeter had any interest in/knowledge of/merchandise for 2-channel audio, i would have bought them on the spot. they had pretty much everything that i'm looking for in a speaker.
i mostly hear raves about the smooth, articulate highs from the vifa tweeter, which is certainly true... but what really sold me was the tight, musical and completely unbloated bass.
i wish i could've heard them against some B&W 7 or 800 series. i think they'd compete quite favorably.
they were quite pretty as well, with the possible exception of the grills.
