Does anyone happen to know the impedance range of the lsi 9? In particular, what are its characteristics around 60Hz?

Lsi9-
87.3db. sensitivity,
4ohms nominal, but can reach down to around 2.5ohms at 200hz and 52hz (where the powerport kicks in).

Lsi7-
88db. sensitivity,
6ohms nominal, but can reach down to around 4.2ohms around 212hz and 54hz (where the powerport kicks in).

hope this helps. Polk's own measurements for these speakers are not quite accurate.

OK, thanks. I hate to ask, but what about the lsic?

there is no specific 3rd party info on the lsic- so just go with what Polk says. 4ohms nominal across the board, 88db sensitivity.

If you go to soundstageav.com there is a link for loudspeaker measurements. They did a series of tests/measurements on a bunch of speakers including the LSi9. Unfortunately there is no info on the LSiC. Hopefully this info helps.
