Fairly good price on the 520C center that matches with other Studio 5 series speakers (580, 590, 530). It has been as low as $180 in the past, but not for a while.
This has the same compression driver tweeter as the other Studio 5 series and sounds outstanding. If you have Studio 5 series fronts, the is THE center channel to get. I initially bought the Studio 235C and returned it after hearing the difference the 520C made.
