I would like to find a center channel speaker to hopefully boost dialog on movies.Current fronts are Paradigms MkII 7se's. Rears are Paradigm bookshelf-size speakers from the same era -the sticker fell off the back a few years ago - they are maybe mini mk II's? There is a velodyne V 1012B sub. Driven by a (frankly underwhelming, but that's for another day) Pioneer VSX-31.I know the speakers are old, but we like them and are not inclined to replace them. They have been treated well and, so far, the surrounds and individual speakers seem to be holding up. It's only the volume difference between dialog and background music/effects on movies that is a problem.I am hoping someone here can help identify a center speaker that would be a decent match for the 7se's. Ideally the price is something in the neighborhood of $200-$300. A discontinued/closeout model from previous years and/or something from a manufacturer other than Paradigm would be fine.Thanks for any help.
