For home theater application, you will be better off to use an AV processor with Audyssey room correction. They work much better than simple analog EQ. The one I like is the Marantz AV7005. I have set up a 5.1 system (AV7005 driving 5 Focal CMS50 and a CMS Sub) last year as Christmas gift for my mom. The result was nothing short of stunning.
If you really want to use analog EQ, One of the top brand is Soundcraftsmen. I have used its EQs many years ago. I don't think it is still in business but it is considered among the best and you can find them in used market for very reasonable price.
