Which ones don't you care for? The C444, or the 555/777.
Haven't heard the 555 or 777's yet, but they have the same waveguide horn as the C444, so I'd imagine they are the closest match.
I'm not sold on any of them yet, but budget is tight as hell.
(Read, I'm selling my Polk CS245I for $90. I can add $50 to that for a new center, that's all.)
I'll eventually replace the L/R as well with something to match, but that will be down the road a bit.
Wish I could spend more, but just spent the past 4 years rebuilding my house from scratch (i.e. new wiring, plumbing, drywall, roof, kitchen, bath, siding, etc, etc, etc.)
Now I have a beautiful house, and it's paid for in cash, but I'm broke as a joke! LOL!
Not trying to do new boxes on the cheap, but that's about where I'm at.
A buddy of mine has a Paradigm center that I tried out with the AM100's. The horn on the center was AWESOME. Bright and clear without being overbearing or harsh. Not sure what model is was, but it was considerably bigger than the Polk.
Thanks for the input!
