Summary: I bought the c25 to be the center between two infinity Primus 360s. Based on the product reviews already out there, I felt comfortable buying this product, and my experience certainly matches the general consensus that, for the money, this is an excellent speaker. The dB rating is lower than some of the other speakers in my setup, it seems very crisp clear and pleasantly loud for the movies I watch.
Summary: There were several center speakers to choose from, and within my price range, they all looked good. The one I first chose was undeliverable, so I chose this slightly more expensive INFINITY model. It turned out to be a case of Fortuna, goddess of chance, giving me a break, for a change. Fast delivery. Perfect condition on arrival. Easy hook-up, and flashy first demonstration.
Summary: I just purchsed this speaker as part of the PRIMUSHCSCH Home Theater Pack of speakers (I'm pretty sure it's the same one, it has the same type drivers and configuration but drivers are 4"). Look at (professional) reviews of the Infinity Primus speakers and you'll see these speakers were created for musicality first, although home theater sounds great, too. I first and foremost want a system that sounds tight and clear playing at all registers.
Summary: I have been looking at buying a center channel speaker for my set up and I have found it. It is very clear but not to bright. It reproduces voices really good. I compaired it to the Kilipse that are also in this range and polk cs 2. Thi sone sounded the best to me. I was able to get mine for $120 so shop around. But do go to a store and bring a cd that you like and listen to it with your other speaks if they have them and you will see what i mean.
