I'm by no stretch of the imagination an Audiophile, but will do my best to give my impression. When I started my quest for a HT system, I was headed to the local big box for a Bose surround system. I've been a member of a football forum for years, and there is a great diversity of interests there, so I posted a question for opinions on Bose. Some were positive and others, not so much. So I went out and started listening to speakers. JBL, Klipsch, Def. Tech., Etc. Etc. Etc. Bose was eliminated right away. Not a bad sound but I could definately tell the difference when compared to nicer speakers. I was very impressied with Monitor Audio. Small satelites with a fantastic range and sound. Due to their expense I figured I'd just piece it together over time. Not really knowing anything about the brand, I posted another question and one of the replies pointed me here. After reading about and researching, and with the 30 day trial considered, I figured I'd go for it. So I ordered 2 4T's, a 4C and an 8D.
When I first hooked them up, I wasn't immediately blown away as I expected to be. They sounded good and put out a lot of volume for such small towers, but seemed tight and stuffy, Given the documented need for break in, I wasn't too concerned. Well, I can tell you know, once these things break in the difference is significant. The sound stage has widened considerably, and they sound very light and free. The 8D is phenominal and is everything I wanted in a sub. Very tight and defined bass with the ability to rattle the windows in my 15x18 living room. I can't say enough for how good these speakers sound. And, after listening too many different speakers, I'm confident you won't find any that sound this good without spending several times the price. I'm running wire for side surrounds today, and will be ordering a set of 4B's to complete my system.
I might consider upgrading the 4C to a 5C when I build my new entertainment center. Given the importance of the center channel, and thiniking it will match well with the 4T's, I might make that change.
