Summary: In my Media Room I utilize the larger Energy AC-300 center channel speaker for all five channels. I've used them for over 10 years. In 2010 I saw these speakers at a very low price. I ended by buying 10 of them and set-up five for my master bed-room and put another 5 in my son-in-laws living room. They have been great little speakers. I recommend only using them as surrounds for large rooms. For small rooms you can use them on all five channels.
Summary: I bought these to finish my theater that already had other Energy Take SAT's in a 5.1 system. The theater now sports a 7.1 and these are exact matches to the others. This particular model is currently out of production, but the Energy label is nothing to sneeze at. My Energy system sounds wonderful and it replaced a $4,000.00 Dynaudio 5.1 system. My Dynaudio's were wonderful too and i really hated to let them go, but my wife hated the size of the speaker cabinets.
Summary: i've had these speakers for 2 months now.. sounded great.. no problems. a few days now, i have been hearing some high pitched rumbling (like white noise).. coming from the right speaker.. its really irritating. i thought maybe this happened because i was using them as front speakers? but that shouldnt even be an issue for such expensive speakers.
Summary: I've had 4 of these speakers hooked up to an Acoustic Research center channel and subwoofer as a complete 5.1 system. These speakers have very nice and clear sounds. In the past, I've had the Bose, Acoustic Research, and Klipsch Quintet III 5.1 systems, and these Energy Takes actually produce the best sound quality out of all of them. For some reason, I'd like to replace speakers once every 3 years or so to sample their sounds, as some do it with cars.
Summary: I've used this speaker both as and addition to a Take Classic system (as the front channel speakers in a 7.1 surround system) and as surround speakers in a higher end system (Two Take TWRs for the front channels, a Take FPS for the center channel, and four Take SATs for the surrounds. These speakers have a nice, neutral frequency resoponse that make them a great home theater speaker.
