Sony Soundbar | HTRT3.CEK is rated 3.5 out of 5 by 25.
Rated 2 out of 5 by from Good sound at the price but............ I bought this home threatre system on 3 January to go with a bravia TV being delivered the following week. Within two days I became aware of the fan noise coming from the sub woofer that is the power base for the rest of the sytem. The fan noise goes up and down when thyere is or isn't noise in a programme. This is most obvious during programmes that just have talking and at volumes below 21 on the system. During action movies this isn't noticeable. I have never heard noise from a fan in any previous system.

Rated 1 out of 5 by from Unacceptably noisy cooling fan in the sub-woofer. After extensive research and a wait of a month for its release I purchased the HT-RT3 soundbar. From the audio quality, ease of set-up and aesthetics I would score it highly. However, there is an audible, distracting and unacceptable noise from the cooling fan located in the sub-woofer. This is most evident when there is a lull in TV audio output and the fan can be clearly heard to reduce speed with a whining noise.

Rated 1 out of 5 by from Very loud fan Great sound but unfortunately ruined by the annoying loud fan on the subject woofer... exchanged the first one after a week...only to find the new one has exactly the same annoying fan.

Rated 1 out of 5 by from Not at all happy with this product Purchased three months ago and the sub woofer's fan is proving to be very noisy. Even to the point of distraction.

Rated 4 out of 5 by from Does what it says Works well and delivers good sound. Others have mention the amount of noise from the cooling fan and although this is sometime audible in general it's not a problem. Connected to my TV using the HDMI (ARC) which means it comes on with the TV - nice that you don't have to manually switched on separately, although I have had some issues with this but I can't tel if it's the TV's fault (not a Sony TV) or the sound bar. There are other sound bars the deliver more features but for the price I think this is a good buy.

Rated 4 out of 5 by from Great sounds Great item sound is fantastic, and easy set up. Placement is difficult with original stand as it has to fit in front of tv which blocks sensor for remote. An aftermarket stand took care of this but at an extra expense a little more thought in the design of tv stand would do away with this issue

Rated 1 out of 5 by from It has known problems - I should reseached more Disappointed with this sound bar. I bought it at the same time as a Sony 55 TV. The sound is out of sync and the fan is very noisy. After doing research it looks like this is a common problem with this sound bar. Someone has posted a temp fix for the sync problem (go into menu and toggle sound effect off and on) but you need to do this everything you turn the system on. You get used to the noise of the fan but the problem is it speeds up and down so sometimes you hear it and other times you don't. The Sony TV is fantastic. It’s a real shame that the Sony sound bar is so poor. I think the issues could be fixed by a software update but as yet Sony are not recognising this problem.
