How do I improve the sound on my TV?


Modern TVs sound rubbish.
We're happy to be up-front about this & if asked, most TV manufacturers would probably agree. There simply is no space for a decent set of speakers inside today's TVs, they are too thin and have very little frame to accommodate them. To make matters worse it's our own fault. The buying public, have over the last few years, swayed towards the most compact frames & thinnest sets available. This is therefore the trend the manufacturers have followed, resulting in worse & worse sound quality.
Click here to find in out more detail why new TVs have poor sound.


Getting better sound for your viewing experience is a relatively easy upgrade & there are various ways you can achieve it. Some options will run into thousands of pounds while others could only be a tenner.
A SoundBar could be the ideal
 solution for your audio woes.

The most common options include:
  • A full HiFi separates Home-Cinema system (5.1 or upwards)
  • An all-in-one Home-Cinema system (5.1)
  • An all-in-one Home-Cinema system (2.1)
  • A SoundBar, 2.1 audio system or Pedestal
  • Using existing HiFi equipment
The big question is which option suits your needs best?



HiFi separates Home-Cinema system (5.1 or upwards)
A HiFi separates Home-Cinema system is the premium solution for your TVs sound quality problem. Available from various different manufacturers and in a massive range of prices, these systems can provide stunning sound quality with huge amounts of volume, making them ideal for the larger listening area or for those wanting the best sound quality. Options available on this type of set up include up to & over 9.1 surround sound (nine speakers around the room plus one sub-woofer) with 200 watts of power per speaker.  As the items that make up these systems are made by HiFi manufacturers you also have the benefit of being able to play music at high quality too. This could mean that instead of having a Hifi & a Home-Cinema, you'd listen to everything through just the Home-Cinema.
This type of system does, however, have downsides, these being the level of complexity it will add to your system, the choices you need to make when buying it & the amount of room they generally take up.

For a full HiFi separates Home-Cinema system you'll need at least these 3 items.

A HiFi separates Home-Cinema consists of your choice of speakers, your choice of AV receiver/amplifier & normally your choice Blu-ray player (your existing Blu-ray or DVD will connect in if you want to continue using it). Because of these choices, this type of system has become less common in the average living room but still offers the best sound. A system like this will probably start from a minimum of £700 for reasonably good quality brands but can easily run in to thousands. Even from our range, which does not reach the very top end, we can supply just the receiver/amplifiers for over £2000. The flexibility in being able to mix-&-match different makes with each other is often very appealing because it allows you to get exactly what you want without compromise.
Another advantage of buying separates is that you are also able to change components as & when you want or need to. This means that if your Blu-ray stops working you can simply replace it & carry on using the rest of the system as normal. We have customers using the amplifier & speakers that were supplied over ten years ago with their brand new HD TV & Blu-ray player. The amp' may not be bang up-to-date but still provides great quality surround sound.


All-in-One Home-Cinema systems (5.1)
All-in-One Home-Cinema systems have been the most popular way for people to improve there sound quality for the last eight or nine years. Coming in at significantly lower prices than the HiFi separates & with less choice to make, they have found their way into many people living rooms. The reason they have been so popular is that they are easy to use, easy to setup and generally quite compact. They also have everything built-in to one unit. Blu-ray, DVD, CD, radio, iPod connections, amplifier & now Smart TV with music & video streaming services can all be included. This reduces the clutter, cabling & number of remote controls that seem to fill the modern living room.

All-in-One home cinema systems come with various speaker styles to match your needs & home decoration.
All-in-One 5.1 systems tend to come with a variety of different speaker sizes & although not with the same size of selection as HiFi separates, their should be an option suitable for your room.
  • Option 1 uses five very small speakers (the size of soup tins or smaller), paired with a small-ish sub-woofer. This is great if you need to place the speakers in awkward places or need them to be as discreet as possible. These tend to be the lower end of the all-in-one systems & are great for the smaller living room. The sound will still be much better than your TV's but you won't be able to drive them as hard as the more expensive options.
  • Option 2 generally offers more bass and more power allowing you to drive the system a little harder & really get into the explosions or car chases in your favorite action movie. This option will most likely also play your music back at a higher quality too. Because the speakers are slightly larger, positioning them may be slightly more tricky.
  • Option 3 will normally be very similar in performance to option 2 but has a very different impact on the positioning of the speakers. These are designed to sit on the floor & are quite large speakers to find space for. If you struggle for floor space or have children or pets, you may find they get knocked over or damaged because of their placement.

Despite their popularity, All-in-One kits do have their downsides.
  • Firstly, the sound quality tends to be fine for watching TV or films, but you are likely to find that music will feel a bit flat & like there's something missing that you can't quite put your finger on. If you're a fan of music, this might mean having to have a HiFi to play music on too.
  • Secondly, you can't upgrade them. For example, a few years ago Blu-ray was launched giving people access to HD movies. If you had an All-in-One system you needed to replace it all to be able to watch these discs. A couple of years later 3D Blu-ray came out & people had to change again.
  • Thirdly, but tied in to the above, faults are an issue. If the Blu-ray player stops working, you lose the whole kit while it's being repaired. If it can't be repaired you have to replace the whole thing.
As the price on these systems is significantly lower than HiFi separates many people accept that they might need to change them more often to keep them up-to-date.

Apart from the speakers, All-in-One Home Cinema systems take up very little space under your TV.


An all-in-one Home-Cinema system (2.1)
An all-in-one Home-Cinema system (2.1) works along exactly the same principles as it 5.1 sibling. The big difference here is that they are aimed at people that don't have room for 5.1 or people that simply don't want speakers all around the room. As desire for anyone purchasing this type of machine seems to be to minimise clutter, these systems generally have only the small-mid sized speakers. Quite often we see the speakers being placed next to the main unit on the stand under the TV. This wont give you the best stereo effect but will boost the sound quality significantly.

A 2.1 Home-Cinema system fantastic for the smaller room or to keep clutter to a minimum.

A SoundBar, 2.1 audio system or Pedestal
A SoundBar or 2.1 audio system is a very simple way to get better sound quality from your TV. These items are purely an audio booster. They don't play DVD or Blu-ray, don't have an iPod dock or radio, in fact they have nothing built-in at all. They plug directly in to your TV and let the sound (for whatever is being displayed on the screen) come through their speakers, giving you a much more impressive sound.

A SoundBar  is a horizontal speaker that sits either in-front of your TV on the TV stand or hangs on the wall underneath your TV. They come in a couple of different sizes to compliment the variety of different TV screen sizes that are available.

A 2.1 system is just 2 small speakers & a sub-woofer connected to the TV in the same way as a SoundBar. 
Some SoundBars are multi-purpose and will split in the middle to form a 2.1 system. This give you a bit more flexibility in positioning your speakers in the room.

The picture on the right shows a Panasonic SCHTB550 in both SoundBar & 2.1 layouts.




A Pedestal design is something relatively new to market & sits directly underneath your TV, on top of your TV stand. The only one we have seen so far is the Bose Solo. This type of design is probably the most compact of all the options.

With the Bose Solo there is no sub-woofer, which means even less cabling, nor do you have to find space to put speakers. Instead the Solo sits in the same footprint as your TV & raises it by approximately 70mm (3") but for most people this should create no problem at all.

The sound quality is big jump compared your TV but bay not be as heavy on the bass when compared to a 2.1 or SoundBar system.


Using existing HiFi equipment
This is possibly the quickest and easiest way to improve your TVs sound & is something I've been doing at home for years. Most decent TVs have had audio outputs hidden away somewhere on the rear or side panels. Historically they have been red & white RCA (phono) connectors and have "Audio out", "Line out" or an audio out symbol, most HiFi's have corresponding "Aux in", "Audio in" or "Line in" sockets of the same design. If you connect these together using a stereo RCA (phono) cable you can use you HiFi to handle the sound from your TV. Ideally you should have a speaker either side of your TV, but many people are happy just to have better sound, regardless of the speaker positions.

The stereo RCA (Phono) connections and the cable that plugs into (left) and the newer Digital Optical Audio output socket & associated cable that is found on most new TVs (right)
Some newer TVs may no longer have the RCA (Phono) connections. If this is the case, the chances are your TV will have a Digital Optical Audio output instead. This does the same job, but with a higher quality digital signal capable of transferring stereo & 5.1 surround sound. Your HiFi would also need to have a Digital Audio input for this type of connection.

Why don't new TVs sound very good?



TVs have probably changed more in the last 15 years than at any time since 1967 when colour transmissions started on BBC2. In this relatively short period of time we have seen huge improvements in almost all aspects of using a TV. These advances include the following :
  • Square (4:3) shaped screens have changed to widescreen (16:9).
  • Inefficient analogue signals have given way to the new digital ones.
  • We had seen the introduction of HD broadcasting.
  • Ceefax & Teletext have been replaced by interactive services such as BBCi
  • We can now use our TVs to watch iPlayer or other on demand services instead of recording.
  • TV's can now let you access Skype, twitter or Facebook as social networking gets ever popular.
  • Trudging to the rental store has all but gone as we stream movies via broadband instead. 
  • 32" screen sizes are now considered small. 15 years ago, 36" was as big as you could get.
  • TVs in bedrooms for children was still considered a luxury instead of a standard fitting.
  • Mounting a TV on the wall was a feet of structural engineering and only really happened in pubs or hotels to keep them out of reach of the public.
All these improvements have been fantastic for the consumer & made using a TV more enjoyable than ever before. There has however been been one big casualty through this period. Sound quality.

Old fashioned CRT TVs
15 years ago, TVs were huge, not by screen size, but by sheer bulk. Larger TVs could be almost 2ft (600mm) deep & often had 4-6 inches (100-150mm) of plastic frame around the edge of the screen. A lot of this bulk was unavoidable & simply dictated by the size of the Cathode Ray Tube (CRT) technology that was used to produce the picture.

The up-side for this bulk was that speakers could be placed in less conventional positions. They were often placed behind the CRT itself with ports directing the sound out of grills at the front.

We also saw TVs that had sub-woofers on top of the CRT, sometimes inside the main casing, or inside an additional clip on unit. They were out of sight when watching the TV but added valuable depth to the sound quality.

The beauty behind this was that the designers didn't have to worry too much about the audio, they could fairly easily provide a quality of sound that all but the most critical viewer would happily accept.



The early flat-panel TVs

The early generations of flat-panel TVs didn't fare too badly with their sound quality. At the start, manufacturers overcame the space limitations by placing speakers at the side of the screens, at the bottom of the screens and by placing smaller bass speakers behind the screens.

Even so, the depth of these new TVs was a revelation compared to the old CRT sets and even this Panasonic from 2006, with a depth of 6 inches (150mm) was considered slim. The manufacturers were not adding depth to the sets to incorporate these speakers. They were simply fitting the speakers in around the vast amount of boards, heat-sinks & other components that were needed for the TVs to work.

By 2005, manufacturers had started to realise that the design of the TV was becoming almost as important as the picture & sound quality. The picture below shows how much the design of a 32" LCD from Panasonic changed from one range to the next. The later TV offered much sleeker lines and far less frame around the screen. The obvious speakers on the earlier set have been replaced with hidden speakers on the newer design but are still found either side of the TV screen.


Today's flat panel TVs

The trend for TVs to become more streamlined has continued & been made easier as components have got smaller allowing  more of then to be squeezed on to each circuit board. As this trend continued and further advancements such as LED back-lighting appeared, more pressure was put on the space needed to accommodate a decent set of speakers. At this point different manufacturers approached the design of their TVs differently, some sacrificed the size of the speakers to suit the styling of the TV, others sacrificed the styling in the pursuit of better sound. Fairly quickly it became obvious that the more stylish TVs were preferred by the consumer & if required extras speakers could solve the sound problem.

The picture above gives you an idea how far the casing around a Plasma TV has shrunk between 2004 & 2012. The later TV does have speakers built in, but watching anything other than a soap opera or the news may leave you feeling disappointed. You certainly wouldn't, by choice, want to watch the Proms or an action film as there would be many aspects of the audio missing from your experience.


The images above show a top-end 32" from 2006 compared with a mid-range 32" from 2012. It's quite clear how much smaller the newer TV is. The photo in the middle shows a speaker taken from an older LCD lined up next to a new set. The new set is almost half the depth of the speaker & graphically shows the reason why newer TVs have such poor sound reproduction, there is simply no room to do it.

It's a conspiracy!

We've had quite a few people coming in to our store saying that the poor sound quality is all part of a conspiracy from the manufacturers to make us buy additional equipment so we can enjoy TV. I can see where this idea has come from a consumers perspective but highly doubt that this is the case. One of the reasons I doubt this is because the degradation of sound quality has been a slow and continual process. If Panasonic, Sony or Samsung wanted to force people to buy home-cinema systems they would simply take the speakers out completely or would have jumped from the reasonable quality found in 2004 straight to today's standards for the 2005 range. They didn't do this & have been developing speakers ever since to try and maintain as much sound quality as possible. Unfortunately they are fighting an uphill battle against styling and consumer preference.
