“Modern televisions produced for the consumer market have a sound much worse than produced in Warsaw since the 70s, Soviet Rubin 714P” – says Dr. Gregory Augustine, acoustics. Is that really true? Viewing his opinion on the matter.
Do older TVs actually “sound better” than the new device?

Samsung has prepared for this year, a series of new television sets equipped with a refreshed version of the Smart TV Smart Hub. We test the data was flagship of the family F8500SL – TV Smart TV for $ 14 thousand. gold. read more
– Rubin had a large box, which housed the speaker cone with a diameter of up to 10 cm – said Dr. Gregory Augustine, acoustics industry specialist Audio Video, a member of Infocomm – Professional organizations plumbing company. – The membrane was working in a closed chamber or partially ventilated. Some at that time, more successful, TVs instead of a broadband transducer dysponowa?y even koaksjalnymi speakers (two speakers, woofer and tweeter in a coaxial design). And that speakers were directed to the side or forward, toward the viewer.
today? In an increasingly flat housing receivers for thin designer rameczk?, there is simply no room for quality speakers. TV manufacturers were against the wall. Transmitters are pressed, where exactly is the place, not where they should be found to play optimally. There are far too small. To get a decent sound quality, you need to move air well. Speakers 2.5 cm in diameter are not able to play a large capacity and at high volume levels, they’re not clean play. It is not surprising, since the higher-end hardware such a diameter tend tweeters, not full-range transducers.
– In one of my TV speakers were in the back, between the network outlets and a place on the handle – says Dr. Augustine. – Of course, the view of the material broadcast by television stations, is not enough. The more branded TV is better – there are sound projectors and passive membrane, ensuring a decent sound. But we are talking about the high price segment, where there is a space for innovation. The high price has also the fact that the series are shorter, so the cost of higher education, and besides, the price includes the cost of the service. But even if the TV formulate a “surround sound” or “stunning surround effects”‘s treat as marketing slogans. What we have today is Dolby Digital – mainly stereo or ProLogic, or a substitute for surround sound. Logic suggests that no matter how locate speakers in the TV, surround sound is not obtained.
says expert shoppers TVs can be divided into two groups. The first are those who bet the TV on a table, in a suitably prominent place in the living room, integrate into the slot antenna … that’s all. This just about bearable stereo sound quality, which will allow to understand words and hear the results, but a faithful reproduction of no way. The second group of customers buy the TV as a home theater component, so an assumption that it will be enclosed speaker system. For them, the sound he produces television, is of secondary importance. It aims to guarantee proper quality of the output signal, that is enough.
This division applies today, because soon it will change. When disseminate a television using OLED technology, the speakers will most likely disappear from television forever. Gregory Augustine consoles, although it’s not so obvious, because the solution for the super-thin TVs internal speakers would be in the form of thin panels on the surface radiation technology … But I guess we should get used to the idea that the buyer television would become adept skiing, which, buying skis, knows that to stand on the slope, has yet to buy some more binding and boots. And since we need to purchase an external TV audio, why the quality of the sound produced by it would not be finally equal quality?
Our comments
expert says that the solution to this problem may be an external speaker to the TV. He gives as an example of JBL Cinema SB200 (1399 z?) and 5.1-channel home theater system Harman Kardon HKTS 35BQ (3299 z?). These are only some of the examples. We had a chance to test Bose Lifestyle 135 – expensive (more than 10 thousand. Z?!), But very professional system. Soundbarów , and sets no shortage in the market, and indeed, they offer sound better than straight from the TV. But it’s probably not surprise anyone – you know it well since the 5.1 home cinema and DVD players. Or in total has been known even earlier, but after his debut Rubin.
