So as you can see, doubling the amount of power you can drive a speaker at does not mean you’ll double the volume. It increases it a very small amount (as far as your ears are concerned). Also, attempting to wire two 8 ohm speakers in parallel to an 8 ohm stereo would have the same effect. (Two 8 ohm speakers in parallel is equal to 4 ohms total that the amp will see) The Sharp HT-SBW460 is one of a limited number of budget soundbars to support Dolby’s surround-sound technology, Atmos, and it delivers surprisingly effective virtual height effects given its price. The bar uses four front-firing drivers to successfully convince your brain that certain sounds are coming from above you, and also does a great job of positioning effects to the left and right of the soundstage. If space underneath your TV is at a premium but you’ve got room to accommodate a reasonably large subwoofer for added low-end impact, this is the budget soundbar for you. The key thing to know about optical is that it's restricted in bandwidth compared to ARC/eARC. So if you have the choice between the two and opt for optical, you might not be making the most of the audio decoding built into your soundbar. The most advanced immersive formats optical can handle are compressed Dolby Digital or DTS 5.1 surround sound, so that means no Dolby Atmos or DTS:X.
The least powerful bar on this list, the Roku Streambar, is able to fill a reasonably sized room with sound. What’s the best way to connect a soundbar? With its wide range of supported audio formats, the A7000 excels itself and includesDolby Atmos(in both the Digital+ and TrueHD formats),DTS:X, LPCM, hi-res wireless audio and Sony 360 Reality Audio. Although soundbars are typically designed with film and TV in mind, we also put them through their paces with music too, testing out a range of streaming options with a variety of genres, both classic and modern, enduring that we listen in the highest quality that the soundbar is capable of. Some soundbars will come with pre-programmed modes for different types of content. In our experience, soundbars with cinematic modes often use 'spatial' processing that can introduce high-frequency artefacts. In contrast, 'music' modes will usually have a bass and treble-heavy EQ that can sound a little brash. We tend to favour a flat standard mode, if one is available, that we manually adjust to our liking. But there is no one size fits all approach that will work for every room and listener.Ideally, we would recommend going all in on an AV amplifier and matching home theatre speaker system, but in reality, we understand that not everyone has the space and/or the budget for something like this. That's why we recommend a soundbar as a great alternative. Home stereo and car speaker wiring typically use a red or plus sign “+” to indicate the positive polarity for the speaker wiring terminals to connect your wiring to. The main upgrade on the PS-949 (aside from its bigger sound) is the addition of app support, which comes as an alternative to the physical buttons on top of the speaker. When it comes to sound input, the speaker supports wireless streaming via Bluetooth, as well as wired connections with both USB and aux-in. You can also pair two PS-949s in Duo Mode to enable left and right channel stereo sound from a single Bluetooth source. ARC/eARC also allows your main TV remote to control the basic volume and power functions of your soundbar via HDMI CEC(Consumer Electronics Control). Some soundbars come with their own remotes and/or have app control, but if your connection to your TV uses an optical cable, you may still be able to use your regular controller. Certain models, such as the Sonos Ray and B&W Panorama 3, can 'learn' to recognise the commands of both IR and RF remotes, but the set-up will depend on your TV manufacturer.
The number of channels present in a soundbar is represented by two digits separated by a full stop. The first digit reflects the number of primary channels, while the second indicates the presence of a subwoofer to handle low-end frequencies. So, a 2.0 soundbar possesses two audio channels – left and right – while 2.1 bars add a third via a subwoofer. The size of the soundbar is primarily down to the larger-than-enough drivers Sennheiser has managed to fit in, and the result is a sound big enough not to need its own subwoofer, with clear, direct dialogue and detail and subtlety in spades. The way it stretches the sound around you creates a great atmosphere and really draws you into the action.As we note in our review: "While some soundbars with external subwoofers go deeper, the bass here is delivered with weighty gusto and seamless integration. This is what helps the Sennheiser achieve the sort of effortless, natural tonality and texture that most rivals can’t begin to match." But the best thing about the Ambeo Max's sound? How little attention it draws; "there's none of the beamy, nasal harshness found in many other soundbars and on the whole, the processing is natural and convincing." With a water resistance rating of IPX4, it should be able to withstand a splash of water if you take it to the pool or spill a drink on it. This is a bit lower than the IPX5 rating on the PS-919, but still higher than the PS-929 which doesn’t have an IP rating. Fortunately, most soundbars have speech enhancement feature settings that will typically raise the volume of the centre channel and crispen up the EQ to help improve dialogue audibility. Not every brand implements this with sophistication, and sometimes these modes can sound thin and harsh, but once again, it's always worth experimenting to find what works for you and your space. How we test soundbars How we test soundbars We have state-of-the-art testing facilities in London, Reading and Bath, where our team of experienced, in-house reviewers test the majority of hi-fi and AV kit that passes through our door and allow for plenty of listening time as well as running them in before we begin reviewing.
So, if you don’t mind a bit of audio DIY, the Sharp HT-SBW460 is an attractive choice, but if you’d rather not tinker, you’re better off losing the extra audio channel and buying the Creative Stage 360 instead. Speakers, much like other electromechanical devices, all have an electrical resistance to the flow of electrical current, much like a standard resistor, a light bulb, or many common items you’re familiar with. Speakers contain a long wound loop of wire called a voice coil. Loops of wire have a property called inductance which affects a speaker’s resistance value depending on the frequency (sound range) being played. Soundbars are slim, often rectangular, speaker systems with drivers positioned side by side that are designed to slot underneath your TV or to be fitted neatly to the wall. With front-facing drivers, even basic, budget soundbars typically offer more direct and clear audio than a TV. This is because of how the human ear works and the physics of sound, along with how speakers work and how much volume they can produce for a given amount of power.
However, this is a speaker with practicality and affordability in mind. Its ultra-compact dimensions, tapered build and forward-facing speakers mean it takes up little space and removes any need for a clear line of sight for upward- and side-firing drivers, making it a practical choice for small rooms and even desktops. We’ll go through all of its different connectivity options – Wi-Fi, Bluetooth, HDMI, stereo, optical etc. – and then proceed with assessing its sound quality across each supported method, across whatever channel configurations are possible, using a range of audio sources. There are a few options to improve your TV sound that range from the budget to the expensive, but a soundbar is one of the simplest ways as they are typically compact and require minimal cabling. They often also have added benefits, such as wireless streaming over Bluetooth or WiFi. There is little more frustrating than not being able to hear dialogue when watching a TV show or movie, but inevitably, varying levels of speech clarity combined with how busy the soundscape is and the overall style of the mix can mean that whispery, mumbly vocals hinder even a top-quality, room-tuned soundbar. As they have electrical properties that include inductance and capacitance, their “total resistance” can actually change with the music slightly. Because of this, there’s some extramath needed to figure out the total resistance.Sound quality is impressive too, with virtual surround sound reasonably effective given the limitations of a 2.0-channel setup and plenty of ways to customise your audio experience. That customisation extends to the Katana SE’s LED lighting too, which won’t be everyone’s cup of tea but is an essential inclusion for some gamers.
