Yamaha's YAS-152 soundbar is wide. The box suggests that it's "for 55-inch, 60-inch, 65-inch and Larger TVs". Which is why it measures 1200mm. Standing 108mm tall, its two legs are a bit over a metre apart and keep the body some 29mm above the bench. That ought to let it sit above the part of a TV's pedestal that protrudes to the front. It's 136mm deep, so in terms of volume it's fairly substantial. You can attach the unit to a wall using the pre-attached mounting points.
Either way, the underside needs to remain clear because there are two speaker drivers mounted there, firing downwards. These are 85mm units and their job is to deliver the bass. These are apparently wired together to provide the bass in mono (this typically has almost no effect on stereo imaging), receiving 60 watts of total power. The enclosure is a bass reflex design (in which the bass is extended by careful tuning to allow the energy from the rear of the speaker cones to be employed, enhancing output). The ports are at both ends of the bar.
The upper frequencies are delivered are delivered by a pair of 65mm midrange/treble drivers, each supplied with 30 watts of power. These are located within a couple of centimetres of the extreme ends of the bar and fire forwards.
The unit is finished in a shiny black plastic, with only a row of LED function indicators and some small push button controls to break up the expanse. Should the body of the unit obscure the IR remote control sensor at the bottom of your TV, this unit will re-transmit the signal from an emitter at its rear.
At the back, set well into the body, are four inputs: optical digital audio, coaxial digital audio and two sets of analogue stereo audio (one via RCA sockets, one via 3.5mm stereo). The fifth input is Bluetooth. The unit can decode such things as Dolby Digital and DTS sound.
There's a compact remote that comes with the unit and also Yamaha apps for both Android and iOS (it's called HT Controller). This works via Bluetooth, so you'll need to pair and connect to the unit to make use of it.
It's rare to hear a AU$500 soundbar speaker that sounds good with music, but this one manages to pull it off. It does this by delivering surprisingly high volume levels with very little distortion; by delivering the music with an extremely good tonal balance; and by providing realistic bass levels down to its cut-off. Indeed, the bass was so good I figured I'd better measure it. The bass kicked up to a small peak at around 65 hertz, and settled back down to the regular level at 55 hertz, falling away rapidly below that point.
