As one of Samsung’s lower-end soundbar and subwoofer combos for 2016, the HW-K450 keeps things simple. Its plain, wire mesh exterior doesn’t have any fancy embellishments or distinguishing features, but at least its small, compact design means it won’t distract from your TV.
Measuring 908mm long, this soundbar is best suited to TVs that are at least 42in in size – any smaller and the soundbar will begin to dwarf the length of your set. Still, when it only stands 53.5mm high, it’s pretty low-profile, so it should fit quite happily underneath most TVs, and it certainly shouldn’t obscure the IR receiver if you end up placing the soundbar in front of it.
Ports and connections
It might be small, but that doesn’t mean the HW-K450 is short on ports, and it packs a surprising number of connections for such an entry-level soundbar. As well as Bluetooth support, you’ll find an auxiliary input, optical S/PDIF, a Micro USB port and a pair of HDMI ports in two sculpted cut-outs on the underside of the soundbar, allowing you to wall-mount it without worrying about the wires sticking out the back.
One of the HDMI ports is a standard input, but the other is an ARC (audio return channel) output. This means you can have another device connected to the HW-K450, such as a Blu-ray player or games console, using the input slot, and still only have one wire going into the back of your TV.
This is extremely handy for cutting down the number of cables in your home cinema setup, but Samsung TV owners can eliminate the need for wires altogether thanks to the HW-K450’s SoundConnect support. Most Samsung TVs dating back to 2012 should have this feature, and it’s extremely easy to set up, taking less than ten seconds overall. Simply set the soundbar’s source to TV, and your TV will detect the soundbar automatically. The HW-K450 automatically pairs with its accompanying subwoofer as soon as you turn it on, too, so it couldn’t be simpler to get going.
Of course, with just a 2.1 channel system at its disposal, the HW-K450 isn’t exactly an audio powerhouse despite its total RMS output of 300W. It’s definitely a step-up from your TV’s built-in speakers, with the subwoofer providing some much needed bass and warmth to the overall soundscape, but I found that dialogue could be quite muffled during films, particularly if there was an accompanying soundtrack playing at the same time.
Quieter scenes were perfectly audible, but climactic action sequences often lost a lot of their impact due to the muddy dialogue. It didn’t really improve when I switched the sound mode from Standard to Movie, either, and low, rumbling sound effects could also be rather underwhelming. The roars and crumbling buildings in Godzilla, for example, could be felt through my sofa, but the final confrontation scene in The Dark Knight Rises was much less powerful, as its punches, gun shots and crashing tanks just didn’t deliver the kind of force and intensity I was expecting.
My other soundtrack tests also sounded a little flat at times, although setting the soundbar to Music mode certainly helped to improve its overall clarity. However, it still struggled to separate out all the instruments in my How to Train Your Dragon 2 soundtrack, for example, and classical tracks such as Lizst’s Liebestraum No.3 were also rather lacking in nuance. Vocal tracks, such as Sondheim’s Company soundtrack, could be particularly shrill and grating, too.
Other genres, on the other hand, such as rock and pop songs from artists like Muse and Lady Gaga sounded perfectly fine, producing deep, punchy audio that really gets your foot tapping. Still, it’s clear that the HW-K450 isn’t the most versatile soundbar, so it may not be particularly suitable if you have a specific kind of music taste.
One useful feature it does have is a Night mode, which cuts down on the amount of bass produced by the subwoofer so you don’t disturb your neighbours quite as much when you’re watching films late at night. The effect was fairly subtle, but I found it worked better when the volume level was set to below 20. There’s also a virtual surround sound setting that artificially widens the soundbar’s listening area, but it didn’t make a huge difference to my overall audio experience.
To help get the sound quality just right, the HW-K450 lets you adjust the bass, treble and subwoofer settings using the Sound Control button on the small, bundled remote. Again, you’ll be hard-pushed to notice the difference between its twelve respective steps of treble and bass options, but the subwoofer controls should definitely come in handy, if only to dampen it further when you’ve got Night mode enabled.
The HW-K450 isn’t the most impressive soundbar I’ve ever heard, but it does provide a fairly inexpensive way to boost the quality of your basic TV speakers. At this kind of price, though, it faces stiff competition from the Steljes Audio Calliope, which has better overall sound quality despite its lack of dedicated soundbar. Its display might be as subtle as Samsung’s, but you also get an extra HDMI input for your trouble.
Admittedly, the HW-K450 does give you the option of expanding your audio setup to a 4.1 channel system at a later date by pairing it with Samsung’s various multiroom speakers. However, when even its basic R1 speakers cost around £170, you’d simply be better off buying a superior, more capable soundbar, such as Samsung’s own HW-K650, rather than shell out for additional satellite speakers. The HW-K450 might have plenty of flexibility for a budget soundbar, but its overall quality isn’t quite up to scratch.
