But many enthusiasts don\u2019t like the lack of easy upgradability or the low perceived value &#8211; active speakers are, inevitably, always far more expensive than their passive relatives due to the cost of the power amplification inside. And, of course, a pair of active speakers only goes so far &#8211; you still need to add a preamp and a range of sources too.<\/p>\n<p>But what if you didn\u2019t need to add those extras? Imagine active speakers with preamp functionality; something that includes digital and analogue inputs.<\/p>\n<p>Such a device\u00a0would certainly need Bluetooth, and perhaps even streaming services such as\u00a0Tidal\u00a0built-in. You know what would also be nice? A streamer, so that any music stored on a NAS unit or computer connected to your home network could be replayed.<\/p>\n<p>Such well-equipped active speakers would not only get rid of the clutter of traditional hi-fi\u00a0but also, if done properly, could potentially deliver a performance broadly equivalent to a similarly priced separates rig.<\/p>\n<p>The good news (as you may have guessed&#8230;)\u00a0is that such a product does now exist: KEF\u2019s LS50 Wireless.<\/p>\n<h3 class=\"section-title closed processed\">Build<\/h3>\n<p><a href=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_03.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"alignnone wp-image-7764 size-medium\" src=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_03-300x201.jpg\" alt=\"\" width=\"300\" height=\"201\" srcset=\"https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_03-300x201.jpg 300w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_03-768x515.jpg 768w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_03.jpg 790w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>While we\u2019ve reviewed powered and actives options from the likes of\u00a0Dynaudio,\u00a0Dali,\u00a0Linn\u00a0and\u00a0Meridian\u00a0before, none of them has combined such a wide range of features in such an elegant two-box format.<\/p>\n<p>Those that offer a range of inputs usually add an extra connection hub that transmits the signal wirelessly to the speakers. That\u2019s not the case here. There are just the two fully active speaker boxes, arranged in a master and slave configuration. All sources connect to the right (master) speaker, which is then linked to the left by means of a supplied ethernet cable.<\/p>\n<p>As is usually the case, &#8216;wireless&#8217; doesn\u2019t actually mean wireless. While these KEFs are better than most, you still have two mains leads \u2013 one for each speaker \u2013 and the connecting lead between them. Still, they remain a neater solution for getting high-quality sound into the home than traditional separates.<\/p>\n<p><a href=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-2.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"alignnone wp-image-7765 size-medium\" src=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-2-300x201.jpg\" alt=\"\" width=\"300\" height=\"201\" srcset=\"https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-2-300x201.jpg 300w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-2-768x515.jpg 768w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-2.jpg 790w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>It will come as no surprise to any regular reader that the Award-winning passive\u00a0LS50s are the basis for this design. The drive units remain unchanged.<\/p>\n<p>These speakers use a Uni-Q array, where the 25mm aluminium dome tweeter sits in the centre of a 13cm magnesium\/aluminium mid\/bass cone.<\/p>\n<p>This arrangement helps to produce an even dispersion of sound and improves integration between the two drivers. What looks like a grille in front of the tweeter is, in fact, a waveguide that improves its performance.<\/p>\n<p>That beautifully built and finished enclosure is the same as the passive version too, bar a couple of centimetres of additional depth to accommodate the electronics and heatsinking. There are three cabinet options: the Titanium of our review samples, gloss black and gloss white. Each option comes with a contrasting colour on the Uni-Q driver array.<\/p>\n<p>That curved front panel still looks unusual and is made of DMC (Dough Moulding Compound: a polyester resin combined with glass fibre and calcium carbonate). DMC was chosen for its inertness and ability to be shaped.<\/p>\n<p>The rest of the enclosure is made from MDF. It\u2019s heavily braced and strongly damped to minimise any resonances. We don\u2019t tend to talk much about ports, but the one here is unusual in that it\u2019s flexible in a bid to reduce distortion.<\/p>\n<h3 class=\"section-title closed processed\">Features<\/h3>\n<p><a href=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_07.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"alignnone wp-image-7766 size-medium\" src=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_07-300x201.jpg\" alt=\"\" width=\"300\" height=\"201\" srcset=\"https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_07-300x201.jpg 300w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_07-768x515.jpg 768w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_07.jpg 790w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>These are true active speakers where each drive unit has a dedicated power amplifier. A 30W Class A\/B circuit feeds the tweeter while a 200W Class D module powers the mid\/bass unit.<\/p>\n<p>The Class D design was chosen for its combination of high power and low heat output \u2013 heat generation is an important consideration in a product as crammed as this.<\/p>\n<p>KEF has taken advantage of the internal DSP by phase correcting the crossover and using the software to allow the speakers to play loud and true while minimising distortion.<\/p>\n<p>The digital signal path is 24-bit\/192kHz capable and there\u2019s a dedicated DAC for each drive unit. Only the optical input is limited to 96kHz signals, but that\u2019s not unusual.<\/p>\n<p>Take a look at the back of the right speaker and you\u2019ll find stereo analogue, optical and USB Type B connectors. You\u2019ll also find a subwoofer connection, in case you want to add more low frequency output, and an Ethernet socket for connecting to your network.<\/p>\n<p><a href=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"alignnone wp-image-7767 size-medium\" src=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-300x201.jpg\" alt=\"\" width=\"300\" height=\"201\" srcset=\"https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-300x201.jpg 300w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless-768x515.jpg 768w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef-ls50-wireless.jpg 790w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>Normally we\u2019d recommend sticking to the wired network option for greater stability but we used the twin-band (2.4gHz\/5GHz) wireless option for most of our test without issue.<\/p>\n<p>There are also controls for adjusting the sound for different speaker placements with options for close-to-wall or free space positioning as well as the choice between desk or stand supports. These choices can be made from the dedicated iOS\/Android app too.<\/p>\n<p>That app looks nice, is well laid out and easy to use. It controls the streaming (DLNA as well as Tidal) functionality and allows plenty of scope to fine-tune the speaker\u2019s performance in a given environment. There is room for improvement, though. It\u2019s a little glitchy and feels unresponsive at times.<\/p>\n<p>We also don\u2019t like the sliding volume control. It doesn\u2019t change the volume until you lift your finger, so you don\u2019t know how loud the sound is going to be until you hear it. It can shock on occasion.<\/p>\n<p><a href=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_04.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"alignnone wp-image-7768 size-medium\" src=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_04-300x201.jpg\" alt=\"\" width=\"300\" height=\"201\" srcset=\"https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_04-300x201.jpg 300w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_04-768x515.jpg 768w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_04.jpg 790w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<div class=\"field-item odd\">\n<div class=\"field-collection-view clearfix view-mode-full\">\n<div id=\"section73460\" class=\"entity entity-field-collection-item field-collection-item-field-sections-collection clearfix\">\n<div class=\"content section-container closed\">\n<div class=\"field field-name-field-body field-type-text-long field-label-hidden\">\n<div class=\"field-items\">\n<div class=\"field-item even\">\n<div>\n<p>It\u2019s important to note that the app doesn\u2019t switch between physical inputs, as it only operates the KEFs in streaming mode. To change input, you need to use the supplied remote or the touch controls on the master speaker.<\/p>\n<p>This swapping around of controllers gets a little annoying if you switch sources a lot, particularly as the app has to reconnect with the LS50s every time you switch back, rather than just working straight away.<\/p>\n<p>It would also be nice to be able to see an indication of the input chosen when sitting at the listening position \u2013 the only indicator is out of sight on the right speaker\u2019s top panel. So if you\u2019re using the remote to change input there\u2019s no way (apart from counting clicks) to know what input the LS50 has settled on.<\/p>\n<p>None of these things are anywhere near serious enough to be deal breakers for us, but they make living with the speakers a fussier experience than it should be. Make no mistake; you\u00a0<em>will<\/em>\u00a0want to live with them.<\/p>\n<p>Why? To our ears they sound at least as good as the best comparably featured separates combinations available for similar money. Remember, here there are no extra electronics to house or cables to hide, just a pair of beautifully built speakers on (ideally) a pair of stands.

The LS50 Wirelesses sound clean and precise. They dig up so much detail and deliver it in an organised and stable manner. We\u2019re struck by the KEF\u2019s subtlety and their ability to generate strong dynamic shifts without stress.<\/p>\n<p>These are small speakers but they manage to fill our medium sized listening room with high volume levels. KEF claims a maximum sound pressure level of 106dB, which should be loud enough for most people in most circumstances.<\/p>\n<p>Positioned with care, a little away from the rear wall and with a touch of toe-in towards the listening position, they render a lovely, expansive soundstage that\u2019s neatly layered and nicely defined.<\/p>\n<p>We try the LS50s in less optimised positions and manage to use the app to make the results sound balanced. They\u2019re never quite as good as the optimal position in terms of outright clarity or stereo imaging, but tonally we still get a balanced presentation.<\/p>\n<p><a href=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_05.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"alignnone wp-image-7770 size-medium\" src=\"https:\/\/www.abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_05-300x201.jpg\" alt=\"\" width=\"300\" height=\"201\" srcset=\"https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_05-300x201.jpg 300w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_05-768x515.jpg 768w, https:\/\/abtec.co.nz\/blog\/wp-content\/uploads\/2017\/12\/kef_ls50_wireless_05.jpg 790w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p>Once set-up properly we think KEF\u2019s engineers have struck a really nice tonal balance.
