KEF LS50 Wireless vs B&W 606 Speaker Comparison

In this review, we will be comparing LS50 Wireless and BW 606, two Bookshelf speakers from KEF and Bowers Wilkins. The main difference between these two speakers is that the KEF LS50 Wireless is a Powered speaker which means that it has a built-in amplifier inside the speaker body so you don't need an external power amp or an integrated amp whereas the B&W 606 is a Passive speaker so has to be matched with an amplifier to get any sound from it.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.

Cabinet Type and Port Position

Both LS50 Wireless and BW 606 have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.

If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.

Physical Specs

Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare KEF LS50 Wireless's and B&W 606's external dimensions. KEF LS50 Wireless has external dimensions of 301.6 x 200.0 x 336.5mm ( 11.875 x 7.875 x 13.25inch) whereas B&W 606 has external dimensions of 345.0 x 190.0 x 324.0mm ( 13.5 x 7.4 x 12.7inch) .

B&W 606 is 10mm narrower and 12.5mm less deeper than KEF LS50 Wireless but it is also 43.4mm taller.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited. The base surface area of the KEF LS50 Wireless is approximately 673.0cm2 / 104.3inch2 and base area of the B&W 606 is approximately 615.6cm2 / 95.4inch2. The LS50 Wireless requires 9% more surface area than the BW 606 which gives it a small disadvantage on placement in tight spaces.
