I would avoid it unless you are mainly just watching TV or don't require high output levels or are sitting relatively close. Or look at the R3/R300 models.
Yes, everyone knows that a 2-way coaxial is one of the hardest speakers to engineer. Additionally, everyone knows that a 3-way done right can over come some of the limitations of a 2-way. KEF, has done both for ages and the LS50 derives from all of the previous R&D on monitors and the Blade.
The LS50 Wireless is a remarkable achievement for a small bookshelf 2-way active system that can play pretty clean past moderate levels. One can ALWAYS spend more money on the latest and greatest 3-way speaker. However, someone that wants a simplified setup for clutter free living spaces, not to mention WAF, an all-in-one active solution is becoming a popular option. Many are companies are offering them now. Yes, KEF is trying to capture some of the non-Audiophile streaming consumers out there however, there are some in the 1% audiophile community that want simplified great sounding rigs that don't take over a room. Some have already purchased the LS50 and LS50 wireless for duty outside of near-field listening. LS50's are in main rigs and multi channel dynamic theater systems. Speaker topology talk, 2-way distortion talk aside, the speakers are performers and sound good! I'm sure some of these owner could and would go with 3-way speakers if they wanted.
OTOH, the OP could very well go out and get the R11 towers powered by a couple of huge and powerful monoblocks and even add in a couple of Rythmik Audio F15HP 15" subs. This would be more in line with his original post and thinking. Plus, the system will provide enough sound for even the largest rooms in a typical 2000-3500 sq ft home. However, he asked to be stopped from doing so and wants to keep the space less cluttered with audio gear. The R3 and a sub will get him the new sound and tech he is chasing and will mate well with a small space saving integrated amp like the Creek Audio, Peachtree, Rega, Hegel, Naim, Belles, Jolida, Emerald Physics, Nuprime, Parasound, Vincent Audio, Devialet, etc. The LS50 Wireless + sub will drive the cost, and space saving down even further. Only the OP knows what will work.
Its nice to have so many option in 2018.
