Compare KEF's LS50 Wireless II and LSX II powered speakers. Learn the key differences in sound, connectivity, and price to choose the right one for your space and budget.
Quick answer
Choose the LS50 Wireless II if you want the highest-resolution wireless sound and have room for larger cabinets. Pick the LSX II when you need a compact, all-in-one system that still delivers high-fidelity audio for smaller spaces.
Size and placement matter
The LS50 Wireless II is a larger bookshelf speaker designed for dedicated listening rooms or living areas where you can place them on stands or shelves with enough breathing room. The LSX II is noticeably more compact, making it easier to fit on a desk, a sideboard, or a smaller shelf without sacrificing the core KEF sound signature.
If you plan to use your speakers near a wall or in a tight space, the LSX II’s smaller cabinet and rear porting are more forgiving. For open spaces where you can pull the speakers away from boundaries, the LS50 Wireless II’s larger drivers and cabinet volume deliver a noticeably bigger soundstage.
Connectivity and sources
Both models support AirPlay 2, Chromecast, Spotify Connect, and Tidal, plus wired inputs for TV, games consoles, and turntables. The LS50 Wireless II adds an HDMI ARC port for easy TV connection, while the LSX II includes HDMI ARC as well. Both let you stream from virtually any source without a separate receiver.
The key practical difference is that the LS50 Wireless II offers a more premium DAC and amplification section, which matters if you plan to use high-resolution streaming services or connect a high-end turntable. The LSX II still sounds excellent, but its electronics are tuned to match its smaller driver and cabinet.
Trade-offs at a glance
- Soundstage and power: The LS50 Wireless II uses a larger 5.25-inch driver and more powerful amplification, producing a wider soundstage and deeper bass without a subwoofer. The LSX II uses a 4.5-inch driver and is still very capable, but it can't match the LS50's dynamics in a large room.
- Price and value: The LS50 Wireless II is priced at $1,829.99 (catalog comparison $2,999.99), while the LSX II is $899.99 (catalog comparison $1,499.99). The LSX II offers a more accessible entry point to high-fidelity wireless audio, while the LS50 Wireless II justifies its premium with greater output and refinement. If your budget allows and you have the space, the LS50 Wireless II is a long-term investment in sound quality.
- Room fit and placement: The LSX II is significantly smaller and easier to place on desks, shelves, or near walls. The LS50 Wireless II needs more space around it to perform its best. Measure your listening area before deciding. For desktop or small-room setups, the LSX II is the more practical choice.
