Head-to-head

KEF LSX II vs LSX II LT: LSX II removes the linking cable, LT needs only one power socket

The short answer

Choose LSX II when a doorway or separate pieces of furniture make the interspeaker cable awkward, and both speakers can reach power safely. Choose LSX II LT when the cabinets share a clear cable route and LT needs only one mains connection. Both are the same 155 mm width and 180 mm depth. LSX II also accepts an analog line source, but an ordinary turntable still needs a phono stage. LT has no analog input at all.

Before you choose

The reasoning and the trade-offs

One doorway can reverse the cheaper model’s advantage

Imagine a living room where the speakers sit on opposite sides of a doorway. LSX II can remove the signal cable across that opening, provided each side has safe mains power. LT can be tidier on a single console because only one cabinet plugs into the wall. Move the same pair to opposite sides of the room and its required C-Link becomes the constraint. Draw both power routes and the interspeaker route before choosing. Neither option is cable-free.

What this is based on

Connection topology crossed with a hypothetical doorway layout. No wireless range, interference immunity or permission to run cables across a walking route is assumed.

Main trade-off

KEF LSX II

Wireless linking removes the signal cable between speakers, not the power cable at each cabinet.

Main trade-off

KEF LSX II LT

The C-Link is mandatory. The supplied cable is 3 m, and the longer 8 m version is an extra purchase.

About this comparison

LSX II or LSX II LT for a shared desk or TV room? Compare doorway cables, power sockets, turntable connections and the setup both need for network music.

These are the two compact LSX systems a buyer is most likely to compare. Their cabinets have the same published dimensions, so paying more is mainly a decision about connections and placement freedom.

Winner by situation

Start with what you need it to do

  • Speakers straddle a doorway and both sides have power

    LSX II can remove the interspeaker signal cable. Its power cables still need safe routes.

  • One console with a clear cable route and one power point

    LT powers the secondary speaker over its required C-Link.

What matters in practice

The differences that matter

One doorway can reverse the cheaper model’s advantage

Imagine a living room where the speakers sit on opposite sides of a doorway. LSX II can remove the signal cable across that opening, provided each side has safe mains power. LT can be tidier on a single console because only one cabinet plugs into the wall. Move the same pair to opposite sides of the room and its required C-Link becomes the constraint. Draw both power routes and the interspeaker route before choosing. Neither option is cable-free.

How we reached this conclusion

Connection topology crossed with a hypothetical doorway layout. No wireless range, interference immunity or permission to run cables across a walking route is assumed.

Adding vinyl later is a different-sized project

A shared household may start with TV and streaming, then add a turntable. LSX II has a usable analog route once the turntable signal has passed through a suitable phono stage. LT has no analog input, so buying the same ordinary phono preamp does not solve the connection. You would need another conversion or streaming route and should check its compatibility separately. If records are already on the shopping list, the original LSX II can avoid that dead end. Its line input does not make the phono stage unnecessary.

How we reached this conclusion

Verified line input versus no analog input. The consequence concerns the connection chain, not a measured sound penalty from conversion.

The upgrade does not buy a smaller desk setup

With a monitor in the middle and work papers on both sides, LSX II and LT occupy the same cabinet width and depth. Each pair accounts for 310 mm of combined cabinet width before spacing, toe-in and clearance. Paying more for LSX II therefore makes sense for its connection flexibility, not for recovering desk area. If the speakers stay beside one monitor and USB covers the computer, LT preserves the same compact body and network-music options.

How we reached this conclusion

Two cabinets multiplied by 155 mm gives 310 mm, a body-width sum rather than a recommended installation width. Both published depths are 180 mm.

What you give up

Every choice has a cost

If you choose KEF LSX II

  • The analog input is line level. Include a phono preamp in the whole setup cost if your turntable lacks one.

If you choose KEF LSX II LT

  • A turntable has no direct analog route into LT, even after adding a normal phono preamp.

Recommendation switch

The decision flips if...

The signal cable between cabinets is the real placement problem

Choose KEF LSX II. LSX II permits wireless linking if both speakers can reach mains power.

The pair stays on one desk and every source is digital

Choose KEF LSX II LT. LT covers that setup with the same cabinet dimensions and one power connection.

What matters in practice

Before you choose

You want fewer visible cables, but the room may have power on only one side. Removing the speaker link can create a different cable problem.

Check these before buying

  • Measure the cable route, not just the straight-line speaker separation.
  • Check home-network compatibility and complete KEF setup and firmware updates. Guest networks can require administrator help.

What this comparison cannot tell you

  • No measured sound-quality, loudness or reliability ranking. Network services and wireless performance depend on the source and home environment.
