The catch
KEF LSX II
Wireless linking removes the signal cable between speakers. Each cabinet still needs its power cable.
Side by side
KEF LSX II vs LSX II LT: No linking cable with LSX II, and only one power socket needed for LT
Quick verdict
Width and depth are identical at 155 mm and 180 mm, so the choice comes down to cables and power. LSX II is the pick if a doorway or separate furniture makes the cable between the speakers awkward and each speaker can safely reach power. LSX II LT fits when the cabinets share a clear cable route, since LT needs just one mains connection. LSX II also takes an analog line source, though an ordinary turntable still needs a phono stage. LT has no analog input whatsoever.
Before you buy
Why, and what it costs you
A single doorway can undo the cheaper model’s advantage
Picture a living room with the speakers on opposite sides of a doorway. LSX II can do without the signal cable across that opening, as long as each side has safe mains power. On a single console, LT can look tidier since only one cabinet plugs into the wall. Put the same pair at opposite ends of the room and the C-Link it requires becomes the constraint. Sketch both power routes and the interspeaker route before you choose. Neither option is cable-free.
Where this comes from
Connection layout applied to a hypothetical doorway setup. Nothing is assumed about wireless range, interference immunity or running cables across a walking route.
The catch
KEF LSX II LT
You can’t skip the C-Link. The supplied cable is 3 m long, and the longer 8 m version has to be bought separately.
KEF LSX II
- Why pick it
- Each speaker has a power socket close by, and a signal cable would otherwise have to cross a doorway.
- An analog source needs the 3.5 mm line input, and any preamp your turntable requires is sorted out separately.
- The catch
- Wireless linking removes the signal cable between speakers. Each cabinet still needs its power cable.
KEF LSX II LT
- Why pick it
- The speakers go on one desk or console, leaving room to route the C-Link cable they require.
- Compact KEF network audio is what you want, and you need neither an analog input nor a second mains connection.
- The catch
- You can’t skip the C-Link. The supplied cable is 3 m long, and the longer 8 m version has to be bought separately.

What this page compares
LSX II vs LSX II LT in a shared desk or TV room: how they differ on doorway cables, power sockets, turntable connections and the network-music setup they both need.
A buyer is most likely to weigh these two compact LSX systems against each other. The cabinets share the same published dimensions, which makes paying more mostly a question of connections and freedom in placement.

In practice
Differences you will notice
A single doorway can undo the cheaper model’s advantage
Picture a living room with the speakers on opposite sides of a doorway. LSX II can do without the signal cable across that opening, as long as each side has safe mains power. On a single console, LT can look tidier since only one cabinet plugs into the wall. Put the same pair at opposite ends of the room and the C-Link it requires becomes the constraint. Sketch both power routes and the interspeaker route before you choose. Neither option is cable-free.
How we worked this out
Connection layout applied to a hypothetical doorway setup. Nothing is assumed about wireless range, interference immunity or running cables across a walking route.
Adding vinyl down the road is a project of a different size
A shared household might begin with TV and streaming and add a turntable afterward. On LSX II there is a usable analog route once the turntable signal has gone through a suitable phono stage. LT has no analog input, so buying that same ordinary phono preamp doesn’t solve the connection. You would need some other conversion or streaming route, and its compatibility is something to check separately. If records are already on the shopping list, the original LSX II avoids that dead end. Its line input doesn’t make the phono stage unnecessary.
How we worked this out
A verified line input against no analog input. The consequence is about the connection chain and not a measured sound penalty from conversion.
Upgrading won’t get you a smaller desk setup
Picture a monitor in the middle and work papers on both sides. LSX II and LT take up the same cabinet width and depth. Each pair adds up to 310 mm of combined cabinet width before you account for spacing, toe-in and clearance. So the reason to pay more for LSX II is its connection flexibility. You get no desk area back. If the speakers stay beside one monitor and USB covers the computer, LT keeps the same compact body and the network-music options.
How we worked this out
Two cabinets times 155 mm comes to 310 mm, which is a sum of body widths and not a recommended installation width. Both published depths are 180 mm.

Spec by spec
Where they really differ
| Spec | KEF LSX II | KEF LSX II LT | In practice |
|---|---|---|---|
| Between the cabinets | Wireless signal link or wired connection | Required wired C-Link | With a doorway in the picture, this comes down to placement before it comes down to sound. |
| Power connections | Mains power at both cabinets | One mains connection powers the pair through C-Link | Check usable sockets on both sides of the layout you’re considering. |
| Analog source | 3.5 mm line input | No analog input | With the right cable, a preamplified turntable can feed LSX II. LT needs another source path. |
| Body size | 155 W by 180 D by 240 H mm | 155 W by 180 D by 240 H mm | Upgrading doesn’t free up any desk space. |
| TV and computer | HDMI ARC and USB-C audio | HDMI ARC and USB-C audio | Plain wired TV and laptop connections are already handled by both. |
Trade-offs
What each pick costs you
With KEF LSX II
- The analog input takes line level. If your turntable has no preamp, count a phono preamp in the cost of the whole setup.
With KEF LSX II LT
- No direct analog route into LT exists for a turntable, even with a normal phono preamp added.
Change of plan
When the answer changes
The real placement problem is the signal cable between the cabinets
Go with KEF LSX II. LSX II can link wirelessly provided both speakers can reach mains power.
Both speakers stay on one desk and all the sources are digital
Go with KEF LSX II LT. LT handles that setup with identical cabinet dimensions and a single power connection.
Decision guide
Before you buy
Fewer visible cables is the goal, yet power may only be available on one side of the room. Dropping the speaker link could swap one cable problem for another.
What this page can’t tell you
- There is no measured ranking for sound quality, loudness or reliability. How well network services and wireless work depends on the source and the home environment.
