Cambridge Audio L/R Speakers: Which Model Fits Your Room?

Which Cambridge Audio L/R speaker should you choose?

Our starting point: L/R S for a desk or compact wired system; L/R M for music, TV and vinyl in one room; and L/R X when your main system needs greater output and bass capability. Then we look at where you sit, what you connect and how you listen.

Before we talk about watts, tell me where these are going.

On either side of a computer? Across the living room? Next to the television, with a turntable nearby? Those are different jobs. A speaker can be a very good product and still be the wrong choice for the way you want to use it.

That is how we look at Cambridge Audio’s L/R family. All three models put amplification inside the speakers, so you do not need a separate amplifier.

The L/R S can be the heart of a small stereo system. Add a CD player through its RCA line outputs or optical output, or connect a turntable through a suitable phono preamp. If your turntable has a phono preamp built in, set it to line output and connect it directly to the S’s RCA inputs. If it does not, a separate phono preamp goes between the turntable and the speakers. Start with the music source you own and add another later—the S gives you more room to build a system than its size might suggest.

The M adds built-in network streaming and more ways to connect your sources. The X takes that fuller system concept and gives it more output capability and deeper specified bass extension.

So the useful question is not simply, “Which one is best?” It is, “What am I asking the system to do?”

Two speakers still matter.

If your music currently comes from a single Bluetooth speaker—a JBL on the counter, for example—you already know how convenient that can be. But most of the sound reaches you from one spot. Even when a single speaker plays both channels of a stereo recording, there is only so much space between them.

Separate left and right speakers give the music room to open up. A singer can appear between the speakers, with a guitar to one side and other instruments arranged around them. Instead of everything coming from the same little box, you begin to hear the space in the recording. Give the speakers some separation and sit roughly the same distance from each, and familiar songs can become much more engaging.

You can make that move with the L/R S. Start with your phone over Bluetooth and enjoy a proper stereo pair; a CD player or turntable can come later. You do not have to stretch to the M just to get into stereo.

Active speakers let you pursue that experience without choosing a separate amplifier. The manufacturer can design the amplification, drivers and processing together. You are buying a system, even if it looks like two boxes.

The trade-off is worth understanding: you cannot change the amplifier independently later. If choosing components and upgrading them one at a time is part of the fun for you, separates still have a very good reason to exist.

Choose the L/R S for your desk or a small stereo system.

The L/R S is a proper stereo system in a compact pair of speakers, with the amplification already built in. It can be your first step beyond a single Bluetooth speaker, a system for a smaller room, or a very enjoyable way to listen at your desk. Bluetooth, USB-C audio, optical and RCA line inputs give you several ways to get started. [1]

Use your phone today. Connect a CD player through its RCA line outputs or optical output. Add a turntable using its built-in phono preamp, or a separate one if needed. There is also a subwoofer output if you later want to add more bass. You can build around the music you already own without buying a separate amplifier.

The M adds the convenience of built-in Wi-Fi streaming, HDMI eARC and an MM phono input. Those are useful features, but they are not requirements for enjoying CDs, records or music from your phone. If the S suits your room and budget, it can be the system you keep—not something you have to outgrow.

Give the speakers a stable surface, some space between them and a reasonably balanced position around your listening seat. Tell us about the room and how loudly you listen, and we will help you judge whether the S is the right fit.

Choose the L/R M when music, television and vinyl share a room.

The L/R M is where the family becomes a more complete source hub. StreamMagic handles network streaming; HDMI eARC accommodates a compatible TV; an MM phono input accepts a suitable moving-magnet turntable setup. [2]

That changes the buying conversation. You are now comparing the cost and footprint of an entire system, rather than comparing the price of these speakers with a passive pair that still needs an amplifier and sources.

The M is the one I would start discussing when space matters but you want more than a desktop arrangement. Do not buy the X automatically because it is the flagship. First tell us how far away you sit, how open the room is, and how loud you actually listen.

Choose the L/R X when this is the main system.

The L/R X is the model to examine when you want the convenience of the M with greater scale in the design. Cambridge specifies 800 watts across the pair, two 5-inch woofers and two 6-inch passive radiators per cabinet, and a 35Hz–24kHz response at ±3dB. [3]

Here is the part that interests me: headroom is useful even if you do not listen loudly all the time. Music has peaks. A drum strike, a piano attack or a sudden orchestral swell asks more of a system than its average listening level suggests. The reason to investigate the larger model is what it can do with those demands in your room—not the chance to put a bigger number on a shopping list.

Those are reasons to audition it, not a promise that a compact speaker will do everything a large floorstander can do. Listening distance, room volume and bass expectations still count. This is a buying guide based on the published designs, rather than a claim that we have completed a comparative listening test.

The differences that affect your decision.

Manufacturer figures are useful reference points, not a measurement of performance in your room. Room-use suggestions are House of Stereo’s guidance. Sources below.

A few things we would sort out before you order.

Streaming is more than Bluetooth.

With the M and X, built-in network streaming means you do not need to add a separate network player just to get started. Check the services and control methods you use before buying. An aptX logo on the S does not make it the more complete streaming system.

Do not bury the speakers in furniture.

Start with sensible placement and then use the available adjustments. Give the cabinets breathing room, avoid blocking drivers, and listen from your usual seat. Processing is useful; it does not make the furniture disappear.

A subwoofer is a system decision.

All three provide a subwoofer output. That gives you an option, not an obligation. We would look at the room, your music and the bass you want before adding one. A well-integrated sub can be valuable; an unnecessarily loud one can dominate everything you liked about the speakers in the first place.

Check the cartridge, not just the turntable.

The M and X phono inputs are for moving-magnet use. Do not assume every cartridge is a direct match. Tell us what you own and we will work through the connection with you.

Where we would begin.

If this is a desk or small-room system, start with the S. If you want streaming, TV and vinyl in a compact arrangement, start with the M. If you are building your primary listening system and asking for more output and bass capability, put the X on the shortlist.

Then let’s talk about the room. That is how we get from a good product to a system you actually enjoy.
