RoomMagic is Cambridge Audio’s new room correction, and it just landed on the L/R X and L/R M as a free update. No mic stand required. Your phone does the measuring. Room correction usually means a measurement microphone, a laptop, a license fee and an afternoon of tweaking, and this one skips all of it.
Cambridge Audio built RoomMagic in-house with the same team that designed both speakers, and it ships inside the StreamMagic app as version 4.5.0. Update the app and the speakers.

Two measurements and your phone does the rest
The app walks you through setup step by step, from where to stand to where the phone goes. One measurement calibrates your phone’s own microphone, and the second, taken from your listening spot, measures the room itself. Whole thing takes minutes.

Then you can flip between before and after in the app and hear the change. A bad room gets bigger fixes while a well-behaved one gets smaller ones.
The rollout began November 11, new pairs ship with RoomMagic built in from the factory, and Cambridge Audio says the feature keeps developing inside StreamMagic from here.
The bass gets the attention
Rooms do the most damage down low, so RoomMagic concentrates on the bass first. Above the bass, corrections stay small and land just where the room causes a clear peak in the response. Headroom, dynamics and the speaker’s own character stay protected, which is the part hi-fi people will care about.

You pick the bass. Leaner, Balanced or Fuller switch instantly after measuring, with no re-measuring and no extra gear to buy or lose, and an intensity slider runs from the original sound to full effect.
Which speakers get it, and which one misses out
RoomMagic lives in the two StreamMagic models, the flagship L/R X at $2,299 a pair and the smaller L/R M at $1,599. Real Walnut adds $100. The L/R M is on sale in the UK now. Cambridge Audio puts US availability in early December. Both pairs carry a moving-magnet phono stage, so a turntable like Cambridge Audio’s Spira plugs straight in.

The little L/R S gets nothing here. It’s the Bluetooth-only model with no StreamMagic inside, so there’s no app for the update to arrive through, and no RoomMagic at the end of it. It still takes USB Audio and an RCA input, so a laptop or a turntable can plug straight in.
