Cambridge Audio Minx X301 Review

The Cambridge Minx X301 subwoofer is intended, first and foremost, to enhance the sound of a TV . It has won over a large number of consumers who wanted to improve the audio of their television shows without investing too much. In terms of performance, the new Cambridge Minx X301 subwoofer did better than the previous model.

With less than 30cm of side, the Cambridge Minx X301 subwoofer ranks among the smallest on the market. Despite this, it is able to produce a surprising level of bass thanks to its 300 watt amplification responsible for feeding its 20 cm speaker supported by a passive radiator of the same size.

High quality Technologies

Delivering a bass of incredible intensity and depth for a subwoofer of this size, the Cambridge Minx X301 is surprising. And since it’s compact, it can be placed anywhere in the room, even behind the sofa, which won’t prevent it from adding warmth and density to any soundtrack. Cambridge engineers have designed a sophisticated digital signal processor (DSP) for this subwoofer, providing real-time control of EQ settings and dynamic range processing. It enables the Cambridge Minx X301 subwoofer to deliver optimum performance, while preventing the risk of overloading and distortion to the speakers. The Cambridge Minx X301 can thus handle the strong increases in power and produce an imposing sound volume without failing.

The Cambridge Minx X301 subwoofer uses a specific speaker coupled to an ABR (passive radiator) system rather than a closed load (which would require even more power) or a bass reflex design (which would require a larger cabinet) . It is thus capable of producing extremely efficient and powerful bass, despite its tiny size. The Cambridge Minx X301 subwoofer has gain, phase and crossover frequency control on its rear panel. There is also the connection (RCA input / output compatible LFE ) as well as the on / off switch and the automatic on / standby selector.

Equally at home in hi-fi in a 2.1 stereo configuration or home cinema in a 5.1 system, the Cambridge Minx X301 subwoofer adapts to all situations. Its small size, its nice finish and its various settings allow it to be placed and adjusted easily, for perfect integration into the living room.

Digital Signal Processor

Cambridge engineers have designed a sophisticated DSP to provide real-time EQ and control, as well as dynamic range processing, to obtain the best possible performance and avoid overloading and distortion of the transducers. This allows Minx subwoofers to handle more power and produce an even more punchy sound.

Sleek and thunderous

Both subwoofers (X201 and X301) use a highly advanced driver and ABR (Auxiliary Bass Radiator) system rather than a sealed cabinet system, which would require more power, or a bass-reflective cabinet system, which would require larger dimensions. The result of this system is two powerful, highly efficient subwoofers in small structures.

Musical and vocal performances

Listening to Charlotte Cardin’s song Crazy Anywhere, the Cambridge Minx X301 subwoofer produces a clear sound that gives the listener a sense of closeness to the music. This sound definition is especially heard at high and medium frequencies. The bass doesn’t offer much precision. 

The subwoofer also has a modest output which gives it enough precision to respond to just about any musical genre and, most importantly, does not suffer from the effects of buzzing

Quality of finish

The Cambridge Minx X301 subwoofer has a more modern and practical design than the previous models. Its 10.5 inches width makes it one of the few subwoofers from a recognized brand that can harmonize with small screens.
