Audimaxim S-5 Actives

audimaxim S-5 information

The designer drew on the design of the LS 3/5A bass horn unit, which was improved. The box height of AUDIMAXIM Music Master S-5 is 230mm, the width is 160mm, and the depth is 207mm. The volume is equivalent to that of LS3/5A, and it also uses a closed box design. S-5 In order to obtain sufficient volume while maintaining sufficient rigidity under a limited volume, aluminium alloy is used as the material for the entire speaker cavity.

The front barrier plate of the speaker is made of 6063T high-strength aviation aluminium with a thickness of 15mm. The horn unit is directly locked on the strong front barrier plate to reduce the resonance transmitted to the cavity; while the cavity is made of one-piece stretched aluminium. Profiles, one-piece molding can reduce the chance of air leakage

At the same time, the distortion of the box caused by the stress between too many mechanical structures is also avoided. In order to modulate the intrinsic resonance of the metal surface, the profile adopts different thicknesses and adds reinforcing ribs inside, while attaching butyl rubber to the inner wall of the cavity to absorb vibrations, further reducing the resonance.

The sound-absorbing material inside the box uses two different materials. It is surrounded by high-density polyester fibre cotton and filled with long fiber ultra-fine down cotton. For a closed box, this filling method can be equivalent to increasing the cavity volume. It can also maintain a moderate "air spring" effect, greatly reducing the distortion of bass. 

Let’s take a look at the technical indicators of AUDIMAXIM Music Master for all-aluminium alloy box active bookshelf boxes: frequency range: 60Hz-30KHz (+2dB), 50Hz-32KHz (+5dB) and its off-axis phase response is at ≤45° It's still as high as 13KHz, which is very rare for high notes Thanks to the precise oval shallow horn design on the heavy solid aluminium front barrier plate of the Music Master S-5, the diffraction diffusion of medium and high frequency frequencies is more uniform and the diffusion angle is wider.

Such excellent off-axis response data is of course also related to the physical characteristics of the independently developed and designed AMT pneumatic treble unit. The treble unit of the S-5 is the AMT "Hale" pneumatic treble of the AUDIMAXIM music master. The Haier-style treble has a diaphragm area that is larger than that of the general ball. The top treble is much larger, so the distortion is smaller at the same sound pressure level. This pneumatic treble folding diaphragm material that has been improved many times controls the thickness to 0.0125mm on the basis of maintaining sufficient rigidity. Such a thin and rigid material can maintain sufficient output energy even at a frequency of 30KHz. The high-frequency performance is more delicate and smooth, and the powerful rubidium-iron-boron magnetic circuit gives treble excellent transient characteristics.

The mid-bass unit uses modified glass fiber braiding material to make a cone. This modified glass fiber is characterised by the weaving method and the damping glue treatment on the back. It has better acoustic characteristics than Kevlar and has both high stiffness and suitable damping. It can effectively control sound division and vibration, can recover quickly after each vibration of the unit, and has excellent transient response The voice coil uses high-purity copper-silver-plated enamelled wire, and the computer-aided optimised design of the magnetic circuit allows the speaker BL value and voice coil inductance to maintain high symmetry under long-stroke piston motion, greatly reducing distortion;

At the same time, the AUDIMAXIM Music Master S-5 adopted a newly formulated synthetic rubber material for the bass suspension of the mid-bass unit S-5, which is more durable than the usual rubber suspension, and simulated the shape of the suspension under long-stroke motion through a computer. The suspension was segmented and strengthened by adding spiral pit grooves Dramatically reduce the distortion of suspended edges during large-scale movements. This 5-inch mid-bass horn also uses a huge high magnetic flux Y-35 constant magnet and a strong and thick cast aluminum basin frame. Whether it is based on the hierarchy and transient response of sound or large-scale dynamic performance, it can be compared with the 5-inch flagship mid-bass units of many horn manufacturers today Coupled with the heavyweight box made of 100% aluminium alloy made by AUDIMAXIM Music Master S-5, the resonance is lower than the frequency that the human ear can feel, so the sound is clean, open and natural, clear without being shrivelled, plump without being fat, and the sound details and overtones will be richer.

As a shoebox-sized speaker, each AUDIMAXIM Music Master S-5 speaker has a built-in 150-watt Class D large amplification circuit tailor-made for it. This newly designed Class D amplifier has strong suppression capabilities against the back electromotive force. It has obvious advantages for driving low-sensitivity closed speakers. The difference between the S-5 and traditional active speakers is that it abandons the use of electronic frequency division or digital processing for frequency division and frequency correction processing in traditional active speakers. It uses a traditional passive frequency division network to avoid the signal passing through the DSP processor. Sound quality degradation caused by multiple A/D and D/A conversions. In addition, S5 active audio also abandons the popular wireless design this year and eliminates crosstalk between digital lines and analogue amplification, thereby obtaining wide, flat, and low-distortion frequency response characteristics.

The small cabinet has excellent dynamic and pleasant sound quality, which is a rare high-quality active speaker, high-quality tabletop fever active speaker. We can think of the AUDIMAXIM Music Master S-5 as an advanced audiophile speaker with built-in mono rear-level amplifier. It can achieve good sound effects by connecting it to a multicast with volume control or a small pre-stage, and connecting it to a Bluetooth adapter or multicast. (Basically all with Bluetooth and webcast functions) It is a pair of wireless speakers Of course, the higher the quality of the predecessor and the sound source, the better its sound state will be. Hundreds of thousands of predecessors and sound sources will not be called shortcomings. It is paired with a multi-thousand-dollar digital broadcast with volume control. 

It is no exaggeration to say that at this time, the dynamics of the S-5, the sound density of the full frequency band and the texture of the sound, the body feel, timbre and analytical power of the instrument can reach the quality of many high-end bookshelf boxes worth tens of thousands of yuan, so this We are not in this review for this unconventional front-end system matching, because it is difficult to imagine that it is impossible for ordinary enthusiasts to match it this way However, designers of AUDIMAXIM music masters must have extremely high-quality front-end systems for comparison when developing products, so it is normal for the R&D department to match them like this
