Subwoofer Brax Matrix ML8 SUB

The legendary BRAX MATRIX range of loudspeakers, for many years synonymous with top quality sound, is now complemented by the ML8 SUB. Developed and manufactured as uncompromisingly as all BRAX loudspeakers, this subwoofer is an acoustic benchmark to be reckoned with.
Using a new 2 x 2 Ohm dual voice coil, the ML10 SUB allows for the most flexible connection configuration, and therefore makes it possible to achieve extremely clean and maximally controlled bass reproduction more easily than ever before. Separate voice coils with four massive connection terminals allow three different configurations - 1 x 4 Ohm, 2 x 2 Ohm or 1 x 1 Ohm with an extraordinary maximum power of up to 1200 Watts.

MicroSphere – the perfect synthesis of weight and stiffness

One of the secrets of the BRAX ML8 SUB lies in its unique membrane, more precisely in its "MicroSphere" coating. It provides the hand-picked diaphragm with the highest level of acoustic precision for unparalleled reproduction. This patented technology embeds ceramic hollow spheres with a diameter of only 75 µm in a polyamide layer that is applied to the membrane. This special coating not only improves the stiffness but also the internal damping of the membrane. However, these stabilization measures do not increase the moving mass. Compared to other subs, the cone is even lighter, which not only results in a lower overall Q factor, but also further improves impulse response.

"Engineering at its finest" in harmony with timeless elegance

Every BRAX product impresses with its purist design and perfect workmanship in every detail - and the BRAX ML8 SUB is of course no exception! Its extremely linear magnetic drive with precision-machined pole plates for the lowest level of distortion, a large, multi-vented voice coil for maximum electrical power handling and an aerodynamically shaped and stable die-cast basket guarantee uncompromising bass reproduction at the highest level. Of course, the ML8 SUB is delivered in a noble wooden box with its own serial number, which is recorded in the service database.

The main features of the Brax Matrix ML8 SUB subwoofer

An exceptionally stiff hand-picked paper diaphragm with a unique "MicroSphere" coating consisting of microceramic hollow spheres embedded in a polymer layer offers the best possible impulse response.
Specially shaped rubber edge for long linear movement of the membrane.
Dual 2 x 2 Ohm voice coil with exceptional winding height for high linear deflection and lowest possible distortion.
Optimized voice coil ventilation using large holes in the T-Shape and basket protected by mesh for almost zero compression effects and maximum heat dissipation.
Specially developed, aerodynamically optimized and extremely strong aluminum die-cast basket.
Extremely powerful and precisely machined magnetic system for the highest linearity of the magnetic flux.
Massive push clamps for large wire cross section.

RMS powerThe RMS power of the subwoofer is the constant power of continuous use of the subwoofer. If the power is exceeded for a longer period of time, irreversible damage may occur, or to burn out the voice coil of the subwoofer.	400 W
Max. (maximum performancePeak performance , which the subwoofer can play momentarily (approx. 0.5 s), for example when hitting drums in a song. If the maximum power is exceeded, damage can quickly occur, or to burn out the voice coil of the subwoofer.	800 W
Sensitivity (SPL 1W/1m)Subwoofer sensitivity or efficiency. The sensitivity of the subwoofer is given in decibels (dB) and, in simple terms, means that the higher the value, the lower the demands on the power of the amplifier. This is a de facto rating of how a subwoofer converts watts to sound. Sensitivity ratings are in noise level measured at 1 meter from the subwoofer using 1 W (watt of power) or using 2.83 volts at the source at 1 meter. A higher decibel level means the subwoofer is louder with less power. For every 3 dB increase in sensitivity, the subwoofer requires half the power to reproduce the same volume. For example, if an 88 dB subwoofer needs 300 watts to produce a certain volume, then a 91 dB subwoofer needs only 150 watts to reach the same efficiency.	88 dB
ImpedanceImpedance - measurement of electrical resistance. When buying a subwoofer, it is very important that everyone make sure that the impedance matches the amplifier that you are connecting to it. For subwoofers with a double voice coil, we recommend following the information in the advice center! Example: A 2 Ohm subwoofer cannot be connected to an amplifier that is only stable up to 4 Ohms. A 4 Ohm subwoofer can easily be used on an amplifier that is stable up to 2 Ohms. Connecting a 4 Ohm subwoofer to an amplifier that is stable up to 4 Ohms also without problems. The most common subwoofer impedance is 4 Ohm.	2 + 2 Ω
Subwoofer diameterThe diameter of the subwoofer is indicated on the screw holes. The overall outer diameter of the subwoofer is usually 1-2 cm wider, depending on the size category of the subwoofer. For a 30 cm subwoofer, the outer diameter incl. protective rubber 31.8 cm and in the 25 cm subwoofer it is 26.5 cm incl. protective rubbers.	200 mm (8")
Subwoofer mounting depthThe mounting depth of the subwoofer is measured from the bottom edge of the magnet to the bottom edge of the subwoofer's metal or cast basket.	95,6 mm
Recommended enclosure volumeThe closed enclosure is characterized by a simple construction. Closed enclosures are usually smaller than bass-reflex enclosures, and a special damping fleece is used for their damping. A closed baffle has the advantage of preventing an acoustic short between the front and back radiation of the subwoofer diaphragm. The disadvantage is that the closed enclosure raises the natural resonance frequency of the used subwoofer and thereby also increases the lower limit frequency. This is because the back side of the diaphragm is forced to compress and dilute the air inside the enclosure when the subwoofer is radiating in a closed enclosure. This adds to the inherent stiffness of the subwoofer's oscillation system the stiffness of the air in the closed enclosure. This causes an increase in the stiffness of the oscillating system and thus an increase in the resonant frequency of the entire system: subwoofer -> loudspeaker. The increase in resonant frequency for a given subwoofer is greater, the smaller the volume of air in the closed enclosure. The relatively small volume of air in the closed enclosure acts on the subwoofer as an acoustic spring when radiating the back side of the membrane into the enclosed enclosure. USE: Mainly for quality bass listening in the entire band with an emphasis on detail and accurate reproduction in the lower band. Pros and cons: + pure reproduction + small closets + easier tuning - low level of efficiency in deep bass - loudness only at the cost of enormous deflection of the membrane - a significant acoustic pressure cannot be expected	17 L
Xmax + -Xmax - the maximum deflection of the subwoofer diaphragm in one direction – it is not a sum, or an abbreviation for the maximum linear deflection. The subwoofer output becomes non-linear as the voice coil begins to leave the magnetic gap.	+/- 9,2 mm
