[ Mission 엘레강트 북쉘프 E50 ]
Mission’s ‘Paramid’ driver is formed using a sandwich structure. Aramid polymer fibres with incredible tensile strength are sandwiched between two stiffer pulp layers. This creates a cone which is very light and stiff, yet has superb internal damping. The internal damping drastically reduces cone-induced distortion by absorbing the transverse waves that travel through a cone following an impulse.
Symmetrical driver array
symmetrical configuration of drivers is used to improve dispersion and to improve imaging, Placed equidistant above and below the high-frequency driver, mid-range and bass drivers create an even horizontal dispersion and a controlled dispersion on the vertical plane.
Having the treble unit centrally placed enhances the imaging by mimicking a point-source dispersion. Interference patterns when a stereo pair of speakers are used create an almost holographic sense of presence with the listener able to discern the exact location of instruments and voices within the soundstage.
IDG (Inverted driver geometry)
Mission has pioneered the use of inverted driver geometry. By placing the treble unit below the bass or mid-range driver, the length of path so the waves coincide at the listener’s head-height is equalised. This principle is known as ‘time-alignment’.
Some manufacturers use electrical correction to achieve the same effect, but by using IDG, Mission loudspeakers achieve the same objective without disruption to the delicate mid-range frequencies. The result is a very natural and coherent presentation.
Audiophile grade crossover
Mission use advanced computer modelling to theoretically produce an optimum response and minimum phase shift through each crossover point. This is then refined through critical listening tests and panel evaluation to produce an ideal performance.
Our audiophile crossovers include components to reduce the effects of driver impedance peaks which would otherwise cause unwanted phase shifts through the crossover region.
Crossover components are chosen for their specific audio qualities, mounted on custom designed PCBs for minimum interaction and mounted using soft resin to dampen any mechanical interference.
All moving coil loudspeakers use some kind of magnet system to produce the movement within the voice-coil. The magnetic field, if unshielded can affect CRT televisions if placed in proximity to the field.
Mission use an inverted field shielding system and neodymium ‘rare-earth’ magnets which have a very concentrated flux density over the plane of the axis, but very little leakage towards the side of the magnet (and speaker).
All our magnetically shielded loudspeakers are ideal for use in close proximity to all television sets or wherever magnetic interference is an issue.
Direct Coupled Crossover
The objective of any internal loudspeaker design is to transmit as much of the music as possible to the drivers with the fewest possible components in the way to degrade the signal. By mounting the crossover section directly to the rear loudspeaker terminals, the signal path is shortened and number of internal connections reduced.
Gold has both exceptional electrical conductivity, and is also relatively malleable. When used for electrical connections, it creates a larger contact area and a lower resistance – both ideal for preserving the optimum signal quality.
Bi-wire terminals are used to allow the bass and high frequency sections of a loudspeaker to be wired independently. Although all bi-wireable loudspeakers are supplied with ‘bridging’ clips, so that a single wire can be used if desired.
Although the maximum benefit of bi-wiring is achieved through using two sets of amplifiers with different channels driving the bass and treble frequencies, there are still significant acoustic advantages to running two sets of cable (or a specialist bi-wire cable) from a single set of amplifier outputs.
When bi-amping (using two stereo amplifiers) with bi-wire speakers, it is recommended for each amplifier to be driving a bass and treble unit of one speaker, rather than having one amplifier driving both treble units and the other both bass units.
High grade OFC (Oxygen free copper)
Copper is an excellent electrical conductor, however, oxygen impurities within the crystalline structure can adversely affect that conductivity. By refining the copper to a much higher grade of purity, resistance can be further reduced for the best possible electrical conductivity and hence signal quality.
Heatsink cooled treble unit
Maintaining a consistent temperature in a treble unit is essential for a consistent performance, even at high volume levels. Heat is generated by current within the voice-coil and this needs to be controlled to avoid compression and even damage to the unit.
Mission’s new heatsink coupled treble units conduct heat away from the treble unit very effectively, keeping control and maintaining a consistently high standard of dynamic performance.
Treble voice-coil are fine wires and tend to get very hot when used for a long time, or at high volumes. This can cause distortion and compression if the excess heat cannot be removed.
Ferrofluids are used in treble drive units to sink heat between the voice-coil and the magnet assembly. They also passively damp the movement of the cone. They reside in what would normally be the air gap around the voice-coil, held in place by the speaker's magnet.
Neodymium magnets (NdFeB) are one of a class known as ‘rare-earth’ magnets. They are also sometimes known as ‘super-magnets’ because of their unbelievable strength and small size.
They are ideally suited to audiophile loudspeaker applications because of their strength, low weight, small size and their thermal stability.
Die-cast chassis are a huge improvement over plastic or even pressed steel units. Because of the manufacturing technique used, they can have a more complex three dimensional shape, hence are much stronger.
Because of their higher strength, they can be manufactured with an open frame design. This allows air moving backward from the cone to flow and be absorbed within the cabinet rather than being reflected back through the cone. There is an obvious improvement to mid-range clarity and timing.
