Audio Optimum MS6E

The MS6E monitor system differs from its predecessor, the MS6, by having external electronics to avoid microphonic effects and replacing the side passive membrane with an airflow-optimized bass reflex port, which significantly enhances bass dynamics. Both changes make the MS6E superior in sound quality and maximum volume even compared to the larger predecessor, the MS8. The MS6E is an unrivaled monitoring system for smaller control rooms, delivering on what advertisements usually only promise:

1. The MS6E requires no acclimation period, saving you time right away. No matter which monitors you’ve worked with before, you can continue your production with the MS6E and rely entirely on what you hear without abstraction. Your production will finish faster, and the result will be better.
2. The MS6E makes secondary or tertiary monitors obsolete. What sounds flawless on the MS6E will sound good on all other playback systems.
3. The MS6E enables fast, precise, and fatigue-free work at any volume level. Its sound quality is at least on par with even the most complex high-end playback systems, regardless of size or price.
4. The MS6E scrutinizes the entire recording chain, from room acoustics to microphones, cables, preamps, limiters, effect devices, etc. Everything that can be optimized in detail becomes immediately audible. However, the MS6E is not "over-analytical"; the wholeness of music reproduction remains intact.
5. The MS6E serves as both a perfect studio monitor and a high-end audiophile speaker. The high-end version, the MS6EH, with two SINCOS MonoAmps, is identical to the studio version except for stronger power transformers and larger capacitors (in unregulated power supplies, some degree of over-dimensioning is sensible). Only a completely uncolored speaker can assert itself with identical tuning in both professional studio operations and commercial use. This is achieved through an unprecedentedly precise, phase-parallel analog active crossover in combination with the ideal power amplifier based on the internationally patented sinus-cosine modulator principle.

The MS6E monitor system includes, as standard, two 3.3m special cables with 4 x 2.5mm² copper cross-section for connecting the 4-channel amplifier in the 19-inch/2U housing to the speakers. Each pair of wires is twisted together. The two twisted pairs are enclosed by a braided cotton sleeve, a natural material that prevents static charge and remains acoustically neutral. Poor 4-core cables, such as those used for PA systems, degrade sound quality to such an extent that it's better to integrate the electronics into the speaker boxes and accept the microphonic effects!

On the other hand, sound quality can be further improved if each twisted pair is encased in a basalt fiber braided sleeve, and both twisted pairs are enclosed in a larger basalt sleeve. Basalt contains a certain amount of iron oxide, which minimizes both mutual electromagnetic interference between the two twisted pairs and external interference from high-frequency magnetic fields, without damping the high-frequency reproduction in the audible audio range. Due to the complex manufacturing process, the 4-core basalt cable is only available at an additional cost. However, for precise, fast, and relaxed work in the studio, the extra investment in the basalt cable is highly recommended. Although there is no measurement method for this yet, no bat-like ears are required to hear the difference clearly. The basalt cables make the sound clearer and the spatial imaging more precise.

Experience shows that all electrical connections in a music reproduction system longer than 30cm, whether high- or low-impedance, should be regarded as "cables," where both the conductors and insulators (dielectrics) of each cable can audibly affect sound quality. For all Audio Optimum speakers, the internal wiring is therefore already made with basalt-sheathed twisted pairs as standard.
