1. Identical speakers:
Neither "center-channel" speaker design nor "surround speakers"(e.g., bipolar) allow for precise control of all aspects of the surrounding space if the speakers are not identical. Therefore, ourdesign is based on adherence to one of our strongest beliefs, that only absolutely identical speakers are appropriate for audiophile quality, professional surround monitoring.
2. Match full-range speakers with appropriate subwoofer:
Deep bass extension in all surround speaker setups can causeextensive phase problems and makes speaker setup extremely difficult.
How can you have equal speakers with full frequency range but no bottom end around you? The only answer is to have excellent main speakers with lowest octave extension provided by front subwoofers.
There is also the practical aspect of limiting size and weight of the main speakers. Some phonographic recording use the subwoofer channel as a ceiling/center back channel. Then the sixth identical speaker should be installed in the back above the head of the listener.
3. Subwoofer concept:
Single or multiple front subwoofers should supplement bass extension for the main speakers, thereby making them full range.
Separate subwoofers also make setting up a room much more flexible.
Subwoofers have slight but noticeable influence on imaging. Even sharp, low-pass filters allow for some bleeding above 100Hz which is directional. Therefore we recommend front firing woofers. For the same reason we recommend rather two wide-spread front subwoofers instead of one.
4. Passive speakers:
Our laboratory tests indicate that when an amplifier is built into a speaker, second harmonic distortions can rise up to 15 percent! This was also confirmed in our blind listening tests. The problem was recognized by some High-End audio manufacturers using extra dampening material for enclosures of standalone amplifiers to avoid vibration caused by speaker proximity.
5. Mono block amplifiers:
How can you place the amplifier very close to the speaker, without attaching it to the speakers' enclosure? Our solution is to use a mono block amplifier built into the speaker stand. Line level cable length is not as destructive to sound quality as the length of the speaker cable. Subwoofer amplifiers should be designed with a different approach than main speaker amps.
6. Short speaker cables:
Our extensive experiments with top rated speaker cables clearly indicate that a quality, short length cable elicits better sonics than a superb quality, longer cable.
7. Speaker Stands 36" and 30":
The height of the tweeters should be set to the listener's ear while the subject is in a sitting position. Since 36" speaker stands are almost impossible to find, we designed and custom manufactured our very own.
8. Surround Monitoring Console:
The console should have the cleanest possible signal path and should have some features that are not available on today's market.
Availability to be anounced.
9. Matching components:
Unlike other audio manufacturers, we do not "tweak" the inaccuracy of one piece of equipment with an adjustment of another component (e.g. frequency response of speaker equalized with amplifier, etc). Each component must be state-of-the-art on its own. Only at the very end, do we evaluate the system as a whole.
