Constituent part of the body of the horn are wooden, gold-plated (24 carat gold) res-
onator leaf and resonator cube, placed in the channel to control clangs and echoes.
There is no crossover. A custom made copper cable is used in the internal wiring.
Our sistem fulfills active bass horn as inseparable part of the whole completely
authentic and peculiar only to Ring Audio. By its construction subwoofer is clasical
conical horn. Subwoofer has an internal amplifier and a digital crossover as integral
parts of it.
Thanks to its simple design and dimensions MasterHorn speaker can easily fit into
any room. Finish could be made of wood by choice of a customer (layered), lac-
quered layered MDF in different colours or veneered by choice of customer. Sphere
at the top of cabinet is made in composite coloured in black or white.
3.3. Drive unit
Drive unit used in loudspeakers is Fostex Fe 108E Sigma 4". It is specific for its
exceptionally light diaphragm (2,2 gr) made of pressed banana plant's fiber. During
implementation into horn, driver is treated with specially prepared acetone lacquer of
negligible mass in order to be "sound-tight". Very light diaphragm, strong magnets
and flawless UDR construction enable violent, completely flat vibration of the
diaphragm without additional micro excursions that results in extremely high resolu-
tion. The sphere in which it is implemented serves as a supprabaffle to correct baffle
step loss to a minimum.
Driver used in subwoofer is Visaton W250S - 25 cm (10") HiFi woofer with strong
drive, extended rear pole plate and 38 mm voice-coil for high power handling. Elastic
rubber surround, coated paper cone and magnet vent.
3.4. Subwoofer internal amplifier
Internal amplifier used in subwoofer is Hypex DS 2.0. It is class D amplifier module
for active subwoofer use. Accurate rendition of the low bass range is a substantial
component of a high-quality music reproduction. For an impressive bass rendition
large loudspeakers are inevitable. The crossover frequency is adjustable steplessly
between 20 Hz and 120 Hz. Due to this large range of control a problem-free connec-
tion is possible to different subwoofer and other loudspeaker systems. Additionally
this active system has a low bass rise. An active 4th order subsonic filter with
Butterworth characteristic protects the loudspeaker against mechanical overloading,
since the ultralow portion of the fed signal would cause extreme diaphragm deflec-
tions.
4. Positioning
Due to its dimensions and features MasterHorn speaker can be placed anywhere in
the room. There are no precise distances acquired for speaker to be placed from the
wall.
Nevertheless, the best results in Hi Fi reproduction are achieved by positioning the
speakers minimum 1,5 m from the side wall and 1,5 m from the rear wall; speakers
should be distanced cca 2,6 m from each other and slightly turned toward listener.
Place the speakers so that you are at the same distance from each. The distance
between the speakers should be the same as between you and the speakers.The sub-
woofer should be placed between the speakers. MasterHorn - Jazz has very strong
polar characteristic so it creates a sound volume that corresponds with the area
around in the way that sweet spot almost doesn`t exist. This is one of its greatest
virtues. It is a result of precise mathematical calculation, a sphere in which a drive
unit is placed and the lack of a crossover with all of its electronic elements. Therefore,
