FOUNTEK NeoPro5i RIBBON TWEETERS
115x190mmm OVER-SIZED HIGH-POWER PROFESSIONAL RIBBON TWEETER PAIR
NeoPro5i ribbon tweeter is a premium grade, high-performance component
best suited to large high power professional installation solutions.
incredibly efficient transducer is capable of very high SPL yet
faithfully maintain a sound quality that surpasses any other kind of
high frequency transducer. The large diaphragm also enables a lower
resonant frequency of only 400Hz enabling better crossover
characteristics and an impressively broad frequency range that will
match to many types of speaker arrays, easily and efficiently, with
audiophile sound quality.
Super strong Neodymium magnet for high
efficiency. Built-in impedance conversion transformer. Effective from
850Hz upwards due to the large diaphragm area and low self-resonance.
Super thin Enforced-Sandwich Ribbon diaphragm guarantees a high degree
of signal fidelity and broad frequency response. Low distortion factor,
60W Nominal power-handling capabilities, linear impedance with linear
amplitude and broad frequency response.
Very high flux, NOT shielded, so NOT suitable for near TV applications.
Manufacturers Recommended Crossover Frequency is 1.5KHz 2nd-order or above
Independent assessment, comments:
Neo Pro 5i is an excellent high sensitivity pure ribbon tweeter for
high end home theatre and music speaker system applications. The Neo
Pro 5i Ribbon tweeter applications include Low to medium power High End
class A Transistor / FET or Valve amplifiers using high efficiency
Woofer / Tweeter speaker combinations. Thus enabling Triode/Pentode
valve amplifiers with only a few watts of output power to reach
incredible sound pressure levels with very low harmonic distortion. Due
to the high power handling capabilities of the new Alloy sandwich
diaphragm the Neo Pro 5i Ribbon tweeter can also be used for High End
Studio or High power PA monitor speaker systems requiring the extra
detail and distortion free sound and transient dynamics of a ribbon
tweeter. The Neo Pro 5i is a true pure ribbon tweeter with incredible
dynamics ,sound stage ,depth of field, midrange detail, and shimmering
top end to kill for.
is a high power ribbon tweeter designed for High power Home Audio and
Professional Audio. The ribbon diaphragm is made up from an advanced
composite material, total thickness only 20 micrometers, normal
operation temperature is 240 degree Celsius. This material provides
extra strength and guard Aluminum layer do not oxidation. The diaphragm
suspension make up from high temperature soft rubber material. It makes
diaphragm keep optimum tension, and damping resonance from the ribbon.
The magnetic strength determines efficiency in a ribbon transducer.
NeoPro5i assembled 4 pieces highest quality Neodymium magnet in a heavy
U-York. The surface magnetic strength is 1 Telsa. Typical ribbon
diaphragm self-impedance is very low, so a practical ribbon tweeter
must assemble an impedance matching transformer. The impedance matching
transformer is very important to products consistency. All impedance
matching transformers are hand built and 100% measured by
high-precision instrument. Close quality control make sure product?s
