Tweeter Features
◆ Neodymium Magnets
The high ionic compound of neodymium enables a smaller tweeter
magnet assembly to be used as opposed to the much larger ferrite magnets
that are commonly used in speaker manufacturing.
THE RESULT: An efficient magnet which allows smaller tweeter
construction.
◆ Magnetic Fluid Cooling
Magnetic fluid is a synthetic liquid consisting of microscopic magnetic
particles. The fluid has four times the thermal conductivity as air which
makes it an ideal cooling agent. Magnetic fluid is injected into the voice
coil gap which helps dissipate heat generated by the voice coil.
THE RESULT: A thermal conductor which allows increased power
handling.
◆ Swivel Mount Design
The tweeter is encapsulated in a variable swivel housing. This design
allows direct dispersion of the tweeter in order to accommodate various
mounting positions. The swivel mount design allows the tweeter to
maximize its sonic potential.
THE RESULT: Precise tweeter imaging regardless of mounting position.
Crossover Features
◆ Adjustable Tweeter Level Matching
The passive crossovers utilize a series power resistor for tweeter level
matching. The factory set tweeter output level is 0dB, however can be
reduced –3dB to create a smoother transition between the midrange and
tweeter. The ability to level match allows the system to be custom “tuned”
for a particular listener or setup.
THE RESULT: Allows custom setup of tweeter output level.
