Voice Coil and
Motor System:
25mm
Complimentary
design.
The voice coil used in the I6 midbass is a 2-layer aluminized copper wire
coils on a round former. An “overhung” voice coil was selected to improve
sensitivity while still keeping distortion to a minimum.
Tweeter Speakers (Imagine I1)
Dome:
Small
diameter
impregnated silk
textile dome with
high-loss rubber
suspension.
The I1 has an impregnated fine cloth silk dome diaphragm for a linear,
smooth sound, with a high-loss rubber suspension to damp edge modes and
resonances. The dome is of extremely low mass and is much less
susceptible to mechanical deformation than other designs, and yet yields a
smooth response over the extent of its range. At Hybrid Audio Technologies,
we feel larger diaphragm tweeters sound heavy and unremarkable, lack
detail in the upper treble frequencies, have undesirable polar response, and
are difficult to install. Additionally, we find metal dome tweeters to be harsh,
brittle, and sound unrealistic. As a small diameter, soft-dome tweeter, the I1
is the antithesis of large diaphragm and metal-dome tweeters, for the
effective and convincing reproduction of treble frequencies.
Voice Coil and
Motor System:
25mm
Complimentary
design.
The motor assembly is “conventional dynamic”, with a compact neodymium
magnet structure to ensure a small footprint size and shallow depth. A
perforated grille protects the dome. The voice coil is ferrofluid cooled and
damped, and the tweeter housing consists of extruded plastic with three
different mounting options in component set mode, giving the end-user
flexibility in not only placement of the I1 but also in physical installation.
Tweeter Passive
Crossover:
Low-
Tolerance Mylar
Capacitor
The tweeter’s protection circuit and crossover filter is a very high-quality,
low-tolerance Mylar capacitor that has been affixed to the midbass frame.
The set ships as a coaxial set, and is ready to install. Should the end-user
want to connect the tweeter in component set mode, simply unscrew the
tweeter, remotely mount the tweeter, and extend wiring back to the midbass
terminals for re-connection to the tweeter output posts. Refer to Page 10
for more details on how to convert from coaxial to component set.
