Polyglass Cone: The woofer cone has a cellulose pulp base
and is coated with a uniform deposit of hollow glass microballs. The addition of
the Polyglass layer significantly increases the cone's rigidity without adding
much weight. This combination takes advantage of the accuracy and neutrality of
the hard outer surface, but maintains the superior damping characteristics of
the cellulose pulp.
Surround: The butyl rubber surround is resistant to ultraviolet
rays, temperature extremes, and humidity to add to the speaker's reliability
Phase Plug: The bullet-shaped phase plug in the center
of the woofer ensures a smooth, flat off-axis frequency response by preventing the
high frequency sound waves emanating from one side of the cone from interfering with
sound waves from the other side of the cone.
Aluminum Basket: The woofer features a non-magnetic cast aluminum
Inverted Dome Tweeter: The tweeter is an inverted aluminum
dome, producing a broad sound stage. The tweeter has a Neodymium magnet to provide
a powerful magnetic field for the voice coil, while still maintaining the tweeter's
Mounting Options: The tweeters include two types of surface
mount housings, one low profile and one angled:
| ||Flush Mount ||Low Profile Surface Mount ||Angled Surface Mount |
|Mounting Height ||0.292" ||0.898" ||1.948" |
|Mounting Depth ||0.511" ||0.875" (screw depth) ||0.875" (screw depth) |
|Frame Diameter ||1.886" ||N/A ||N/A |
|Cutout Diameter ||1.677" ||N/A ||N/A |
|Width ||N/A ||1.887" ||1.894" |
|Surface Depth ||N/A ||1.887" ||2.865" |
Crossovers: Individual crossovers are included for each woofer
and each tweeter. The crossovers can be mounted separately, docked in pairs, or all
four crossovers docked together and mounted as one unit. The crossover inputs and
outputs are screw terminals and will accept bare wire or spade connectors up to
0.31" wide. Because the woofer and tweeter crossovers are separate, and have
separate inputs, the system can be bi-amped. The woofer crossover point is 3.5
kHz, all the crossover slopes are 6 dB/octave, and the tweeter crossovers offer
- Tweeter Attenuation: set the tweeter
output to -3dB, -6dB, or 0dB (no attenuation)
- Tweeter Crossover Point: the tweeter
crossovers also offer three crossover point options; 4 kHz,
4.5 kHz, and 5 kHz
- Length: 4"
- Height: 1-1/4"
- Individual: 2"
- Pair: 4"
- All four: 8"
