Enclosure Compatibility
Features
Infused Kevlar and
Crystalline Oxide Fiber Cone with Polypropylene Coating: Extremely rigid and
strong with exceptionally fast transient performance for tight natural sounding
bass and low distortion even at high power levels.
Natural Butyl Rubber Surround:
Outstanding
linearity under hard drive/high power applications. Long throw with minimum cone
drift results in wide dynamic range and low distortion. Resists ultraviolet
radiation.
Nomex(TM)
Spider Material: Vastly
stronger than conventional cloth. Resists tearing or warping under high power
conditions for improved long-term reliability.
Deep Draw Diecast Frame: More
rigid than stamped steel so frame distortion and resonances are effectively
eliminated. Nonmagnetic so all the magnetic energy is used to tightly control
the diaphragm for increased output with prolonged reliability. High efficiency
combines with excellent transient response and acoustic definition.
Proprietary Integrated Dust Dome:
Dust
dome is designed as a structural member of the cone body for greater cone
integrity. Lower distortion even under extreme loading conditions.
Unitized Magnetic Circuit: Monolithic
pole piece/back plate construction for maximum magnetic efficiency.
Oversized Voice Coils:
Handcrafted 3″ voice coils wound with precision Swiss wire for high power
handling. Consistent and outstanding performance over the long-term.
High Energy Strontium Ferrite
Magnet: Intense flux density with greater than a 10% increase over
conventional strontium ferrite magnetic materials for high efficiency and
greater control with fast transient response.
Deep Groove Backplate: Extended
voice coil excursion capability for increased mechanical power handling
resulting in enhanced reliability as well as higher output.
Vented Pole: Effectively
transfers heat away from voice coil for improved thermal power handling and
reliability.
Enclosure:
This woofer is designed for mounting in a small sealed enclosure, which will
provide the most accurate bass response. When used with a subsonic filter
(25-35Hz/12dB per octave) it can also be mounted in a ported enclosure (please
see the “Enclosure Compatibility” section for more information on the
recommended enclosures).
Enclosure
Compatibility
Recommended Sealed Box
Volume: 2.25 cu/ft (enclosure loosely filled with poly-fill) or 2.75 cu/ft (enclosure not filled with poly-fill)
Recommended Vented
Box Volume: 3.93 cu/ft with 4″ diameter and 11.69″ long port
(tuning frequency of 35Hz)
Note:
The specifications listed with the vented enclosure
recommendations assume a subsonic filter (sold
separately) between 25Hz and 35Hz with a slope of 12dB/octave is used with this
woofer. If a subsonic filter is not used, the
power rating will decrease and excessive port noise can occur.
