Pioneer TS-W1001C - Manual (Page 6)

• DESIGNED FOR ENCLOSURE USE
C and DVC series subwoofers are designed to provide optimum bass performance when used in a speaker
enclosure with appropriate internal volume. If the internal volume of the enclosure is smaller than the
recommended size, the speaker will not be able to reproduce frequencies as low as that of the recommended
enclosure. If the internal volume of the enclosure is larger than what is recommended, it will adversely affect the
frequency response characteristics and performance of the speaker. This is commonly referred to as under­
damped alignment. Over excursion of the subwoofer may result. PIONEER recommends the speaker enclosure be
manufactured with 3/4" MDF particle board. Always glue and screw the enclosure together to ensure it is correctly
sealed.
Whenever possible seal all edges with silicone caulking as well. PIONEER recommends
that the inner wall of the enclosure be covered with a sound-absorbing material to provide better sound quality. These
suggestions should be followed when building a ported enclosure as well.
If this product is used in free-air conditions (without an enclosure), insufficient damping causes the
sound without accuracy and reduces the power handling capability to 1/4 of its usual levels. It may
result in permanent damage to the product.
• FEATURES
1 METAL-COATED FOAMED IMPP CONE WITH ALUMINUM INSERT, with its light weight and high
rigidity, reproduces pure and vivid sound in bass frequencies.
2. VCCS (Voice Coil Cooling System) reduces voice coil heat allowing for stabler bass reproduction and
reinforced power handling capability.
3. LEAD WIRE INCORPORATED LARGE DIAMETER CONEX DAMPER makes possible powerful
reproduction of deep bass with high linearity.
4 LARGE STRONTIUM MAGNET allows powerful drivability and higher efficiency to reproduce well-damped,
tight bass.
5 4-LAYER LONG VOICE COIL DESIGN allows powerful drivability and improves linearity at high input levels.
6 EXTENDED POLE YOKE, with its ability to expand the magnetic field greatly improves linearity during large
excursions at high input levels.
7 VENTED POLE YOKE allows better heat dissipation to improve power handling capabilities.
8 LONG STROKE MAGNETIC CIRCUITRY is designed for input resistance to achieve larger excursion
linearity.
9 BEST TUNED PARAMETERS from computer simulation help, provide rich bass response with superb
resolution.
