Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
IMPP Cone: The Pioneer TS-W254R features an IMPP (Injection
Molded Polypropylene) woofer cone. This process of cone molding assures a uniform
cone thickness for superior linearity and clarity.
Voice Coil: The woofer's 6-layer, long voice coil design allows
expanded piston motion for better linearity, improved power handling, and more bass
Extended Pole Yoke: The extended pole yoke expands the magnetic
field, improving linearity during large woofer excursions.
Vented Pole Yoke: The vented pole yoke allows air circulation
within the motor structure to ensure better heat dissipation, thus improving the
power handling capacity.
Terminals: The heavy duty spring compression terminals will
accept pin connectors, single banana plugs, and bare wire up to 10 gauge.
Enclosure Compatibility: The Pioneer TS-W254R offers great
performance using either a sealed, ported, or bandpass enclosure.
Sealed Box Volume: The sealed box sizes recommended by Pioneer
range from 0.65 cu/ft to 1.25 cu/ft. Within this range, the ideal recommended size
is 0.8 cu/ft.
Vented Box Volume: The vented box sizes recommended by Pioneer
range from 0.9 cu/ft to 1.5 cu/ft. Within this range, the ideal recommended size
is 1.1 cu/ft. The recommended port diameter is 3" and the length varies with
enclosure size; 7.5" long with the 1.1 cu/ft enclosure, 8.5" long with the
0.9 cu/ft enclosure, and 6" long with the 1.5 cu/ft enclosure.
Bandpass Volume: The bandpass box sizes recommended by Pioneer
range from 0.45 cu/ft to 0.8 cu/ft (per chamber). The ideal enclosure has a 0.6 cu/ft
sealed rear chamber and a 0.6 cu/ft ported front chamber. The minimum recommended
size has a 0.45 cu/ft sealed rear chamber and a 0.45 cu/ft ported front chamber. The
maximum recommended size has a 0.8 cu/ft sealed rear chamber and a 0.8 cu/ft ported
front chamber. The recommended port diameter is 3" and the length varies with
enclosure size; 5.5" long with the 1.2 cu/ft enclosure, 6" long with the
0.9 cu/ft enclosure, and 5" long with the 1.6 cu/ft enclosure.
