Woofer: The TS-W1208D2 is an IMPP (Injection Molded Polypropylene)
composite cone woofer with interlaced Basalt and Aramid fibers. This process of cone
molding assures a uniform cone thickness for superior linearity and clarity. The cone
is lightweight and rigid for low distortion and superior bass response.
3-Layer Urethane Surround: The surround uses two layers of urethane
with a layer of interwoven fiber between them to add strength and stability and reduce
Dual Voice Coils: For increased system flexibility, the
woofer has two 2Ω voice coils. The two sets of spring compression binding post
terminals are side-by-side for easy wiring. Each post will accept a pin
connector, a single banana plug, or bare wire up to 10 gauge. The speaker is
shipped with two of the terminals shorted together and covered (wired in series)
to present a 4Ω load. Remove the shorting wire and connect the terminals in
parallel to present a 1Ω load. Additionally, each coil can be connected to a
different amplifier channel and each channel will see a 2Ω load.
Dual Mass Magnet: The TS-W1208D2 uses a Dual Mass Magnet assembly
(weighing in at 83oz.) to create a powerful magnetic force. This increases the control
exerted over the voice coil and the power transferred to the cone.
Sealed Box Volume: The sealed box sizes recommended by Pioneer
range from 0.85 ft³ to 1.75 ft³; within this range the ideal size is 1.25 ft³.
Vented Box Volume: The vented box sizes recommended by Pioneer
range from 1.25 ft³ to 2.05 ft³; within this range the ideal size is 1.65 ft³. The
ideal port size for a 1.65 ft³ enclosure is 3" diameter x 6" long.
Single Reflex Bandpass Volume: The bandpass box sizes recommended
by Pioneer range from 0.7 ft³ per chamber to 1.1 ft³ per chamber; within this range
the ideal size is 0.9 ft³ per chamber. One 3" diameter x 3.5" long port
should be used in an enclosure with 0.9 ft³ chambers.
Power Handling: The woofer has two 2Ω voice coils; each
coil can handle up to 200 watts RMS (400 watts total).
Warranty Note: The included warranty card indicates a 1 year
parts and labor warranty for Premier brand loudspeakers. The warranty is extended
to 3 years if the speakers are installed by a Pioneer Premier dealer. However,
Pioneer has extended the warranty to 3 years for all Premier brand speakers purchased
from Crutchfield, regardless of who installs them.
