About the Alpine PLT-5
LAT Subwoofer System

Revolutionary technology, massive sound, and Alpine — they just go together. Alpine's LAT Subwoofer Systems utilize cutting-edge Linear Array Transducer (LAT) technology, which uses a series of small woofers to create sound output equal to that of a much larger subwoofer — while using much less space.

Revolutionary technology, massive sound, and Alpine — they just go together. Alpine's LAT Subwoofer Systems utilize cutting-edge Linear Array Transducer (LAT) technology, which uses a series of small woofers to create sound output equal to that of a much larger subwoofer — while using much less space.

The PLT-5 Subwoofer System's subwoofer array consists of six 5-inch cones that provide the same bass punch as a pair of 10" subs. Alpine houses the subs in a super-efficient Ultra Reflex enclosure and matches them up to a highly-efficient 250-watt digital amplifier. The result? Clean, pounding bass from an enclosure that will fit behind the front seat of most full-size regular cab pickups.

The PLT-5 incorporates speaker- and preamp-level inputs, and features a low-frequency filter for matching the bass output to your system. A remote bass knob gives you fingertip control of the variable bass boost.

Features

Product Overview: The PLT-5 features Linear Array Transducer (LAT) technology, which uses a series of small woofers to create sound output equal to that of a much larger subwoofer. The subwoofer array consists of six 5-inch cones that provide the same bass punch as a pair of 10" subs. The woofers are housed in a small Ultra Reflex enclosure and powered by a 250-watt RMS amplifier.

Low-pass Filter: The built-in low-pass filter can be adjusted from 50 to 120 Hz.

Bass Boost: The amplifier features a 0 to +12dB bass boost, centered at 45 Hz.

Remote Bass Control Knob: You can control the bass level from the driver's seat with the supplied Remote Bass Control knob. The control knob connects to the amplified subwoofer via the supplied remote bass cable. The control knob has the following dimensions: W=1.794" (including mounting flanges), H=1.008", D=2.352" (including knob).

Phase Control: The subwoofer's phase control allows you to adjust the phase of the subwoofer's output relative to the system. If the bass sounds muddy or unclear, adjusting the phase control can sometimes strengthen the bass "attack."
