## Overview

The Pioneer TS-WH500A is a groundbreaking compact active subwoofer featuring 150W max power MOSFET amplification and patented HVT technology. Its ultra-slim design (just 2.4 inches deep) fits easily under car seats, delivering rich, distortion-free bass through a dual motor bipolar woofer system. Perfect for professionals and audiophiles seeking premium sound without sacrificing space, it includes all necessary wiring for quick installation and long-lasting performance.

## Description

HVT stands for Horizontal Vertical Transforming technology which transforms horizontal movement of a voice coil into vertical movement of a woofer diaphragm to produce true, powerful and wide-range bass in a very shallow, reduced depth structure. The TS-WH500A amplified subwoofer system is a truly groundbreaking approach in loudspeaker design. HVT technology uses a unique linkage mechanism, which allows the magnet and voice coil of the dual motor structure to be positioned horizontally to the left and the right side of vertically moving dual speaker diaphragms. Combined, the two diaphragms have an effective surface area equal to a conventional 8" subwoofer and fire in a bipolar arrangement, increasing output while also canceling destructive vibrations within the enclosure. The result of this innovative technology is a subwoofer system with significantly reduced physical depth, while maintaining greater excursion and linearity for superior bass reproduction, natural sound quality and higher output.

## Features

- Built-in 150 W Max (50 W RMS) MOSFET amplifier
- 7-1/8" x 3-7/8" Rectangular HVT (Horizontal Vertical Transforming) Dual Motor Bipolar Subwoofer (8-1/4" woofer effective surface area)
