About The Product
The Champion Series subwoofers have evolved from Pioneer’s award-winning “SPL Champion Edition” lineup, known for its deep and powerful bass production. The TS-A301S4 12” dual-voice coil subwoofer features a redesigned large and powerful 90 oz double-stack magnet for improved efficiency and sensitivity. The subwoofer baskets are optimized with a reinforced structure design for added strength and reduced vibration, delivering excellent sound quality. This subwoofer has a continuous power of 500 watts with a maximum peak of 1,600 watts. It features an advanced 2-piece cone designed with a highly rigid and durable Honeycomb IMPP™ composite cone structure, plus a rigid drive cone to deliver high output levels with reduced distortion.
Iconic Champion Series Cosmetics
The Champion Series Subwoofers features iconic design elements that are symbolic to the subwoofer’s lineage including red graphics design decals; spider; and “Champion” cursive script.
Advanced 2-Piece Cone
Designed with a highly rigid and durable Honeycomb IMPP™ composite seamless cone plus a rigid drive cone for deeper and louder bass reproduction.
Dual Layer Surround
A lighter and more durable surround, this subwoofer is comprised of elastic polymer and reinforced fiber to support the woofer during cone excursion for accurate and powerful bass.
Deep Bass
To achieve deep and tight bass, a rigid and lightweight cone is essential. However, without a proper motor structure, it’s ineffective if you’re looking for strong and dynamic bass. The subwoofer uses a double-stack strontium magnet for a stronger and longer magnetic field, paired with a large copper voice coil and an aluminum voice-coil former for better bass control under high excursions. This also helps achieve better heat dissipation.
Reinforced Steel Basket
This Champion subwoofer features a reinforced steel chassis with a grooved structure that increases strength through stress dispersion. This robust design, intended to support high driving power, also helps minimize any vibrations that may be induced during large cone excursions. The goal is to give you only the good vibrations that are on the recording.
