  • 10” 4 Subwoofer
  • Power Handling: 250W – 750W
  • Progressive Wavelet Ribs (P.W.R.) Cone Design
  • High Strength Custom Steel Frame
  • Great complement to V-Power Mono Amplifiers

The New Standard In Its Class

  • These subwoofers make a statement with their bold new cosmetic look. The dust cap features a BASSLINE logo printed in matte silver, and there’s a raised Alpine logo on the trim ring.

P.W.R.™ Cone Design

  • The SWA’s patent-pending Progressive Wavelet Ribs (P.W.R.) cone design helps break up standing waves and cone resonances to keep distortion low and musical enjoyment high.

Leading the Class With Output

  • Get the bass you can not only hear, but also feel. Through its optimized suspension design and new cone materials, this subwoofer allows over 52mm peak-to-peak cone travel.

Polypropylene and Mica Damped Cone Assembly, with Poly-Foam Surround

  • BASSLINE subwoofers use a polypropylene and mica damped cone assembly, which keeps the cone stiff and light for great sounding bass tones. The high-excursion poly-foam surround provides high output bass.

Progressive Polyester Spider

  • The progressive polyester spider provides accurate control of the subwoofer cone.

Two-Piece Yoke

  • The two-piece yoke uses a vented pole, to provide improved air flow and help with the cooling of the voice coil.

High Strength Steel Frame

  • With such a highly efficient airflow system we have incorporated a custom shaped high strength steel frame to help keep woofer performance accurate.

8-Gauge Push Terminals

  • Keeping power consistent to your subwoofers is just as important as keeping them cool. The BASSLINE subwoofers use 8-gauge push terminals for easy connection to speaker wires.

Easy System Building with V-Power Amplifiers

  • BASSLINE subwoofers make a great match with V-Power amplifiers. The amplifiers are known for their reliability, small size and big power output. When used with the BASSLINE subwoofers, you get a strong sound system at a friendly price. BASSLINE subwoofers and V-Power amplifiers can even be added to a factory radio, to provide an easy and impactful bass boost to the existing sound system.
