What Makes the R3-8 a Standout Performer?

Designed for Tight Installs — Without Sacrificing Output

In today’s vehicle builds, space is a premium. But with the R3-8’s shallow-friendly design and smart motor engineering, you can pack deep, punchy bass into enclosures where most full-size subs won’t fit. It perfectly matches compact cars, trucks, and stealth installs.

Dual 2 Ohm Voice Coils for Flexible Wiring Options

The dual voice coil (DVC) configuration makes pairing the R3-8 with various amplifiers and wiring schemes easier. Depending on your system's needs, you can wire it in series or parallel. For help, check out the Subwoofer Wiring Diagram to ensure your amp setup matches your impedance goals.

Built Tough — Fiberglass & Epoxy Cone Design

The R3-8 isn’t just strong—it’s engineered to last under pressure. The cone is constructed using fiberglass stranding woven and bonded with epoxy over a pulp backing. This unique material blend delivers rigidity with a natural resonance, ensuring minimal distortion and maximum punch at high volumes.

High-Excursion & Low Distortion

Thanks to a high roll surround and extended excursion design, the R3-8 moves serious air for an 8-inch woofer. That means you get more bass output per watt and less cone breakup—even at extreme volumes. It’s an SPL-friendly and SQ-focused solution, giving you the best of both worlds.

Why Choose the Soundstream R3-8?

If you’re looking for a compact 8-inch subwoofer that performs like a larger driver without taking up space, the R3-8 is the answer. It blends build quality, advanced materials, and flexibility in a way few subwoofers can match.

Whether you run it solo or pair multiple R3-8 subs, it delivers high-output performance with low distortion. And if you're a Soundstream loyalist, it's a seamless match with the Soundstream Tarantula XP amplifier or Rubicon Nano series.
