B2 Audio Subwoofer Box Plans – Engineered Enclosures for Extreme Output and Elite Performance
B2 Audio subs are built for enthusiasts who demand more—more power, more control, and more pressure. These B2‑specific subwoofer box plans are engineered to match that philosophy. Every enclosure is tuned to the exact airspace, port area, and mechanical behavior each B2 series is designed for, giving you deeper lows, cleaner response, and harder‑hitting output across the entire lineup.
Whether you’re building a clean daily setup, a street‑loud system, or a full‑blown competition vehicle, these plans give you the blueprint to get the most out of your B2 drivers. From the budget‑friendly Riot Series to the aggressive Rage and Rage XL lines, all the way up to the competition‑ready Rampage and X2 monsters, each enclosure is dialed to match B2 Audio’s high‑output performance profile—so your system hits harder, plays lower, and stays reliable under extreme pressure.

Riot Series – Affordable, Clean Bass for Daily Systems
The B2 Audio Riot Series delivers reliable daily performance with smooth low‑end response and modest power handling. With RMS ratings around 750W and common sizes like 12–15 inches, these subs are ideal for beginners and budget builds that still want real output. Riot‑optimized box plans focus on efficiency and compact airspace, giving you clean bass, strong low‑end extension, and dependable performance in small to mid‑sized enclosures.
Rage Series – Stronger Motors, Bigger Output, Better Control
Stepping up from the Riot line, the B2 Audio Rage Series brings more motor force, higher RMS power (around 2000W), and tighter suspension for noticeably stronger output. Available in multiple sizes and coil configurations, Rage subs shine in well‑designed ported boxes where airflow and tuning can take advantage of their increased capability. Perfect for daily drivers who want deeper lows, more punch, and a more authoritative sound without jumping into extreme SPL territory.
Rage XL Series – High‑Performance Daily/SPL‑Leaning Output
The Rage XL Series pushes into high‑performance daily and entry‑level SPL territory. With RMS ratings around 3500W and heavy‑duty carbon‑fiber cone assemblies, these subs offer clean, powerful bass with excellent bandwidth and control at high volume. Rage XL‑specific box plans emphasize low‑end extension, port efficiency, and structural rigidity—ideal for builders who want musicality with serious output and the ability to get loud when needed.
Rampage Series – Competition‑Ready Power and Aggressive Output
The B2 Audio Rampage Series is built for high‑power street setups and competition‑leaning builds. With RMS ratings around 1000W for the smaller models and extremely efficient motor structures, these subs are engineered for aggressive output, heavy excursion, and high‑pressure environments. Rampage‑optimized enclosures use large ports, reinforced bracing, and airflow‑efficient layouts to keep the sub stable under brutal power. Ideal for demo builds, SPL‑leaning daily systems, and anyone chasing serious loudness.
X2 Series – Maximum Strength, Maximum Pressure, Maximum Output
The X2 Series represents B2 Audio’s top‑tier, extreme‑output subwoofers—designed for SPL competitors, demo vehicles, and high‑voltage, high‑power applications. With RMS ratings reaching up to 10,000W on massive models like the X2SIX 33", these subs feature oversized motors, ultra‑stiff suspensions, and reinforced structural components throughout. X2‑specific box plans are engineered to handle violent air movement, huge port area, and the mechanical force these monsters generate. Perfect for hardcore competitors and demo enthusiasts who need maximum durability and output.
