BP-10 | Alumapro 10 inch 400 watt Band Pass Enclosure

Maximum Bass in Minimum Space — Hand-Built in Huntley, IL

The BP-10 is the sweet spot of the BP-Series — a 10" bandpass enclosure that delivers deep, powerful bass without taking over your entire trunk. Alumapro's dual chamber bandpass design is more efficient than conventional sealed or vented enclosures, so it hits harder with less amplifier power. Frequency response reaches down to 20Hz, putting out the kind of low-end that you don't just hear — you feel.

Dual Chamber Bandpass Design

The BP-10's precisely tuned dual chamber system harnesses both the front and rear energy of the woofer simultaneously. The result is significantly higher efficiency and SPL from a mid-size package that outperforms subwoofers rated at much higher power. The frequency response is specifically shaped to complement car cabin acoustics, delivering tight, musical bass that extends well below 30Hz.

Alumapro Aluminum Alloy Cone Woofer

Inside the BP-10 is a dedicated 10" Alumapro woofer featuring the signature aluminum alloy cone — immune to temperature and humidity extremes that destroy paper and poly cones. The massive motor structure, rigid frame, Kevlar spider, and Santoprene surround are built for sustained high-output performance without compromise.

Aero-Port Technology

Large flared aero-ports eliminate compression and port noise that plague lesser enclosures. At high output levels where cheap boxes start choking and making wind noise, the BP-10 stays clean and composed. More air moves freely, more bass reaches your ears.

Built to Last, Built to Impress

Premium durable black carpet, heavy-duty bolted and clamped construction, and a thick gasketed plexi viewing window with carbon-pattern accents. The BP-10 looks as serious as it sounds. Show it off — it deserves to be seen.
