Need help?Do you have a question about the AudioBahn ALUM12Q and is the answer not in the manual?
Continuous exposure to sound pressure levels over 100 dB may cause permanent hearing loss. Use common sense.
Dual voice coil woofers use a polished chrome aluminum cast basket for alignment and rigidity.
Offers stability, strength, and high output without cone failure and lowers distortion.
Anodized aluminum former for efficient thermal transfer and improved power handling.
Provides a more linear magnetic field, lowering distortion and improving low frequency response.
Allows more excursion and higher power handling by circulating cool air around the voice coil.
4-layer, edge wound voice coil design for various impedance loads; dual 6 ohm configuration.
1.75" EPDM surround is resilient to temperature variations, improving clarity and frequency response.
Provides symmetrical control of the voice coil for reduced harmonic distortion and better sound quality.
Durable, protective metal finish that is also a great addition to any enclosure.

Recommendations for constructing a rigid enclosure using MDF and internal bracing.
Formula and method for calculating box volume in cubic feet, accounting for material thickness and displacement.
Explanation of passive vs. active crossovers and recommendation for an active 80-100Hz low pass crossover.
Verify connections from amplifier/processor to box and inside the box for loose wires.
Check enclosure for leaks, cracks, or broken pieces that could cause performance loss or distortion.
Remove subs to check for burned wire leads or separated components; smell for burning.
If issues persist, check connections to amplifier, source unit, or other processors.
Investigate layout before drilling, take care near lines, and secure system to prevent damage.
Fuse +12V DC power wire at battery, disconnect battery before connections, use identical fuses.
