Audiopipe 15 Quad Stack Composite Cone Subwoofer (TXX-BDC-IV-15D2), Superior Performance, 2800W, 4 Magnets, BASV Voice Coil, Aluminum Basket, Weaved

The Audiopipe 12 Quad Stack Composite Cone Subwoofer is marketed as a powerful and well-built option for car audio enthusiasts. However, some users have reported initial challenges with the stiffness of the foam surround, which they believe needs a break-in period of a couple of weeks to perform optimally. One user mentioned experiencing overheating issues with both the subwoofer and amplifier, suggesting that the stiff surround may have caused performance problems. This resulted in a limited frequency response, with significant bass at 60 Hz and below, which suited certain music genres but struggled with others such as house music with varying bass frequencies. Despite these challenges, some users still appreciated the subwoofer's power and performance, noting that it delivered hard-hitting bass as advertised. However, the lack of break-in instructions and detailed frequency response graphs on the Audiopipe website left some users feeling uncertain about optimizing their setup for the best sound quality. In conclusion, the Audiopipe 12 Quad Stack Composite Cone Subwoofer offers a solid build and powerful performance once properly broken in, but users may need to experiment with amplifier settings to achieve the desired sound quality across different music genres. **
