Frequently Asked Questions

What makes the AudioControl SPK-12S2 a high-performance subwoofer?

The SPK-12S2 features exceptional 14mm linear excursion, advanced fiber matrix paper cone with mica coating, dual damping system, and 500W RMS power handling capability, delivering ultra-low bass extension and superior performance with enhanced output from the larger 12" driver.

How does the 14mm linear excursion benefit bass performance?

The exceptional 14mm Xmax allows the subwoofer to move significantly more air than typical drivers, resulting in deeper bass extension, higher output levels, and more impactful low-frequency reproduction for an immersive listening experience.

What amplifier power range works best with the SPK-12S2?

The subwoofer performs optimally with amplifiers delivering 300-700W RMS at 2 ohms, with 500W RMS being the ideal power level for maximum performance and longevity while maintaining clean bass reproduction. The 2-ohm configuration provides efficient power transfer.

How does the dual damping system improve performance?

The dual damping system provides superior cone control and linear bass reproduction by eliminating unwanted resonances and maintaining accurate response across all frequency ranges and power levels.

What enclosure type provides the best performance for the SPK-12S2?

For maximum bass extension, a ported enclosure (1.77 ft³ tuned to 39 Hz) provides F3 response to 30 Hz. For tighter, more controlled bass, a sealed enclosure (1.0 ft³) offers excellent performance with F3 response to 53 Hz.

How does the 12" driver compare to smaller Spike Series models?

The SPK-12S2 provides enhanced bass output and improved low-frequency extension compared to smaller Spike Series models. The larger cone area delivers more air movement for deeper, more impactful bass while maintaining the same advanced features and build quality.
