The PRO-X woofers were designed for Team Interfire Members

The Pro-X series subwoofers are the long awaited Monster woofer. Interfire has designed the Pro-X woofers with the perfect balance of Sound Quality and SPL to extract the maximum performance with clear audiophile accuracy.

A perfect combination of brutal bass
with audiophile accuracy.

All in all, the IFG series subs provide clean, accurate bass.
