    Per the title... I have four Stereo Integrity HT 18 D4 for IB install via two manifolds. How much RMS power can each driver "safely" handle (using both voice coils)? Estimates are okay! OR...

    It looks like Roxul Safe n Sound is only available in Canada. What is a comparable product in the US? Or is 'pink stuff' with double drywall good enough. This is for a basement HT. Thanks.
