Citing the type of application and music preferences you have indicated, if you are truly looking for that extra lower octave O -O - M - P - H as you have stated, do yourself a favor and look seriously at the entire lineup of REL subs. For dynamic audio reproduction or that extra "kick" you seem to lack, REL will provide exactly what you are looking. You can also contact one of their audio specialists and describe your interests and equipment setups and they will recommend the exact model that will offer the greatest reward. You might even consider a balanced pair.
Just be certain you have the amplifier connectivity to set up the sub(s) at a "high level" (speaker level) connection. This should be no problem with the equipment you have indicated. REL will walk you through the proper way to connect and integrate seamlessly into your system.
