"It's Heresy man." I’m a kick drum tone freak to the extent that I’ve required therapy for this from time to time, and my band opened for Led Zeppelin in early ’69, a thing that takes years to recover from if you’re a Bonham fan. I’ve also jammed with Mitch Mitchell (in town for a Hendrix show also in ’69) which made most other drummers seem...well...inadequate). In any case, after decades of being a kick drum aficionado (and working as a musician and sound engineer), my recently acquired Heresy IIIs seem to provide a surprisingly great sounding kick drum experience. You do need a sub or two with these speakers as they’re very accurate down to only 58hz or so, and 2 RELs are in service for that task in my rig. Also, recent recordings of Julian Lage with Kenny Wollesen (mixed a show of theirs a couple of years ago) provides some kick therapy. Jim Campilongo's band...oh yeah...uh huh...
