Klipsch Heresy IV owners? what amp are you running

great story!

@audiocanada 

Heresy IVs on their risers with their backs as close to the wall as possible and aimed at the listening position will easily go down to 40Hz. Power from tube amps is not an issue, my 3 watts per channel Luxman SQ-N150 could drive them as loud as I could want and my 6 watts per channel Luxman LX-380 drove them beautifully as well. Just remember that most music has very little information anywhere near 40Hz and the room and boundary reinforcement from your walls will help extend the bass to that frequency if there is any in the program.

McIntosh Mc240 - I also run a pair of REL subs. Magical combo. Subs and most Klipsch are friends. 

@decooney Regardless of the component in question any account of someone’s getting off the Merry-Go-Round makes for an interesting read. Thanks for sharing, nicely done. 
 

As of now, I go back and forth using a MC252 and an Anthem STR, always with SVS subs. Lately it seems the STR stays in most of the time and the MC252 is powering my Khorns. "Subs and most Klipsch are friends". Truer words my friend.
