Kurt, Avalon specifies "26Hz to 34kHz (+/- 1.5 dB, anechoic)." I forget which is lower anechoic or in room. My Eidolons measured 32Hz just a hair below 0dB at the listening position using Velodyne Manual Room Optimization in my room with the spikes on metal wood floor protectors. I use the room in thirds as location for placement and listening position.
I use two irregularly positioned Velodyne DD-12 Plus subwoofers with the first two EQ presets set flat with one in and one out of phase. The remaining presets are slightly altered and the last is set for radical Rap bass. With all this flexibility at the push of a button I mute the subs for quite a few LPs that simply sound right without the subs yet almost never for digital playback.
I recall hearing a pair of Andra's being driven by a VTL S80? and a VTL pre. in a store in Palo Alto on the El Camino long ago. Wow! You did good.
Enjoy
