Ron, when you auditioned the Pendragons, was their output augmented by subwoofers?
No, there are no subwoofers at Gryphon Audio. It never would have occurred to me to even consider subwoofers, as the eight 8” drivers of the Pendragon woofer tower have the same surface area as two and one-quarter 15” drivers.
But then I heard MikeL’s four 15” drivers X 2, Audioquattr’s 16” + 16” + 18” drivers X 2, and a friend’s RELs on top of subwoofer towers, and until I read about Arnie’s (in Texas) dual subwoofers with Rockport Arrakis, and Wilson Master Chronosonics with Master Subsonics.
The closet analogue (no pun intended) would be a friend’s RELs on top of subwoofer towers. The RELs provided a kind of low frequency foundation to the whole sound-stage that I found desirable. Interestingly, this friend’s room, like my room, has large openings on each side wall. I theorize that a listening room with large openings results in the room having a different ability to absorb (and release) low frequency information than is the case with a sealed room.
Similar to the way it turns out that there is phase information above 18 kHz which we don’t hear directly but somehow perceive (per Sean Casey), I think there is infrasonic information below 20 Hz which we might not hear directly but which somehow contributes to a more believable sonic experience.
MikeL may be able to elaborate on this, as his system is down like only -3dB at 10 Hz, or something wild like that.
