I think I will go lol
Heard a lot of really good sounding systems the first day of RMAF, and then I entered the Von Schweikert room, and had a transcendental Out of Body Experience. I've never heard of an audio system sound this close to live music before in my life.

Did I get to meet you?
Haven't found much yet online about the VSA room but if you locate any links, share them here. Here's one pic:https://theaudiobeatnik.com/rmaf-2018-pictures-day-2-part-1/
Leif runs the sub out of phase to reduce/eliminate bass boom.
KLH007, the VSA subwoofers don't have a phase switch. They have a phase rotation dial. It's important that the amount of phase rotation is correct based on the distance of the subwoofer(s) from the front speakers. When dialed-in, the system cancels room nodes, eliminating peaks and troughs due to room interactions. Basically, at the correct phase rotation setting, the front speakers and the rear subs interact to provide flat response.I'm using a pair of the XS-15 subwoofers at the back of my listening room as part of the VR100XS system. The subs are located 45 feet from the front of the VR100 towers, 52 feet from the front wall. The phase rotation is set to 170 degrees for that distance. With well recorded live performances the system extends the soundstage into and through my listening room, replacing my room's acoustics with the spatial qualities of the recording venue (surprisingly, including height). One VSA subwoofer does a good job at taming room nodes. However, to most fully recreate the left/right components of the venue's acoustics and to open up the height, you'll want two of the VSA subs, one driven by each of the left and right main speakers (I've done the comparison).These aren't simply subwoofers. They're a key component in an integrated system capable of recreating a performance's acoustic space. Think of it as aural holography.Best,Robert
