Gateway is a John Storyk design. D'Antonio provided the Difractal rear wall.
Since then, they worked together in every recording studio WSDG did.

I might clarify a couple of points. Storyk and RPG indeed have a close relationship. Though Dr. D'Antonio doesn't have a hand in the nuts and bolts of Storyk's designs, his products, ideas, and information certainly have an influence on John's work. Our SSL room is a recent example of a Storyk studio.

Gateway was somewhat unique in that D'Antonio took a more active role in the design of Bob's studio beyond simply the design and supply of diffusors. He did indeed custom design the three-band diffractal in back, and provide flutterfree for the ceiling, and BAD panels (thin non-QRD diffusors) for the side walls, but that's not all.

Storyk has clearly provided architectural and design services for Gateway, though I don't recall at the moment the specifics of who did what and when. Bob Ludwig's own words offer some insight to D'Antonio's involvement in the original mastering room, beyond supply of RPG products. Storyk's name didn't show up in this particular discussion, though I don't know why.

To quote Bob:

"Together, with Dr. Peter d'Antonio from RPG Diffusors, we designed the studio piece by piece. He has developed his own software to mathematically calculate room dimensions in order to minimize bass buildup due to standing waves. A standing wave is a wave whose half-wavelength is corresponding to one of the three room dimensions. The ratio we arrived at was based upon a complex relationship between height, length and width that gave the least bass accentuation."

And also:

"D'Antonio's idea was to build a room with an acoustically absorptive wall at the speaker's side, and an active rear wall opposing the speakers. To prevent damaging reflections from the rear, we needed to spread the sound in random patterns. He made the world's first third-generation diffractal"

If you have additional sources that are more specific about the division of design dutuies, I'd love to see them. I'm always interested in reading about acoustics.
