I want to share this article from stereophile.com by Art Dudley for today’s daily audiophile roundup. At a recent major audio show, Robyatt Audio representative Robin Wyatt showed off two Quad ESL loudspeakers, which have not been seen in years. They were refurbished by Quad expert Wayne Picquet with $10,000 Miyajima OTL 2010 amplifiers, with a custom preamp by Charles King. The sound was perhaps the best of the night, except the room size made it seem like the bass of the Quads was too much.
I love a proper restoration project so this story took my fancy. I hope you enjoy too:
Sweet merciful Quad

I’m seeking info for sanctuary reverberation absorbsion material ( panels) and best placement.
There may be apps that do that. You can definitely find spectrum analyzers that will measure ultra low.
Is there an APP that can measure the ultra low frequency levels?
