I'm building a new listening room (new home) which has a limited size (interior-16'w X 19.5'l X 10'h).
In my prior listening room which I had 39,000 LPs/78s on solid MDF shelving cabinets and on the floor and CDs in steel cabinets, with up to 11.5' high vaulted ceilings, multi-pane casement windows at first reflection and front wall, dual layers of drywall, etc. Not a great sounding room with plenty of slap echo. I treated the room with 2 pairs of Shakti Hallographs and 32 Synergistic Research HFTs. The slap echo was ameliorated during music playing and sound frequency spikes were diminshed (greatly). No problem with bass though. This current room sounds better than 95% of the 100s of rooms I've heard at audio shows and audio salons.
In the new listening only room (storage in an adjacent room), I'm building out the exterior walls with carbon filter absorption panels which are extensively built products unlike GIK cheap materials. What looks like an interior room solution room is quadradic diffusion along the front and rear walls. I doubt that the Stillpoints Aperture (I use only Stillpoints isolation products) would accomplish the same as these big, well built all wood products
https://www.acousticfields.com/product/sounddiffuser-acousticdiffuser-qd13/ Yes, they are expensive, but once installed, don't have to be moved or augmented. If I get to build my larger listening room, I would move them there. The goal of the QD is to smooth the frequency distribution resulting in a room sounding twice as large as it actually is. That's what I've been told. Also, no more drywall on interior facing walls, only natural finished wood (plywood). I anticipate that I will be able to duplicate my 40% current larger room with my smaller new room and add smoother mids and highs.
The room acoustics is half the sound. So many forums are concerned with small differences in sound for high priced equipment and tweaks. I'm starting with the acoustics first. I already have the equipment.
