Custom diffusers, scatter plates, and studio treatments designed and built by hand. No guesswork. No off-the-shelf shortcuts. Made in the USA.

Your Room Wasn’t Built for Music

But We Can Fix That

What We Do

We design and build acoustic treatments that work For Professionals.

QRD diffusers
Lattice diffuser arrays
Scatter plates for bass traps and clouds
Custom products for studios and listening rooms

Everything is built to spec. No decorative panels pretending to be acoustic treatment.

Let’s be honest:

Unless you’ve dropped seven figures on a special contractor, an
acoustician and a ground-up commercial build with floating floors and non-parallel
walls, you’re working in a space that was never meant to hear a kick drum or a high-
end vocal. Most of us are battling "bedroom bloom," garage flutter, or the harsh
reflections of a basement that was designed for storage, not sonics.
At Queen City Acoustics, we understand that your studio is likely a modified space,
and we know exactly how to fix the acoustic "hand" you’ve been dealt.
Precision Craftsmanship for Pro Sonics
We don’t believe in one-size-fits-all foam wedges. We are looking for Acoustic Engineers and Recording Studio Contractors who share our obsession with the physics of sound. We need
a partner capable of executing complex builds that turn architectural flaws into
acoustic assets, including:
• Mathematical Scatter Plates: Precision-milled patterns to maintain energy
while killing echoes.
• Massive Bass Traps: Robust, furniture-grade builds designed to tame those
unruly low-end standing waves.
• Diffusion & Absorption Arrays: From quadratic residue diffusers to
specialized polycylindrical panels.
Join the Queen City Build
If you have a deep respect for wood grain and a deeper understanding of how a well-
built panel can transform a room, we want to talk. We’re bridging the gap between
"home studio" and "pro facility" by providing high-end, custom-built treatments for
the spaces the rest of us actually live and work in. Help us build the gear that finally
lets the Queen City hear itself clearly.

Real Work. Not Theory.

Most acoustic products are sold as generic solutions. That’s not how we work. Every space is different. Room size, layout, materials-it all matters. We build based on the actual room, not a template.

Big Ideas,
Real Impact.

Driven by curiosity and built on purpose, this is where bold thinking meets thoughtful execution. Let’s create something meaningful together.

Our Studio Build Case Study

Full-room diffuser and treatment install using modular lattice arrays, quadratic residue diffusers, scatter plates and base traps. Designed to control acoustic reflections, improve imaging, and keep the room balanced while keeping the space fully functional.

Our Products

Space-coupling diffuser designed to introduce broad, multi-directional scattering.
The QCA Lattice Diffuser combines reflective surfaces and open areas to scatter mid and high frequency energy while maintaining a more open acoustic character. Often used in conjunction with absorptive treatments to create balanced hybrid environments.
- Space-coupling / lattice diffuser design
- Broad, multi-directional scattering
- Maintains a more open room response
- Effective in hybrid treatment systems and rear wall applications
- 24”x24” panels
Reflective acoustic diffuser based on a 7-well quadratic residue sequence.
The QCA-7 is designed to scatter mid and high frequency energy, reducing specular reflections and improving spatial response in smaller control rooms and listening environments. Its compact format makes it suitable for rear walls and areas where depth and space are limited.
- 7-well quadratic diffuser design
- Scatters mid and high frequencies
- Reduces flutter echo and specular reflections
- Compact format for smaller rooms and targeted treatment
- 24” wide and come in 24”, 48” and 60” heights.
Higher-order quadratic diffuser designed for more uniform acoustic scattering.
The QCA-13 provides smoother and more even diffusion compared to lower-order designs, helping to reduce directional reflections and improve imaging accuracy. Well suited for control rooms and critical listening spaces where more refined diffusion is required.
- 13-well quadratic diffuser design
- More uniform scattering than lower-order diffusers
- Improves spatial accuracy and reduces coloration
- Suitable for larger rear walls and critical listening environments
- 24” wide and come in 24”, 48” and 60” heights.
The QCA Scatter Plate introduces controlled high-frequency reflection while allowing low-frequency energy to pass through to the underlying absorption. This creates a balanced hybrid treatment, reducing over-absorption in the mid and high range while maintaining effective low-frequency control. Commonly used in control rooms and listening environments where a combination of absorption and reflection is required to preserve clarity and spatial response.
- Designed for mounting over bass traps or acoustic panels
- Reflects mid and high frequencies
- Maintains low-frequency absorption
- Simple integration into existing treatments
- Custom sizes
