At Arrowzoom, we’re always inspired when creators take bold steps to elevate their audio environment. And sometimes, the timing aligns perfectly.
Recently, YouTuber and voice actor Grohlvana set out to build a dedicated voice acting booth inside a closet in his home office. As fate would have it, right as he started planning the project, we reached out with an offer to send him some of our acoustic treatment products.
What followed was a full booth transformation—unboxing, installation, testing, and honest review—all documented on his channel. Here’s a look at his experience from our perspective as the sponsor.
Why Grohlvana Wanted a Dedicated Booth
Grohlvana has been diving heavily into voice acting, recording thousands of lines and taking the craft more seriously than ever. With that growing dedication came a clear need:
✔ A consistent, controlled recording environment
✔ Reduced reflections and ambient noise
✔ Better clarity for professional-grade voiceover work
A closet is a popular and effective foundation for a DIY booth. But the space only reaches its full potential when paired with the right acoustic materials—exactly the role Arrowzoom products are made to fill.
Unboxing the Arrowzoom Acoustic Treatment Bundle
We sent Grohlvana two of our best-selling acoustic solutions to help him get started:
1. Arrowzoom Pyramid Series Acoustic Foam (Black & Blue)
These high-density absorption panels are perfect for minimizing reflections, especially in tight spaces. Grohlvana chose the black and blue bundle to match his channel’s aesthetic—and his personal love for the blue/black color combo.
2. Arrowzoom Diffuse PRO Square Felt Wooden Panel
These premium panels combine diffusion with visual style. The wooden-grain exterior instantly caught Grohlvana’s attention, offering both acoustic benefit and a clean, modern look inside the booth.
Each shipment also included installation tools: gloves, adhesive tape, wipes, and expansion instructions for the foam panels.
Installation: Mixing Style With Acoustic Performance
After allowing the foam tiles to expand for 24 hours, Grohlvana began installing the panels throughout the closet. Despite the tight quarters, the build went smoothly—and the end result was a unique, visually striking blend of:
-
Blue pyramid foam
-
Black pyramid foam
-
Wood-grain diffusion squares
For added stability, he supplemented some foam tiles with push pins—common in DIY setups.
Even with partial coverage, the booth immediately felt more controlled, signaling that the treatment was doing its job.
Before & After Sound Tests: The Arrowzoom Difference
Grohlvana conducted multiple sound tests to highlight the real-world improvements:
Untreated room
Natural echo, sound bouncing around the space.
Untreated closet
More contained, but still reflective.
Arrowzoom-treated closet
A notable shift toward:
-
More focused vocal tone
-
Reduced ambient reflections
-
A “pocketed,” punchy delivery
-
Cleaner line endings and beginnings
For a voice actor, this kind of control is invaluable—and it didn’t require expensive studio construction. Just smart treatment and careful placement.
