Acoustic Knowledge Base

Acoustics designer James Lindenschmidt joined Gravitas Create for a live Facebook Q&A, fielding questions from the community about studio acoustics setup. Gravitas Create compiled the full session into a report — this article links out to it. A useful resource for anyone with questions about treating a studio or listening room.

Building on Part One, James Lindenschmidt dives into subwoofer placement strategies for flattening bass response — from basic corner placement to ¼ null-point positioning, crossover tweaking, and using two or four subwoofers to cancel out axial modes. An essential read for anyone with a subwoofer/satellite system looking to maximise low-end accuracy.

Getting speaker placement right means balancing two competing problems: stereo imaging and accurate bass response. In this first of a two-part series, James Lindenschmidt explores equilateral triangle setups, dual monitor configurations, room modes, SBIR, and when subwoofers can solve the compromise entirely. Essential reading for anyone setting up a listening room or studio.

1D diffusors scatter in one plane, 2D in both — but which is right for your room? This guide breaks down the real differences between one-dimensional and two-dimensional diffusion and explains which works best for listening rooms, live rooms, and everything in between.

Diffusion is the most misunderstood acoustic treatment option. This deep dive breaks down the three main types — Reflection Phase Gratings, Geometric diffusors, and Binary Amplitude panels — explaining how each works and when to use each one.

Can you just mix on headphones? Technically yes — but the mixes won't be as good and your ears will pay the price. Here's why proper speakers in an acoustically treated space produce better results, faster, with less listener fatigue.

Bass traps absorb treble too — which means over-treatment is a real risk. This in-depth guide walks through every treatment option available for small rooms, from full-range broadband absorption to diffusion and hybrid panels, and when to use each.

Frequency response graphs only tell part of the story. The Energy-Time Curve (ETC) in Room EQ Wizard reveals how early reflections behave over time — and what to do about them. A deep dive for anyone serious about understanding their room.
