Speaker Placement 201, Part Two: Using Subwoofers
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.
Speaker Placement 201: Part One
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.
The Diffusion Dimension Download: 1D vs 2D Diffusion
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.
Decoding Diffusion: Types of Acoustic Diffusors Explained
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.
Mixing & Listening: Headphones vs. an Acoustically Treated Space
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.
Unpacking ETC: Time Domain Measurements & Early Reflections
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.
The Basics of Room Acoustics and How to Set Up A Room
GIK Acoustics-Europe presented a discussion on room treatment basics and room setup at the HIGH END Show Munich 2016. A brief overview of GIK's approach and a link to the full lecture recap.
From patented designs and Class A fire-rated materials to free expert advice and proven acoustic performance, here's what separates GIK Acoustics from every other treatment manufacturer on the market.
The Basics of Bass Traps and Diffusion Panels
If you're setting up a home studio, listening room, or home theater in a typical residential space, bass frequencies are almost certainly your biggest acoustic challenge. In this video, GIK Acoustics walks through why small rooms struggle with low-end buildup, how bass traps and diffusion panels address the problem in different ways, and how to lay out a practical first treatment using TriTrap™ Corner Bass Traps, FlexRange® Bass Trap Panels, and GridFusor diffusion panels.
