Detailed Information

Do you need acoustic treatment? Stand in the middle of your room, clap your hands, and listen. Hear that? That’s flutter echo, reflections, standing waves, and other acoustic anomalies that will impact the quality of your recordings and color what you hear when you’re mixing. Luckily, it’s a common problem, and an easy one to solve, no matter how big or small your room is. The Primacoustic London 12 room kit is designed for rooms up to 150 square feet, and it tames the most common acoustic issues you’ll encounter.

Conquers a multitude of acoustic concerns

Most rooms in either commercial facilities or residential dwellings have parallel walls. These parallel walls are great for aesthetics and floor plans, but they introduce a world of problems in a recording or mixing rooms. The first culprit is primary reflections. In simplest terms, this is sound bouncing off of walls near the sound source. These reflected sounds recombine and phase cancellation occurs, causing comb filtering. Obviously, with phase cancellation, you’re not getting a true picture of the sound, so your mix won’t translate well on other systems. Primacoustic’s London 12 room kit uses a quartet of Control Columns to tame early reflections. Positioned near the sound source, the Control Columns helps to “define” the listening area, making it easier to discern what is really happening versus hearing the reflections, making both mixing and recording easier.

The cure for flutter echo

When you clap your hands in your room, much of what you hear is flutter echo – essentially sound bouncing off the walls, ceiling, and floor. In a room this lively, it will be nearly impossible to add the right amount of reverb to your mix. The eight Scatter Blocks in the London 12 room kit are usually installed behind the listening position to help disperse flutter echo by absorbing some of the sound energy while allowing some of the energy to reflect back. This allows for a more natural sound at the monitoring position. And at Sweetwater, we know how important it is to have a true picture of what’s going on at the mix position.

Tame room modes to even out your room’s sound

If your room has pockets of strong or weak bass response away from the mix position, you have room modes. That’s a fancy way of saying that a pair of low-frequency sound waves are colliding. When these wave collide and are in phase, the bass response is unusually strong; if they’re out of phase, they cancel each other out, resulting in weakened bass response. If the bass response isn’t even across the room, your mixes will suffer. Use the two Broadband panels mounted in the corners to tame room modes and improves the bass response of the room.

Not your average foam

Primacoustic London room kits are made up of Broadway acoustic panels. These panels aren’t really what is conventionally called foam, as they’re made from a high-density 6lb-per-cubic-foot fiberglass. This denser material provides almost five times greater absorption than typical foam. That equates to less foam on the wall and more absorption for a clean look and better sound.
