Improve the sound of your room!

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.

Primacoustic London 12 Acoustic Treatment Room Kit at a Glance:
  • Reduces early reflections for a cleaner sounding room
  • The cure for flutter echo
  • Tame room modes to even out your room's sound
  • Not your average foam
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.

Look and Sound Great!

I could not be happier with the results of adding these acoustic treatment panels to my home office/studio.

Incredible transformation.

My studio is set up in a corner at one end of a long, narrow bedroom with windows in two corners and a wide glass door to a balcony in the middle of one wall. An acoustics nightmare. Clapping my hands in here made horrific ringing flutter echoes. I finally decided to go all in with the London 12 set.

The room is transformed. Just having a normal conversation in here is enough to tell the profound difference the panels make. Listening to and playing music in here is an absolute pleasure. I never realized how fatiguing sound was in here before. My monitors sound so much better! Since I put the panels up I've spent hours just listening to music.

The panels did have a pretty intense contact cement odor fresh from the box. I let them air out in the garage for a week before bringing then into the house, and absolutely no "new recording studio smell" remains. I also tried an experiment, using heavy duty picture hanging command adhesive strips to stick the metal impaling panels to the walls to prevent making a ton of holes. Worked well so far!

Wish I'd done this years ago.

Works great, looks great

Easy install. I decided to put one of my old mixes up as a test and the difference was mind blowing. I even heard parts of samples that I had never even noticed before. Great product. Easy purchase.
Rated 3/5

Great Panels, bad smell

Not sure if this has anything to do with the product or just the way Sweetwater delivered them, but when I opened up my boxes with the panels, they had a weird smell to them. Smelled like dried fish and a hair salon. After spraying with a ton of febreeze, the smell has dissipated, but not after leaving a pretty bad water stain on one of my panels.

Panels are pretty easy to install and hang with some good measurements, and they are of nice quality. Just could have done without the smell.
