Acoustic Diffuser QD-13

No listening room, home theater, or recording studio is complete without proper diffusion. It’s an absolute necessity! The QD-13 acoustic diffuser from Acoustic Fields is the ultimate quadratic diffusion solution for energy in the 280 Hz to 3,400 Hz range. Although we didn’t invent quadratic diffusion, we think that after 25 years in the business, no one is doing quadratic diffusion better than we are!

Like with all our acoustic treatments, the QD-13 is furniture-grade, made from only the highest quality wood available. Our quadratic diffusers are extra special because we actually let you choose the material. Your listening room or recording studio will sound and look great thanks to the QD-13!

Enhance Your Listening Experience Like Never Before

This sound diffuser is independently tested and has been proven to produce consistent results. You never have to second-guess the kind of sound you’ll end up hearing when it’s been produced in a room with this diffuser.

Nothing enhances your listening experience the way a quadratic diffuser does! You get the full range of sound—every little detail that the artist and sound engineer wanted you to hear when they made the music. You’ll feel so much closer to the artist and their music than you would with inferior acoustic diffusers.

When you incorporate this acoustic diffuser into your room you will achieve sonic perfection! These diffusers allow all the middle and high frequencies to be heard equally. You’ll be able to hear every instrument individually. Music has never sounded this good! A room with only flat surfaces definitely can’t produce such high-quality sound.

If you position the QD-13 vertically, it will diffuse sound in a horizontal pattern. But if you position it horizontally, it will spread sound energy out in a vertical array of energy. When you have a diffuser that accomplishes both dimensions of diffusion, you produce sound that’s significantly better than any room using inferior diffusion.

Maximized Sound Produced in Medium-Sized Environments

A lot of people have the misconception that great music is made in a spacious environment. These quadratic diffusers shatter that myth! The QD-13 was created with small to medium-sized environments in mind. They transform the sound produced in smaller spaces, making it sound as if the room were larger.

Each of these diffusers is 12.5 inches deep, 48 inches tall, and 27.75 inches wide. You may have limited space, but you don’t have to sacrifice on diffusion! Music will take on a whole new form once you experience this diffuser. Quadratic diffusion increases the width of your sound stage. It will make your music sound as if it is coming from farther left and farther right than the true positions of your speakers.

Poor diffusion can happen in rooms of all sizes. It’s not the size of the room that matters most. The type of technology you’re using matters more than anything. And the best type of diffusion technology that’s available is quadratic diffusion!
