PostSubject: RoomTune Placement Guide   Fri Mar 20, 2015 7:31 pm


"One of the very first tweaks audiophiles do after getting their stereo system is make the acoustics in the room sound good enough to allow the music on the recordings to come through as real (life like) as possible. The room is the biggest audio component and dictates the overall sound of the system.

The RT Basic Setup

This is no different from what I do on the recording end of the audio chain. Playback is about restoring what was done not adding to or taking away from the original."

This RoomTune product thread shares not only what the RT Pillow Treatment is, but why it is.

RoomTune is chosen for many of the worlds reference rooms as their acoustical design and treatment, such as the rehearsal and recital rooms at the Eastman School of Music (seen above). It is important to us when designing any audio product that it is created for it's ability to restore sound. You can also see the three main treatments that make up the TunePak (a ten piece set of treatments). This is the starting point of converting any room into a concert hall.

Below the TunePak. The TunePak is made up of 3 fitted acoustical treatments that allow you to make tuning your room a simple process.

How room acoustics work.

When we listen to sound in our rooms we are listening to air pressure. Sound waves do not traveling in a straight line to our ears, but instead spherical patterns called sound pressure.

taking a look at how loading developes in a your room

There are 2 main parts to what the sound pressure (build up) is doing. One, pressure zones, the other, laminar flow.

Laminar flow (laminar effect) happens along every surface in the room. As sources like a speaker or instrument for example creates a sound the waves move out from that point in a spherical pattern till they hit a surface.

All surfaces do some diffusion and some absorption, as well as vibrate becoming a source themselves. The walls, floor and ceiling are the biggest sources and as the oncoming waves hit them, the wall will feed back into the room it's own set of waves that push against the oncoming. This activity creates a flow of sound that travels along the wall, floor and ceiling which intersect in the corners forming corner loads.

This constant build up of energy is in every room and is what you hear. As the pressure forms it makes pressure zones that you can easily listen to as you walk around the room talking or making sound. Some areas are at a plus signal and some at a minus.

Sound in your room looks like this.

Pressure Zone Controlling and RoomTuning is what we have named taking control of the zones and other effects in the room, helping it to perform naturally and in harmony with the music content.  

Another look at the room loading so you can see how and why we treat in the areas we do.

Here is the RT Pillow product line and placement guide.

Starting with the CornerTune.


When tuning a room it's best to get to the acoustical origins of the room first. Typically this build up happens in rooms upper corners. The lower corners are somewhat broken up by the furniture in the room, so the upper areas are the major points of loading. Walk to any of your corners look up and talk and you will hear what I mean.

With intent to restore the music, you don't want to kill the sound by having the burn side facing you. Let the energy get behind the RoomTune and burn while the live side of the pillow keeps the music linear.

As you treat your room your going to find the live side facing the listening position is almost always the best sounding. You can tell the burn side from the live by touch. The burn side feels soft while the live side you can feel the acoustical membrane.

Got the upper corners done, surprising isn't it?

Your on your way to being master of your listening room. The RT pillow products will do more for your sound than almost any tweak you can possibly do for your music. Instead of your speakers fighting the room they are starting to work with it.

Let's add the Echotune.


As you start tuning your upper mid-seams with the EchoTune some huge changes in the music begin to take place. The dynamics increase as well as the focus.

We put two EchoTunes in your TunePak, but you might want to treat all your upper mid-seams. Using one on the front wall and one on one of the side walls is great but many listeners choose to tune all their upper areas of build up. My recommendation is follow through with the rest of the TunePak placement instructions then begin to play around with some acoustical tricks which I'll show later.



Things are getting serious now and your room has become a completely different listening environment from where we started.

The RoomTune pillow treatment has a response of 16hz-22khz covering the entire music spectrum. We do make a 12" x 48" XXLT version for bigger rooms.
