Primacoustic RX12 er et unikt produkt for å eliminere forstyrrende resonans mellom studiomonitorer og stativet eller platen monitoren er satt på. I tillegg strammer den opp lydbildet og påvirkningen av høyttalerelementenes bevegelse, som i mange tilfeller skaper unøyaktigheter og fasefeil i frekvensområdet. Forenklet sagt kan man si at Recoilene frigjør høyttalerens lydpåvirkning i rommet den står i.

"The Recoil Stabilizers are great! A huge difference from regular foam pads. They sound more stationary and connected. I'm quite happy with them."

Daniel Lanois
Engineer/producer - U2, Bob Dylan, Peter Gabriel, Emmylou Harris, Ron Sexsmith, Robbie Robertson

“My nearfield speakers sound better on the Recoil Stabilizers than they did without them. The bottom is solid, the vocals are clear and my speakers don't fall down. It's a great product.”

“I was suspect at first, but after a few minutes with the recoil Stabilizers I realized how much difference they made. Especially on the low end. I'm keeping these. They work. ”

 

This Monitor Isolation Pad is Incredibly Effective!
The Primacoustic RX12 Recoil Stabilizer flat monitor pad eliminates resonant coupling from the the nearfield speaker to the stand, giving you the most accurate sound possible from your monitor. The RX12 also provides a stable base for your monitor, with a non-slip neoprene top surface and multi-layer, multi-material construction. With the added mass of a laser-cut steel plate sandwiched by isolation foam, plus a high-density urethane foam base, the anti-recoil design of the RX12 is both stable and amazingly effective.

Features:

  • Improves transient response
  • Widens the sound field for better imaging
  • Tightens up the bass response for greater accuracy
  • Flat
     

The Primacoustic Recoil Stabilizer is a unique speaker mounting device that at once eliminates disruptive resonant coupling from the loudspeaker to the stand, while providing a stable base that reduces the recoil caused by the forward energy of the loudspeaker motion.

Made from three basic components, the Recoil Stabilizer is essentially a platform for the loudspeaker that features a high-density urethane base that isolates the speaker from the shelf, monitor-bridge or stand. This effectively decouples the loudspeaker to eliminate vibration-borne resonance to the substructure.

A heavy laser-cut steel plate is added and sandwiched between the isolation layer and a no-slip neoprene top. The steel plate introduces significant mass to the structure and serves to stabilize the speaker.

By reducing the backward 'recoil' energy as the speaker coil pushes energy forward, initial waveform transients no longer suffer lag and the sharpness of the resulting pulse is more defined. The result is significantly greater detail at all frequencies, with tighter bottom end and improved depth of field.

How It Works
Before we get into how the 'Recoil' works, it is worth understanding some of the scientific principles involved and what problems we are actually solving.

Sound travels through air and other mediums in waves. These waves compress at various frequencies called the wavelength. Longer wavelengths tend to travel further while shorter ones travel in a more direct line. Longer wavelengths require more energy to generate and once in motion, are very difficult to contain. With sufficient energy, long wavelengths will cause walls and floors to vibrate. Thunder shaking your house is a very good example of lots of energy applied to a low frequency.

Simply put, bass travels through just about anything while high frequencies are fairly simple to control. And what has all of this got to do with nearfield monitors or reference loudspeakers? Speakers produce bass frequencies that will transfer vibrations through the speaker stand to the floor, the walls and what ever else is physically connected to the speaker. This is called acoustic coupling. When sound vibrations couple with the speaker stands they resonate and produce unwanted sound coloration. To sum up, coupling causes a frequency bump at the resonant frequency which in turn changes the speaker's performance.

To solve the problem, engineers often employ urethane foam pads or other insulating materials under their nearfield reference monitors as a means to eliminate the acoustic resonance that occurs when the speaker and the speaker stand, (shelf or monitor bridge) couple. Good news- this does in fact effectively decouple the two devices. Bad news- it introduces a new problem that is best described as recoil.

Think of a rifle firing a bullet. The hammer strikes the firing pin which in turn causes the shell to explode, propelling the bullet forward. As the bullet pushes forward the rifle recoils backwards to absorb the energy. This is exactly what is happening when you place your speakers on a soft, spongy material; during a transient such as a sharp kick drum thump, the forward momentum of the speaker is dulled by foam as the soft malleable substance allows the speaker to tilt backwards and recoil. This 'recoil' may be desirable when firing a rifle, but with a loudspeaker, the movement dulls the initial transient at the start of the wave, and the result is predictable: you lose clarity and detail.

What we really need is to decouple the source and provide a stable platform
The Recoil Stabilizer solves the problem by introducing a heavy mass on top of a high-density urethane isolation pad. By significantly increasing the mass of the base platform, the loudspeaker's forward momentum is no longer sufficient to move the platform backwards. It is stabilized and the recoil is significantly reduced.

If you think about it, this is exactly how a gyroscope works. Gyros are used in airplanes, torpedoes and missiles to stabilize the navigational system so that the device stays on course. By rotating a heavy mass very quickly (like the earth around itself - around the sun!) the centrifugal force retains the gyro's position relative to all axis. Since we need only control the effect from the speaker excursion on a single axis (front to back) we do not need a centrifugal force to steady the device, we can do the job with a simple, heavy steel platform that acts as the stabilizing mass.

This heavy platform is in turn, sandwiched between the isolation pad and a non-slip neoprene layer. This works double duty by providing the speaker with a comfortable place on which to sit while also working in sympathy with the bottom urethane foam and mass of the speaker to dampen the steel plate. To further reduce self-resonance, a curved front panel aids in the process by varying the impedance thus eliminating internal standing waves. This also adds more mass without increasing the footprint.

A wide range of Recoil Stabilizers are offered to accommodate various loudspeaker manufacturer offerings. This includes smaller Recoils for compact monitors like Auratones and larger Recoils for midfield monitors and sub-woofers. After many listening tests, we have found that a 4:1 ratio appears to work well whereby the mass of the Recoil should equal 25% or more of the loudspeaker being used.

A roundup of various loudspeaker brands and popular models is available to help individuals select the most suitable Recoil Stabilizer to suit their needs. Recoil Stabilizers are available in horizontal as well as angled models to aim the reference monitor to the engineer's listening position.

So there you have it. By first isolating the speaker from the stand or shelf, you eliminate harmful resonance and by stabilizing the speaker by increasing the mass of the base, we directly affect the loudspeaker's inertia and recoil is significantly reduced. The result - greater clarity and improved depth of field is immediately apparent. The Recoil Stabilizer is likely the most cost effective means to improve reference monitor accuracy for engineers at all levels.
