Alto Music - Why you need the Primacoustic Rx5 Up Fire Recoil Stabilizer Helps isolate your studio monitors from whatever they rest on Tightens up bass response Eliminates sypathetic resonance with supporting furniture Helps give a truer representation of the audio coming from your speakers 1.2" h x 7.5" w x 9.5" dPrimacoustic has been at the forefront of studio accessories for over 20 years now. Despite it's simplicity in design, the RX5 Up Fire Recoil Stabilizer is an invaluable part of any professional producer or engineer's rig. By putting together a thick steel plate, a urethane foam base, and a thin neoprene surface, Primacoustic has managed to help wring every last drop of high-fidelity tone out of your monitors. Because sympathetic resonance and vibrations are eliminated with the use of these platforms, users notice an overall enhanced sound quality. Bass frequencies were tighter, dynamics were more noticable, and overall, a punchier mix was achieved. Another benefit of the isolation of the speakers from their stands is that mixes tend to translate better system to system. When you don't have to mix with the extra noise that vibrations and overtones cause, your music ends up sounding tighter and more balanced. The Up Fire version is angled by 10 degrees to have your speakers aiming up from a lower surface. Great for smaller desktop speakers.
