Aperture II Acoustical Panel

The Stillpoints Aperture II acoustic panels represent a whole new form of acoustical treatment.
These are actually three products in one: an absorber, a diffuser, and a resonator. The effect of adding these panels to any audio system is profound, retrieving depth, presence and resolution previously obscured by noise.

Aperture acoustic panels represent a whole new form of acoustical treatment. Due to its revolutionary design, it is impossible to directly compare the performance parameters of the Stillpoints Aperture to a conventional acoustic panel made of fiberglass. The performance specifications of the Aperture continually adapt to the dynamic changes in amplitude and frequency of the audio/video system generating the waveforms within the acoustical environment. At any given amplitude and frequency a “snapshot” measurement of performance could be taken, but, that static measurement does not fully capture the reality of how a Aperture actually performs.

When using conventional acoustic panels made of typical absorbing materials, there will be only one volume levelat which the absorbing material will control the acoustic energy within the room adequately.(This is a static system.)At volumes above that level, you would need more absorption. At volumes below that level you will have too much absorption and the room will sound lifeless, dark, and dull. The Stillpoints Aperture utilizes a blend of absorption materials, and a unique design of internal chambers to trap acoustic energy. The diffusion aspect of the Stillpoints Aperture breaks up the wave forms which will aid mid to high frequency absorption and reduction. The resonator aspect of the Stillpoints Aperture offers control of the lower frequencies only when it’s needed. Thoughtful placement can achieve wonderfully controlled bass frequencies with dynamic lifelike quality and speed. With bass energy controlled, one can enjoy a light, lively, sparkling room of shimmering cymbals and explosive drum attacks, with wonderfully clear midrange and vocals at all amplitude levels.

The Stillpoints Aperture is the only acoustical product that will give you both absorption and diffusion at the first reflection points of a system. And you want both!

- The Stillpoints Aperture panels have been found to be effective from 40Hz to 40kHz!
- The Stillpoints Aperture’s unique trapping system captures an area of wave form much broader than its small surface area (just 22" SqIn) would suggest.
- The Stillpoints Aperture traps waveforms facing the wall or facing away from the wall
- The Stillpoints Aperture dramatically increase soundstage width and depth. This is especially true for smaller rooms. (See the Michael Fremer review: Stereophile, Feb 2016.)
- The Stillpoints Aperture increases the dimensional perspective of the image structure
- The Stillpoints Aperture Stands are lightweight and easily placed
- The Stillpoints Aperture Stand allows for easy Aperture auditioning on location without need for attachment to the wall surface.
- The Stillpoints Aperture Stands allows for close proximity positioning of the Stillpoints Aperture near a loudspeaker to control energy where a wall is not adjacent to the speaker.
(ie: When speakers are not located symmetrically to the room boundaries.) 
- The Stillpoints Aperture Stands allow for up to three Apertures to be hung on each side of the stand if desired.
- The Stillpoints Aperture Stands are very easy to move within a room for tuning vs conventional treatments that must be permanently fixed to a wall or ceiling surface.

The Stillpoints Apertures will not:
•  Decrease or limit the dynamics of the system.
•  Diminish the power of the bass attack. 
•  Unevenly control one frequency band over another. (As is often the case with traditional room treatments)
