Aperture-II Acoustic Treatments By Stillpoints


The Stillpoints Aperture II gives you both absorption and diffusion at the first reflection points of a system. Like a mini black hole to absorb room interference. Mount them on the wall or next to your speakers on the Stillpoints custom stands.


Product Description


  • The Stillpoints Aperture II has been found to be effective from 40 Hz to 40kHz.
  • The Stillpoints Aperture II’s unique trapping system captures an area of waveform much broader than its small surface area would suggest.
  • The Stillpoints Aperture II can be used to trap waveforms either facing the wall or, facing away from the wall.
  • The Stillpoints Aperture II design allows for artwork or photographs of your choice to be inserted in the frame thus raising the aesthetic appeal for everyone in the home.
  • The Stillpoints Aperture II effectively increases soundstage width and depth. This is especially true
 for smaller rooms (see Michael Fremer’s review: Stereophile, Feb 2016.)
  • The Stillpoints Aperture II will increase the dimensional perspective of the image structure.


The Stillpoints Aperture will NOT:

  • Decrease or limit the dynamics of the system.
  • Diminish the power of the bass attack.
  • Unevenly control one frequency over another. (This is often the case with traditional room treatments)

Choose from three “STANDARD” natural wood frame species: Oak, Cherry, & Walnut.

Three products in one

The Stillpoints Aperture II acoustic panels represent a whole new form of acoustical treatment.
 It is actually three products in one: an absorber, a diffuser, and a resonator. 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 Stillpoints 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 explain the reality of how the Stillpoints Aperture II actually performs.

How it works

When using conventional acoustic panels made of typical absorbing materials, there will be only one volume level at 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 waveforms 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.


“They will treat standing waves, and they can tidy up troublesome corners; but after several months’ use I see them as an invaluable tool that focuses the music, and reduces boundary effects. The Apertures are also the perfect accompaniment to a Stillpoints-equipped system: together they work brilliantly.”

“The improvements brought on by the Stillpoint Apertures in my humble opinion are stunning and are hereby a must have. This review would be unjustified if I did not mention the cost factor. What the guys and gals at Stillpoints have done with regard to design, engineering and manufacturing of this product is an asset to the hi-end audio industry. Remarkably, what makes an even better story is their $650.00 price tag. Another great option is to have your panels designed with art of your choice (of course, this comes at an additional cost). In terms of build sound quality and taking into account today’s pricing in high-end audio, the Stillpoint Apertures are one hell of a bargain. I absolutely love them and I HIGHLY RECOMMEND them.”

Positive feedback
“You couldn’t tear the Stillpoints Aperture IIs away from me if you tried. And I would venture to say that anyone who gave them a try, even in a smaller space, would get results similar to what I’ve experienced here. If this is a rave, then so be it!

Amigos, you can put the Stillpoints Aperture IIs on your very short list of system-enhancements-that-I-must-have…guaranteed.”

“Stillpoints’ Aperture II panels made suspending disbelief in time travel and teleportation far easier, and that late-evening excursion affirmed why I got involved in this crazy hobby in the first place.”
