The "INSIDE SCOOP" on Amina Technologies and the world of high performance invisible speakers

Amina Speakers - Not Just for Walls and Ceilings

Amina flat panel speakers can also be built into furniture, such as conference tables or wall units, as it can transmit through solid, rigid materials such as hardwood, MDF, ply and man-made materials, milled down to up to 3/16 inch thick, except through materials with high resonance such as glass and metal. For those applications we use specifically […]

Phase Response and Time Alignment

An even larger benefit (tom the Amina technology) is in the phase response, in which the time/phase relationship between fundamentals and harmonics create the timbre, the voicing or signature of the instruments. From a planar surface there is only one point-in-time from which the sound originates, This means no multiple devices combining complex waveforms with […]

The World’s Largest Sweet Spots

The dispersion characteristics of the Amina in-wall speakers are half sphere, 180 degrees. Even at 85 degrees off-axis, the listener still gets the same type of frequency response as those that are sitting on-axis to the speaker (the panel produces a figure-8 di-polar response front to back in free air, resulting in a 1/2 sphere […]

A Word or Two Concerning Speaker Frequency Response

Frequency response for Amina flat panel loudspeakers has been intentionally limited below 120Hz and goes to 22 kHz for most models. HP filters keep LF vibration out of the device, and hence the wall. Though by definition considered a full range device, the LF or sub effects for music and video audio reproduction should be […]
