– very sensitive with 2.5 grams of moving mass
– Xmax of 12 mm p-p
– very robust construction reminiscent of basic elements
– powerful neodymium magnet
– 2 x 8 ohms (two individual voice coils, VC)
– connection, soldering or cable lug (2.8 mm & 6.3 mm)
It comes with a punched-out rubber gasket of 1.8 mm for sealing & damping.
Delivered in a protective box.
The A3S is a breakthrough full range loudspeaker driver design comprised of a patented motor structure, patent-pending suspension and patent pending basket.
The A3S has an exceptionally flat response from 40Hz to 22Khz with very high power handling and dynamic range.
The A3S is built like a high power sub woofer driver using a large neodymium motor structure, big voice coil and suspension venting.
The A3S is ultra responsive at 2.5 grams total moving mass providing state of the art resolution and dynamic range.
The A3S sports 12mm of usable excursion with less than 1 dB compression at levels up to 95 dB SPL.

Fits many different constructions from individual elements and easy to build column models (line array speakers).
Column speakers provide a better dispersion of the sound, which is often an advantage.
Or why not for installation in a wall or ceiling.
The advantage of really full range driver, is that you don’t need a crossover filter, which avoids phase shifts and gives a cleaner and uncolored sound.
This works great with these particular elements, due to the fact that they are so wide-band.
It comes with a 1mm rubber gasket for sealing.
Dual Voice Coil, dual coils 2 x 8 ohms, allows to connect for 4, 8 or 16 ohms.. Easy to configure together with several elements.
