Apertura Swing Bookshelf Speakers (Pair)

DRIVE UNITS

• A 16cm mid/woofer with an « isotactic matrix », cone like in Armonia, Edena and their big sisters. This material made of woven polypropylene strips, combines stiffness, lightness and good damping properties.
• The long moving coil allows a long linear excursion. Which is quite amazing for a speaker of this size.
• This drive unit comes also with an original suspension, featuring radial stiffeners that lower the interferences.
• High frequencies are reproduced by a tweeter, member of the famous “Ring Radiator” family.
• In addition to its unusual profile, it has a bullet shape waveguide and a rear damping chamber. The result is an extended frequency response, both at the top end (to above 40kHz), and at the bottom end to allow easier coupling with the bass/mid range drive unit.

CROSSOVER

• High frequencies are reproduced by a tweeter, member of the famous “Ring Radiator” family.
• In addition to its unusual profile, it has a bullet shape waveguide and a rear damping chamber. The result is an extended frequency response, both at the top end (to above 40kHz), and at the bottom end to allow easier coupling with the bass/mid range drive unit.
• Proprietary « DRIM » structure with a triple attenuation slopes
• This technology cancels intermodulation on each sections of the crossover, which result in unsurpassed clarity and resolution
• Same high level component qualities as in Sensa
• Each set of drive units (tweeter and mid/woofer) are individually measured and crossover values adjusted according to these measurements sets.
• Hand wiring on a 140 µm copper printed circuit board.
• Optimized crossover structure to avoid magnetic interference between components

ENCLOSURE

• The main goal, with this new cabinet design, was to limit vibration propagation on the most critical panels (especially on the back panel).
  High thickness panels (18mm)
• Internal dual cavities framework with one bracing panel to stiffen the structure and create very specific areas where damping materials can be applied
• Optimized bass reflex loading allowing reproduction of low frequencies, uncommon for such a size speaker.
• Importance is given to damping treatment to cancel any standing waves. We are using 2 different types of dumping materials
