Description
HELIX K 10S (2022)
Shallow design – rich bass
The K 10S is the ultimate problem solver when it comes to realizing particularly flat and compact enclosure designs. Its extremely low installation depth opens up completely new possibilities for installation without making any acoustic compromises. Thanks to its large double voice coil and low resonance frequency, the K 10S doesn’t need to hide from woofers with greater installation depth when it comes to bass performance.
Smart down to the very last detail
The extremely stiff sandwich paper cone in connection with the heavy-duty dual voice-coil not only converts amplifier power easily and without compression effects into loads of sound pressure, but also scores sonically with subtle beats.
A special highlight: the magnet system has a threaded hole on the back and thus allows the woofer to be fixed to the back panel of the enclosure. In this way, housing vibrations can be effectively reduced even with thin walls, because with flat constructions every millimeter of construction depth counts.
Flexible connection
The double voice-coil design offers more flexibility when selecting an appropriate power amp. Whether 1 x 4 Ohms, 2 x 2 Ohms or 1 x 1 Ohm impedance – this low bass specialist makes any configuration easily possible.
"All inclusive" for the do-it-yourselfer
In addition to the high-quality connection terminal with gold-plated binding posts, a solid protective grille and gasket are also included.
For optimal bass performance in DIY installations you can find recommendations for sealed and vented enclosures with all parameters such as net volume, port tuning frequency or DSP settings in our technical data sheet.
