The Imagine I6SW is the first subwoofer ever offered by Hybrid Audio Technologies. Originally designed to suit saddle-bag installations on touring motorcycles, the efficacy of the design was quickly proven in a wide variety of installations in virtually any automobile, where a small vented enclosure subwoofer could be used where space was at a premium. In Spring 2009, the first I6SW
prototypes were developed by company founder and lead designer Scott Buwalda, and the concept of an Imagine subwoofer line-up was born.
The Imagine I6SW is a 168mm (6.6-inch) subwoofer driver to compliment a wide variety of front stage system designs. The following are the I6SW’s design attributes:
Basket:
The basket of the I6SW is a stamped steel design with semi-gloss black powder coating. The frame includes spider venting for improved thermal power handling. The frame includes reverse-roll surround tooling proprietary to Hybrid Audio Technologies, allowing for close-tolerance flush and isomounting to easy grille clearance and locational clearance (such as underneath a seat, in a touring
motorcycle saddle bag, or in a center console enclosure). Product Parameters and
Specifications:
The motor of the I6SW is conventional dynamic with a large, 96-ounce (2.72 kg) high-grade ferrite magnet assembly with bumped and vented pole piece. The voice coil diameter of the I6SW is 51mm (2-inch) for elevated power handling, dissipation of heat (thereby lowering power compression), and maximizing the size of the magnet around the voice coil for enhanced motor compliance. The voice coil is a four-layer, high-purity aluminum, which is superior to copper for heat dissipation, as well as significantly reduced moving mass. The result is an extremely light weight winding with good power handling.
Suspension, Cone, Tinsel Leads, and Terminals:
The inverted surround is butyl rubber which is highly consistent, and does not suffer the variance of natural rubbers. This rubber surround terminates mechanical vibrations well, having a low stiffness for positive damping of resonances. The spider material was chosen for optimal performance; the spider is a 90/10 cotton/Nomex blend with single-dip low viscosity phenolic. This material provides
the stiffness desired without being overly brittle or stiff, where vibrations in the spider are well damped and do not translate into the former or the cone.
The I6SW is a cone-type driver consisting of a polypropylene diaphragm with low moving mass. Polypropylene provides a good balance of strength, moving mass, and water resistance, in the event the I6SW is used in touring motorcycle application. The tinsel leads are bonded directly to the former and brought out to the terminals, which keeps tinsel lead slap to a minimum and does not compromise the structural integrity of the cone. The I6SW comes equipped with heavy-duty PCB mounted male blade-type terminals that are nickel plated to optimize contact, and give the end user flexibility in tinned wire or crimp terminal terminations
