The Imagine Subwoofer

A Brief History

The Imagine I6SW was the rst subwoofer ever oered by Hybrid Audio Technologies. Originally designed to suit saddle-bag installations on touring motorcycles, the ecacy of the design was quickly proven in a wide variety of installations in virtually any automobile, where a small enclosure subwoofer could be used where space was at a premium.

In Spring 2009, the rst I6SW prototypes were developed by company founder and lead designer Scott Buwalda, and the concept of an Imagine subwoofer line-up was born.

All the while the I6SW had been developed and launched to an enthusiastic reception of enthusiasts, custom installers, and motorcycle and ATV riders, we were working on the larger counterparts to the Imagine I6SW, the 8-inch Imagine I8SW and the 10-inch I10SW. In January 2011, nal prototypes were approved for production after a long and strenuous program of evaluation by several Hybrid Audio specialty retail dealers for their use and assessment in the eld. The combined eorts of our dealers and our own R&D team armed the design concept for a budget-friendly high-end sound quality subwoofer, and the I8SW and I10SW product was commenced. Production began in August 2011, and was completed in October 2011, after an in-process change was made to the reverse-roll surround to ensure reliability and longevity operation. The Imagine I8SW and I10SW were launched in late November 2011.

In September 2013, the Imagine subwoofer line-up was deemed complete with the long-anticipated Imagine 12-inch oering, named the Imagine I12SW-V2, or version 2, as the Imagine subwoofer line-up now enters its Version 2 phase to include the Imagine I6SW-V2 (the Imagine I8SW and Imagine I10SW remain the most-current 8-inch and 10-inch subwoofer models in this line-up, respectively). The Imagine I12SW-V2 was the subject of a considerable level of prototyping and real-world testing to conclude on a design that incorporates exceptional output and power handling, but also low distortion, moving mass, and inductance. Likewise, the V2 version of the widely-acclaimed Imagine I6SW

incorporates several mechanical enhancements, making the driver more amenable to a wider variety of enclosure designs

Attributes

Basket/Frame

The basket of the I6SW-V2, I8SW, I10SW, and I12SW-V2 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 ush and iso-mounting for easy grille clearance and locational clearance (such as underneath a seat, in a touring motorcycle saddle bag, or in a center console enclosure).

Motor and Voice Coil

The motore of the Imagine subwoofer is conventional dynamic with a large, high-grade ferrite magnet assembly with bumped and vented pole piece. The voice coil diameter for the four subwoofers 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 signicantly reduced moving mass. The result is an extremely light weight winding, with low inductance and good power handling.

Suspension, Cone, Tinsel Leads & Terminals

The inverted surround is butyl rubber which is highly consistent, and does not suer the variance

of natural rubbers. This rubber surround terminates mechanical vibrations well, having a low stiness 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 stiness desired without being overly brittle or sti, where vibrations in the spider are well damped and do not translate into the former or the cone.

The Imagine subwoofers are cone-type drivers 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 Imagine subwoofers are used in all-weather climates, such as motorcycle, ATV, golf cart, and marine uses. 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 Imagine subwoofer comes equipped with heavy-duty PCB-mounted male blade-type terminals on the Imagine I8SW and I10SW, and nickel-plated push terminals on the I6SW-V2 and I12SW-V2, and give the end user exibility in tinned wire or crimp terminal terminations.

Summary

The Imagine subwoofers are the ideal multi-purpose sound quality subwoofer speaker driver. Mechanical and electrical parameters are amenable to a variety of vented and sealed enclosures. At home in virtually any arrangement, the Imagine subwoofer is Hybrid Audio’s Stage II subwoofer, boasting exceptional performance and a high-delity design philosophy.

† Typically, in-car response including

vehicular “cabin gain”, or the gain

expected with subwoofer(s) installed in

the vehicle, will result in an extended

subbass response. This is a result of

these frequencies being below the

lowest resonance in the vehicle (typically

around 50-70 Hz in most vehicles). In

more practical terms, install the Imagine

subwoofer(s) into your vehicle and

you will see a dramatic improvement

in subbass and midbass output, much

more so than just simply listening to the
