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 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 that are nickel plated to optimize contact, and give the end user flexibility 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-fidelity 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 50-125 Hz in most
