Years ahead of the crowd
The AVI SL Series automotive subwoofers, all Canadian made, feature improved HX glass-fibre cones for the optimum balance of weight and rigidity. All of the computer machined steel parts are chemically blackened to absorb heat from the voice coil and reduce dynamic compression. The voice coil itself is edgewound, using oxygen-free copper ribbon on a composite polyamide former, and tolerates peaks of 280 degrees Celsius, ensuring high sensitivity and power handling. The innovative magnetic gap design significantly reduces distortion compared to conventional types. The cast alloy chassis, necessary to support the massive magnet system, incorporates a heat-exchanger which further increases power handling and improves transient response.

High output levels demand subwoofers capable of moving large volumes of air, and this is where AVI really excels. Our subwoofers feature long excursion, high linearity suspensions for the maximum low-bass output ability of any speaker in their class. This advanced suspension design allows AVI subwoofers to survive peaks of three times their rated excursion.

The AVI SL Series are hand built in our own facility in Canada, using the finest components in the world, and designed with high fidelity as the primary criterion. It is a fortunate coincidence that designing subwoofers for musical accuracy also makes them capable of stunning output levels.

SL Series subwoofers are optimized for small vented enclosures, and may also be successfully applied in 6th order bandpass enclosures or with aperiodic membranes. Alternative enclosures are also possible, and AVI dealers can provide information on enclosure design and construction.

Evolution
Since AVI's beginning, the first 6-7 years the only subwoofer series were the SL Series. This line is not only the one that single handedly brought AVI it's reputation. Most important is the ability of this model to produce high power handling and sound quality. Never before has there been a subwoofer design that places emphasis on efficiency and precise response. Up until now, the SL Series remain in the elite subwoofer class all over the world. It has gone through 3-4 generations of slight improvements to bring them to near-perfect car audio subwoofers.

Through the success of the SL Series, the EL Series spawned from consumer demand of a less expensive line. In the recent years, the market demand and trend has been towards small sealed enclosures. This led us to develop the new entry-level SS (Small Seal) Series subwoofers. However, AVI's target group of consumer have always been extremely high-end individuals. That is why the SLS Series was created to maintain audio excellence while allowing the line to be used in small sealed or ported enclosures. This series brings car audio to a different level, and will be widely available in 2002. AVI's mission statement has always been to design speakers for sound quality as first priority, and not for SPL. However, when it comes to power handling, all of our subwoofers are more than able to handle high power outputs. For example, our GX-300 (12") subwoofer can handle over 1000 W RMS!
