The Infinity Reference 1220de provides superior performance to competing loaded enclosures primarily due to our revolutionary Slipstream™ Port. The slipstream port provides lots of surface area outside the box so that the air stays stuck together—the engineers call it an "Adverse Pressure Gradient". That gradual change from high pressure to low pressure eliminates the distortion we hear as "whacking". Because the area of the port in the middle is much smaller than the mouth of the port, the port can be MUCH shorter than a cylindrical port with a surface area the same as Slipstream’s mouth. That means it can fit into regular boxes. Stickiness outside the box is maximized by increasing pressure and stickiness inside the port is minimized by reducing velocity. The benefit of our technology is more bass output with greatly reduced port noise and distortion.
yo herd i herd thes and i could not belive just 2 of thes woffers were pushen that good of bass it well worth the money im gana buy 3
these go real hard. i have them hooked up to a 1000D PPI amp and getting a lighter lit in my car is a difficult task.
I bought these...about a month ago and hooked them up to my factory deck..with a 500 watt alpine amp..and these suckas hit hard... I cant imagine how my car will sound when i get my infinity 6x9 and 6.5 fronts and a deck! great price.. I hit harder than my guy who had 2 cvr kickers
