Infinity Reference 1220de Dual 12 Inch Preloaded Enclosure with Slipstream Port Silver Black

Infinity Reference 1220de Dual 12 Inch Preloaded Enclosure with Slipstream Port Silver Black

The Infinity Reference 1220de provides superior performance to competing loaded enclosures primarily due to our revolutionary SlipstreamTM Port. The slipstream port provides lots of surface area outside the box so that the air stays stuck togetherthe 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 Slipstreams mouth. That means it can fit into regular boxes.

5 Stars Really the best bang for the buck!!
I purchased In March 2009 & have loved it since! I have a 99 Lincoln Continental & so trunk space was not an issue & I have had many other systems in other cars! Since my 1st infinity purchase in 2000 I have used only Infinity Kappa!! But these are great & have just as much bass as my older 2 12″ kappa’s & Love the box these come in! When & if I blow these subs I will use this box for some Infinity Kappa Perfect 12″s!

I was skeptical about a loaded enclosure untill now! I have 450×2 Rms amp on these with another 4 channel running all 6 speakers in car & have a 1/0 guage wire kit with a dist.box that breaks into 2-4 gauge wires! Clarity of Infnity is known with amps!

I listen to rock,rap,punk,classical & these subs perform like champs & have the solid hit of bass from rock or rap drums & I even tried a bass comp CD & holly crap! My firnds have spent $1000′s more for over priced hyped up junk! But unless your going comp. These are great!The shake the hell out of my big car & I can’t get rid of the rattles I have outside of car becuase its the trunk lid,tail lights & underside of the car that rattles & I cant keep a full can of soda in the cup holder with out it spinning around & going flat quick!! Trust me you can feel your ears & nose vibrate with most songs!! Just now wishing I had a hatchback now!!

4 Stars Great little setup
Fantastic looking setup from infinity. Big but not too big, it fits perfect in the back of my Mazda 6. This thing hits like a ton of bricks, even vibrates my nose. It does tend to be a bit boomy, though I am personally used to sealed enclosures. That is the only reason I did not give it a 5. The splipstream port offers absolutely silent air movement even at max volumes, which I have always been picky about, so that is great. Easy to wire up to a mono-block amp at 2ohms. I runit with Infinity’s 600watt RMS mono amp and it’s a perfect fit. Not much more to say about it, it is a great little setup.
