I paired this with the Infinity Reference 1300a 300-Watt Amplifier and let me tell you this thing hits hard. Don't let the price fool you, now it's not going to win any bass competitions but if you are looking for a quality sub in a quality enclosure to add some boom to your system, don't look any further you have found what you are looking for!

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend giving your subwoofer(s) 75% - 90% of the recommended RMS rating.
If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.
Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.
Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.
Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.
Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile
Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

I have 2 of these in a custom slot port box. And let me just say WOW. These subs for the price pound. I like insanely loud music and on some songs i have to turn it down. They are much louder than my friends kicker comps. So if your looking a cheap but great performing sub. Buy these.

I purchased the Infinity 1220se to efficiently use the 300W coming from my new Rockford Fosgate PBR300X1. I had been using an old 12" Sony Xplod I had purchased in the mid 2000's. The Infinity is rated at 94 dB of sensitivity compared to the Sony's 87 dB so I hoped I there would be an audible increase in sound output. Knowing that the dB scale is logarithmic every 3 dB increase in sensitivity is the same as doubling the power of the amplifier so going from 87dB to 94 dB should make my amp sound like a 1200W amplifier. I took this with a grain of salt knowing that manufacturers measure specifications a little differently and use tricks to "puff up" their numbers.
I received my Infinity 1220se and couldn't believe the size of the shipping box and immediately thought, "This is ridiculously huge and is going right back to Amazon!" I struggled to remove the 50# behemoth from its sturdy shipping box and quickly squeezed it in the modestly sized trunk of my 2014 Volvo S60 to hook it up. What I heard next was ASTOUNDING!! The Sony struggled to fill my car with bass while the Infinity easily filled my ENTIRE GARAGE with deep, rich, soul stirring bass. The garage door rattled and my dog ran for cover. My friends and I still can't believe that all this bass is created from only 300W. A friend hooked it up to his subwoofer amplifier with the same improvement in sound output and quality. To top it off, despite being ported, it still has tight, accurate bass. Needless to say I'm keeping my new subwoofer!

I put this sub in a $2500 set up with Focal Krx2's and everything sounds great. The base is tight, and clean. It even hangs well with the hip hop tunes, and rattles the car pretty good. The girlfriend likes how it looks too. Highly recommend if you are looking for quality base at a good price.

I have had the sub in my suv for about a month now. It is running on a class d Kenwood 600 watt amp and is amazing. I listen to a wide range of music and it performs well in every type. Highly recommend for anyone wanting to get an easy "bag" for your buck.

Previously had 2 1262W's in a sealed box however they were stolen. Purchased 2 of 1220SE's...boxes are huge and filled up the entire trunk. Noticed that there is definitely a difference when the speakers are sealed. Bass is noticeably tighter. Plan on taking the speakers out of their ported enclosure and into a custom sealed box asap. Happy that Infinity still offered the 1262W's even in this format.

Very nice sounding, hard hitting that surprised me! Great looking enclosure that I was proud to give my son for Christmas. He sold his last system with 3 Infinity 12" subs and was sick without some bass. Quality addition for the factory SHaker system. Sounds like a car with 2 10" or even 2 12" subs. Definitely would buy again!

I've ran this sub for about a month now. First on a alpine 250 watt amp, I thought it sounded good but not WOW loud. I recently put it on a Pioneer GM-D9601 I bought from here. It's CEA-2006 rated for 800 watts rms @ 2 ohms. Put some CLEAN power to it and it will rattle your brains. You know it's working right when your eyes start to lose focus.

It does NOT have a built in amplifier. Give our sales team a call if you need help finding a match.
