Infinity Primus 12" 400-watt powered subwoofer Black
From the Manufacturer
Not just loud. Accurate.
Prepare to raise your expectations. Experience home entertainment at a new level of clarity and realism. From unobtrusive bookshelf systems to dazzlingly powerful home theaters, there's an Infinity Primus system that's right for every purpose and room in your home.
Let's be honest - there's not a whole lot to a subwoofer. It's one big speaker that likes to get loud and shake pictures off the wall. So what separates a good sub from the not-so-good? It's more than power: Give anything enough juice and it will get loud. The secret to a good powered subwoofer is its accuracy and clarity. We should know. We invented the powered subwoofer in 1968. We've come a long way since then. With the Infinity Primus PS312BK's Metal Matrix Diaphragm technology and low resonance enclosures, it possesses excellent transient frequency response - agile and sharp - and music is clean and movies rumble. Hear music the way it was meant to be heard, and experience a film score like never before, without the speaker changing or altering the sound - precisely as it should be. With its superb linear frequency response you can fill any room with sound you can feel. Got an older system? Bring it to life with an Infinity Primus PS312BK subwoofer. Give your system a soul - just make sure you've secured your pictures to the wall first.
Music and Movies as they were meant to be heard.
Patented MMD transducer technology improves sonic accuracy
Derived from our patented CMMD technology, the Metal Matrix Diaphragm (MMD) approach continues the Infinity tradition of using advanced materials to improve sonic accuracy. These diaphragms are much stiffer than standard metal ones - by anodizing both sides of an aluminum core, we're able to significantly improve cone performance and outperform cones made of paper, polypropylene or Kevlar material.

Powerful amplification delivers high output and low frequency extension
What we hear and feel as bass during your favorite action movie is actually the movement of air. The PS312BK really gets the air moving with an incredibly powerful 400-watt amplifier for high output and deep low frequency extension. While moving lots of air is great for those explosions and car chase scenes in movies, you also want an amplifier that is both accurate and efficient to deliver those more subtle bass notes that might come from your favorite musical track. Good thing that the PS312BK's amplifier is both powerful and audiophile enough to excel at both.
Low-Resonance enclosures do not change or alter the sound
A great sounding loudspeaker should play just what it's told to without changing or altering the sound. One way that a poorly designed loudspeaker can change the sound is when the enclosure resonates or vibrates. Resonance can change a speaker's overall tonal balance and totally alter the sound of the recording that it plays. To eliminate any enclosure resonance from the PS312BK powered subwoofer, Infinity engineers the enclosure using pinpoint internal bracing that increases rigidity so it does not vibrate or resonate. Bass sounds tight and deep with out being muddy or boomy. Plus there's the added advantage of a sleek, narrow enclosure that's at home in nearly any room decor.
Superior Infinity engineering delivers sound perfection
The Infinity Primus PS312BK's speaker drivers, baffles, cabinets and waveguides are designed to work seamlessly together as an integrated system - fitting together like pieces of a jigsaw puzzle. It begins with our ultra-precise transducers - the beating heart of the Primus PS312BK. MMD technology doesn't change, color or distort audio signal sound the way diaphragms made of other materials do. This combines with the Primus speaker's low resonance enclosures to compound the precision qualities of the transducer, further eliminating mechanical distortion.
Infinity - Legendary reputation. Uncompromising craftsmanship and sound.
With the Infinity Primus PS312BK, you not only experience the cutting edge in high-performance transducer technology and sound reproduction, you experience the cutting edge from the makers of Infinity products - some of the world's most innovative, high-quality audio equipment. The road to the Infinity Primus Series is a road lined with dozens of audio milestones: The Infinity Servo Statik 1a - the world's first powered subwoofer. The EMIT (Electromagnetic Induction Tweeter) device. The revolutionary IRS speaker - the world's first "reference" loudspeaker. The Prelude MTS speaker - the world's first powered tower speaker. Since 1968, innovative Infinity technologies, materials and manufacturing techniques have advanced the science of sound, and have set new standards in loudspeaker technology and performance. Infinity Primus Series speakers benefit from every Infinity innovation that has come before. This is where Infinity sound begins, and it's well within your reach.

Can be dialed up to 11 or all the way down to nearly off depending on how much boom you want or need. Game of Thrones causes closets, recessed lighting and plates to vibrate and rattle at 50% gain, hiphop/edm at full will cause things to fall off of walls.
Damn near capable of shaking your house off of it's foundation... and if you live in an apartment complex think about this purchase, do you really want to be that guy?
Oh if you need a great sub, this one is the one to get.
That being said, the below might be helpful for others:
Turns out the subwoofer setting in my Yamaha receiver was turned down really low and once I manually adjusted that and set the gain and crossover to higher levels, the bass rumbling started.
My Yamaha receiver came with a microphone to use as part of an auto setup feature and for some reason the mic set my subwoofer gain to be really low. Also, don't use regular RCA cables....unless you really have to. I noticed when I had regular RCA cables plugged in that the subwoofer was emitting a strange background hum noise. I bought a Belkin subwoofer cable through amazon and after plugging that in, the background noise hum went away.
I mentioned all of the above stuff in case others have had issues too.
So far, I have no complaints! If, as other reviewers have said, the subwoofer has issues a year from now etc..I will come back and update this review to reflect the change. But right now, I have to be very careful with how loud my overall volume is because the bass is superb on this and it really goes a long way to help with the movie immersion and I really like it.
