Features

  • Low-profile design: Because todays compact cars offer less space, the Infinity Reference Subwoofers are designed to fit into small enclosures. Theyre slim, sleek, stylish, and dont sacrifice on sound.
  • Harman-proprietary SSI (Selectable Smart Impedance): Unlike most dual-voice coil woofers, which provide either 1 or 4 ohms or 2 or 8 ohms, the Infinity Reference Subwoofers give the listener 2-ohm and 4-ohm, providing the two most often used impedances.
  • Frequency response 27Hz -175Hz: Your audio is filled with delicious sounds. Unfortunately, youre not always hearing them all. With lows that dig down into the depths of 27Hz, youll hear the low-end frequencies youve been missing.
  • OEM-level reliability testing: Infinity tests every speaker to the same rigid specifications as automakers, subjecting them to extreme conditions that break lesser speakers. We freeze them, blast them with ultraviolet light and drive them at full power.
  • Peak power handling: 1000W, Nominal impedance: 2 ohm or 4 ohm, switch selectable, 92dB Sensitivity

Description

The 1200S is Infinity’s latest Reference subwoofer offer incredible installation flexibility. Their low-profile design allows them to fit perfectly into even the most shallow of enclosures great for today’s compact cars. Polypropylene woofer cones deliver exceptional bass response at frequencies as low as 27Hz. But what makes these subs really stand out is their Harmanproprietary SSI (Selectable Smart Impedance), which allows the subwoofer to present the amplifier with either a 2 or 4 ohm load at the flip of a switch.

  • Shockingly good sound
Used this in a custom made box I built to fit under the seat in my 2019 Ram 1500. I am powering it with an AudioControl 1.800 in 4 ohm which gives about 500w RMS, although I have the gains barely turned up past half way. I have been pleasantly surprised at the quality of the sound. It is clean and clear, and hits harder than I expected it to. The box is built to the internal volume specs that Infinity provides, but as you can see, is a complicated shape to fit the various contours under the seat. The main part of the box is also lined with sound deadening (Stinger Roadkill). Would highly recommend if you listen to rock, alternative, acoustic, but likely won't put the door rattling bass out that those who listen to rap or techno are looking for. ... show more

  • Doesn’t disappoint
OMG this Shallow Subwoofer is a beast, paired with an Infinity Reference 600.1 and installed in a vented shallow mount enclosure, very loud and the bass is deep, you may not win any bass competitions but it will hold its own, I have it installed in the rear of a 2003 Mitsubishi Montero Limited facing the front, it is also surprisingly top quality at the value it’s being sold, if I didn’t need the 3rd row seat I would definitely purchase agian ... show more

  • Super sound quality for the money
I installed this sub in my 94 Chevy Silverado extended cab. The sub is installed in a down-firing sealed enclosure that fits the exact cubic inch size recommendation by Harmon. I seriously am amazed at the response and clarity of this sub. I am using it with 4 Polk Audio DB series 4 x 6 inch speakers and a JL Audio RD900/5. 2 key things to note. 80 to 100 hertz is perfect for a low pass frequency range on this sub. Harmon recommends 80...it will hit much lower ranges just set your slope to a mild setting and you will be surprised. 2nd thing is power. I am running this at 2ohms...pushing about 500 good watts to it. It's super sounding and PLENTY of bass for anyone looking to produce solid sound quality. If you are a bass head you might look elsewhere, that being said it does surprise me with its range and low response. JAM ON PEOPLE!!! ... show more

  • Good clean sub, but nothing special
I have these set to 4 ohms and been hammering it with an alpine 500 w amp for the last three months. So it's at least that durable. This sub can take RMS really well actually, listening to EDM musics or something is elongated beats this sub sounds pretty good. However, since it's a slim it just can't hit very hard. It's also pretty crisp, not muddy at all, so that's another pro. Overall, after owning this sub, I certainly don't regret buying it, because it's a good clean sub. BUT, next time I'd definitely go with something that can hit harder. If you want to add just a little bass to your system this is perfect, maybe even a little much. But if you're a bass junky, look elsewhere. ... show more

  • Funcionan bien!
Se escuchan bastante bien, los puse en un cajón sellado de 0.7 pies cúbicos y la verdad no se escucha tan profundo el bajo pero si maneja bien las frecuencias has 120 hz y se siente un golpe fuerte, creo que cumple con lo que promete, apenas tengo una semana con ellos, si pasa algo mas adelante actualizaré mi comentario... ... show more

  • Missing mounting hardware
Haven't hooked them up yet, but that's because they didnt come with mounting screws or any wiring. The wiring I sorta understand but not coming with mounting screws its pretty crappy. Anyways I'll update on sound when I get the rest of the hardware

  • Awesome sub for the price
This subwoofer is great for the price and performs very well for how shallow it is. I've had one in my 07 Corolla sedan for almost 5 years and it has never missed a beat. I purchased a 2nd one to use in my 22 Corolla hatchback and I'm happy with the sound performance. Definitely recommend

  • Subwoofer didn’t even last a couple of hours
Purchased this sub along with the “ Infinity Reference-6001A Reference Series Mono, 600w X 1 Amplifier”. The sub didn’t last but a couple of hours on the low end settings. The subwoofer started smoking, not sure what caused this as I’m not a bass head… just wanted a little bit more base on top of my factory Bose system and have always been a huge Harmen fan. I have asthma so this wasn’t very pleasant. Look elsewhere. ... show more
