Very clean and heavy bass.
Crutchfield customer from Sioux City, IA on 10/22/2020
I had infinity subs before and have been very pleased with the sound quality. This 12" sub fit nicely in the truck. And has taken everything I have dished at it. It just pounds the bass.
Pros: Pounds bass. Looks good.
Cons: None so far.

Good value

This little sub goes boom boom. I put it in a Cobalt and it definitely shakes the whole car. Pretty good for the price.

Good price, good bass
Crutchfield customer from Portland, OR on 7/1/2020
Thumps. Run with an infinity ref700 amp. Vibrates my insides.
Pros: 12 inch sub paired to its box generally means better bass. Infinity makes a decent product. I.e., this is a good setup.
Cons: None so far. No idea about longevity.

Great for the money!

For the money, this thing is great. Running it off my Infinity Reference 4555a amp. 320W @ 4 ohms. Overall solid construction, nice tight sound, looks great, etc. My two small complaints: The wire terminals on the back are kinda on the cheap side, not easy to break or anything but they just don't feel super solid. And the sub also doesn't hit very hard below 40z, which is fine. To be expected with a single 12" sealed box. I was just optimistically hoping for a little more. Most music I listen to it doesn't matter. If you want tour trap 808's to shake your car, this probably isn't the sub for you.
Pros: Price, construction, tight sound
Cons: Lack of response below 40Hz, cheap wire terminals

Infinity Primus 1270B
Crutchfield customer from Salisbury, NC on 6/1/2020

Very clean sound, as expected from Infinity. I have been a fan of Infinity speakers since I bought my first pair of RS3bs back in 1985. Although they were bought by Harmon a while back, they still didn't let me down! I bought this to replace a 10 inch sub that I originally had. Was pleasantly surprised that this sub didn't overpower my small car. While it CAN produce the annoying bass response that you hear from some vehicles, it can also be balanced well to compliment your system very well.

From Classical to Heavy Metal
Dave from Independence, KS on 12/5/2019
I put the Infinitely Primus 1270B and the Infinity Primus 6002A Amp which I Purchased from Black Friday sale in my Dodge Charger with Factory Alpine system and tune it by ear with the help the very friendly help of Tech Support Advisor Mike the 6002A amp is 140 Watts rms and peak power of 280 watts the 1270B Subwoofer handles 300 watts rms and 1200 watts peak this maybe slightly underpowered but is perfect for my car it made the very good sounding Factory Alpine system come ALIVE. Infinity is a Fantastic Product made even better by my Friends at Crutchfield a Big Thanks to sales Advisor Ace and Mike and the Amazing at People Crutchfield that Love their jobs.
Pros: Very affordable and Great Product Can't say enough

Great bang per buck
Ron from Copperas Cove, TX on 12/16/2018
Not really a fan of sealed boxes but I thought I would try it. Added this to a 2018 Altima stock system with the help of audio control's LC2i and MTX's Thunder500.1 amp. Whole car is filled with the bass I was missing at low volume crisp and loud at 3/4 volume with hardly any gain set on the amp.
Pros: Best <$300 sub I have ever had. Clear crisp bass.
Cons: Base of enclosure could be deeper to make it harder to rock around. But can be overcome with a wedge on front side.

Pros: Less than $200 and you definitely can't tell from the way it performs.
Cons: None so far
