Our take on the Infinity Primus 253BK

The Infinity Primus P253BK's clean styling and dynamic performance make it a great addition to any home audio system. Use a pair of these speakers for stereo listening, and they'll create a large "sweet spot" — you'll enjoy warm sound throughout your entire room. Or make them a part of an Infinity Primus home theater setup for high-impact movie sound effects. Either way, you'll experience precise imaging and a wide soundstage.

A great blend of style, performance, and value

The Infinity Primus P253BK's clean styling and dynamic performance make it a great addition to any home audio system. Use a pair of these speakers for stereo listening, and they'll create a large "sweet spot" — you'll enjoy warm sound throughout your entire room. Or make them a part of an Infinity Primus home theater setup for high-impact movie sound effects. Either way, you'll experience precise imaging and a wide soundstage.

Designed and engineered for high-quality sound

The P253BK owes its performance to Infinity's exclusive Metal Matrix Diaphragm™ speaker material. This material uses a stiff metal core to add rigidity to the drivers, for clear, accurate sound. Two 5-1/4" woofers dish out detailed lows and mids, and a 3/4" tweeter produces highs with sparkling clarity. And the speaker's high sensitivity means that you won't strain your amp when you crank up the volume.

Build your own Primus system

A pair of the Infinity Primus P253BK towers will fill just about any room with dramatic, well-defined sound. Match them up with other Primus speakers, plus an Infinity powered subwoofer for deep, accurate bass, and create a stunning home theater system.

Recommended center channel: Infinity Primus PC250, PC251, PC350, or PC351.
Recommended surround speakers: Infinity Primus P153.
Recommended powered subwoofer: Infinity PS38 or PS212

Very good speakers



Great value

Eric from North Dakota on 1/27/2016

Crutchfield Customer Review (What's this?)

I bought a pair of these on sale for an old Kenwood stereo in the den and the sound is outstanding for a speaker at this price point. It is enjoyable to listen to all my LP's again given how good these speakers sound.

Pros: Great price and great service from Crutchfield

Cons: None, just wish I would have ordered them sooner

Perfect for home theater systems

Scott from wallingford, CT on 1/19/2016

Crutchfield Customer Review (What's this?)

I am using these towers with a Yamaha RX475 and they deliver terrific clear sound. They are coupled with an Energy subwoofer, Bose center channel and JBL satellites. The highs are crisp and balance out well with everything. I am completely satisfied with this purchase. Crutchfield is a quality organization that delivered what they promised, when they promised.

Pros: Plenty of power and sharp highs.

Cons: None/ZERO

Pros: everything, and the fact they were on sale was even better.

Cons: none

What I've come to expect from Crutchfield

Jim V from California on 3/1/2015

Crutchfield Customer Review (What's this?)

In 20 years of buying from Crutchfield I have never been disappointed. Quality gear at reasonable prices. I use these speakers for my 2 channel home stereo system in a large family room. They have excellent clarity and sound in all frequency ranges and compared to the 70s vintage Infinity speakers they replaced, they are wonderful. My only disappointment was the "Made in China" labels. I guess it is a sign of the times. We all better start learning Mandarin.



they fit in with my set just right

Fast Delivery, very easy to hook up, and the sound with these speakers it made my whole surround sound even better.



Well worth the $$$

RayO from Greeneville, Tennessee on 11/20/2014

Crutchfield Customer Review (What's this?)

I bought these to go along with the Infinity sub for my bedroom sound system and it is perfect. I use it for the sole sound system for the TV and all music.

Pros: Great sound at any volume

Cons: Does not produce much bass without the sub, but not too bad for a bedroom.

Crutchfield Customer Review (What's this?)

Looks good, not much floor space, CRYSTAL CLEAR SOUND, really efficient meaning plenty of sound at low volume settings. Need a Sub-woofer to fill out the low end.

Driver Technology

Metal Matrix Diaphragm (M.M.D.): Derived from the C.M.M.D. material used in Infinity's flagship Cascade series, M.M.D. features a stiff aluminum core, anodized on both sides for increased strength and rigidity. M.M.D. transducers conduct sound faster than paper, polypropylene, and Kevlar, pushing unwanted resonances beyond the operating range of the transducer. M.M.D. drivers deliver crystal-clear, distortion-free sound from dynamic digital sources, even at high listening levels.

Dual 5-1/4" Woofers: The dual 5-1/4" M.M.D. cone woofers offer extremely accurate midrange response for cleaner, more realistic sound. For a smoother response and improved durability, the woofers use rubber surrounds.

3/4" Tweeter: The speaker has a 3/4" M.M.D. dome tweeter that offers superior stiffness and damping compared to traditional metal domes.

Acoustical Waveguide: The P253's tweeter utilizes an acoustical waveguide to deliver, more even high frequency response, no matter what part of the room you're in.

Precision Crossover: Network: The speaker features a 2-way crossover system with crossover frequency at 2500Hz. The crossover has a 24dB/octave slope.

Enclosure Design

Wood Grain Vinyl Cabinet: The Infinity P253 features a black wood grain vinyl cabinet that matches almost any decor.

Bass Reflex Design: The Infinity Primus tower loudspeaker utilizes a bass reflex enclosure with a front-firing port for greater efficiency and bigger bass response.

Low Resonance Enclosure: The P253 employs a extremely low resonance enclosure, so you hear the music exactly as it was recorded.

Grille: The speaker comes with a removable black cloth grille with a rigid plastic frame.


5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.

Color-Coded: The speaker's binding posts are color-coded (red/black) for easy identification between positive and negative.

Mounting Options

Outboard/Inboard Feet: The speaker comes assembled with attractive silver outboard feet. If desired, you can replace them with the supplied, less visible, black inboard feet. The feet can be changed with the use of a handheld Phillips-head screwdriver. The overall width is approximately 1" less, and the overall height is approximately 1/4" less when the black, inboard feet are used, compared to the outboard feet.

2 questions already asked

You know what thats a good qustion. And to be honest Im not too sure about that. But you can try the newer model infinity primus 353. [ Luis A.  Dec 27, 2015 ]
A pair of infinity floor standing speakers id reasonably good for a home, so for that price you can get good sounds output in your home. [ JAINARAINE  Dec 17, 2015 ]
Yes, very good and pretty ?????????????????? [ Andrea Maria  Dec 17, 2015 ]
I would think so from using them on higher volumes with my 35 watt per channel receiver but have no experience with playing instruments along with them. The speakers are bright and dynamic and should workout fine [ Chris  Dec 17, 2015 ]
Shawn, I wold think so but I don't crank my speakers up or use them in this context. I do feel these are quality speakers. Good luck. [ RC  Dec 17, 2015 ]
I think it is each. They are good speakers. [ VICTORIA  Dec 18, 2014 ]
The text on the product page says, "Your price: $149.99 each". That's each speaker, not each pair. [ DONALD B  Dec 17, 2014 ]
Just for one [ Joseph  Dec 17, 2014 ]
These do not come in a set. The price is for each individual speaker. They do make a really nice surround speaker; I have two of these in the rear, P363 in front, P351 in center and a 12" sub. The sound is great, puts you right in the middle of the action. This is can be more affordable if you get two at a time, when they come on sale. [ James  Dec 17, 2014 ]
The price is for one speaker. However it may seem expensive but I promise you it is well worth your money! I've had plenty of surround system packages from Walmart and Kmart and the sound and realism is lacking. IN my opinion Infintiy is like a generic brand in comparison to Boston Acostic and some of the other top brands but their craftsmanship and quality are still amazing. I purchased a Dennon Reciver it is a 7.2 channel. I'm using all infinity speakers and it was more affordable and still amazing! You can start with a pair and than add on. I run 2 floor speakers for my mains and Im using 4 bookshelf speakers for my surround and rear surround I also have a center channel and a powered sub woofer I still have the option to add another powered sub just haven't done it yet [ MIGUEL D  Dec 17, 2014 ]
