Our take on the Infinity Reference R253

A room-friendly tower with a powerful punch

Music and movie lovers will find a lot to like in Infinity's Reference R253. This slender tower speaker uses Infinity's most advanced drivers to deliver rich, powerful, room-filling sound. Its sleek, contemporary cabinet houses dual 5-1/4" woofers for taut, well-defined bass, a 5-1/4" flat-piston midrange for superior clarity, plus a 1" dome tweeter for crisp, extended highs. The Reference R253's dynamic, full-range sound and small footprint make it great choice for both music and home theater systems in a medium-sized room.

High-tech CMMD™ drivers for exhilarating performance

Infinity Reference speakers owe their open, natural sound to Infinity's patented Ceramic Metal Matrix Diaphragm driver material. CMMD combines layers of ceramic with a stiff metal core for crystal-clear sonic performance. It's strong and durable, yet incredibly lightweight and responsive to the audio signal, providing the accuracy needed to hear your music just the way it was recorded.  

The R253's 1" CMMD dome tweeter delivers crisp, sparkling treble. Its Advanced Waveguide design provides better high-frequency dispersion for smooth, seamless sound across a wide listening area. You'll enjoy outstanding clarity and definition, even when listening in a less than an optimal location.

A  5-1/4" flat-piston CMMD midrange supplies the speaker's critical mid- and high-frequency sounds. Its unique flat cone design reduces sound diffraction to improve vocal and dialogue intelligibility. A dedicated sub-enclosure around the driver eliminates interaction with the woofers, further enhancing midrange clarity.

The speaker's tight, responsive bass comes courtesy of two Infinity 5-1/4" CMMD high-output woofers in a tuned-port enclosure. Infinity carefully computer-optimized the crossover network, as well as each driver's position within the cabinet to ensure the most  precise, natural, and stable imaging and soundstaging possible.

Build a complete Reference system

The Infinity Reference R253s will fill just about any room with powerful, well-defined sound. Use a pair to create a high-quality stereo system, or use them with Infinity's RC252 center channel speaker and RS152 surround channel speakers to create a stunning Reference home theater system. And don't forget to add the perfectly matched Reference SUB R10 powered subwoofer to get deep, accurate bass in the mix.

good for the price

Crutchfield Customer Review (What's this?)

I bought these on sale over some bookshelf speakers that were recommended to me because of space/money limitations. I wanted some nice floorstanding speakers for a 3.1 setup. This, coupled with the RC252 make a great 3 speaker set up. Only complaint is that sometimes the stereo (2 2253s) setting sounds better than the surround (3.1) for music. It makes it sound a little more muffled. Perform well without a sub, but I like more kick so I have a sub in addition to these guys.

Pros: Very sleek, optional dust screen, can handle lows pretty well without a sub.

Cons: Lack the clarity I was hoping for in a reference series speaker

Crutchfield Customer Review (What's this?)

Bought these after reading favorable review model above these. Mine were on sale and open box. Detail and imaging are great to the point Epos M5i and veleodyne sub are now boxed in storage. They are taller than expected but smaller foot print over Epos/stands combo. Used for music only others most likely need a sub (I do not).

Pros: Tweeter/midrange drivers are in optimal position due to tall cabinet. Floor standers, don't have to mess around with stands.

Cons: Not really con, but only available in one finish - black

Product Research


3-Way Speaker Design: The Infinity Reference series R253 floor-standing loudspeaker utilizes a three-way speaker design with a 1" CMMD tweeter that features an advanced image control waveguide, a 5.25" CMMD low-diffraction midrange driver, and two 5.25" CMMD high-output woofers for natural, balanced, and intelligible sound.

Advanced Image Control Waveguide: The R253's tweeter utilizes an advanced image control waveguide to deliver, more even high frequency response, no matter what part of the room you're in. The unique geometry of this waveguide delivers remarkable high frequency detail, imaging, and natural balance at nearly any listening position in a broad range of acoustic environments.

CMMD Technology: Infinity utilizes Ceramic Metal Matrix Diaphragm (CMMD) technology in the tweeter, midrange, and woofers that is much stiffer with more damping than standard metal speaker diaphragms.

  • For the tweeter, CMMD technology offers superior stiffness and damping compared to traditional metal domes, that provides a significant boost to the high frequency range.
  • For the midrange and woofers, CMMD offers exceptional pistonic operation over the entire usable range of the driver, completely eliminating unwanted coloration and distortion of the sound.

Low-Diffraction Midrange: The tower speaker's low-diffraction midrange driver reduces sound diffraction and provides better vocals with greater dialog intelligibility.

Bass Reflex Cabinet: The Infinity Reference series tower loudspeaker utilizes a bass reflex enclosure with two rear-firing ports for greater efficiency and bigger bass response. The Infinity R253 employs a extremely low resonance enclosure, so you hear the music exactly as it was intended. The R253 features a black wood grain vinyl cabinet that matches almost any decor. The speaker comes with a removable black cloth grille with a rigid plastic frame.

Dual Binding Posts: The Infinity Reference series floor-standing speaker features dual 5-way, gold-plated binding posts that can accept bare wire (up to 8AWG), spade-lugs, pin-connectors, and banana plugs (single or dual). The two sets of binding posts are shorted together by gold-plated jumpers. With the jumpers removed the R253 can be bi-wired or bi-amplified.

Rubber & Spiked Feet: The Infinity R253 floor-standing speaker features integrated rubber feet and comes with additional spiked feet. The rubber feet should be used on hardwood and tiles floors, while the spikes should be used on carpeted flooring. The spiked feet thread into the bottom of the integrated rubber feet of the speaker. The spiked feet add approximately 0.4375" to the height of the speaker.

Placement: For best results, place the speakers 6' to 8' apart and angle each speaker toward the listening position. Position each speaker so that the tweeter is approximately at ear level. Generally, bass output will increase as the speakers are moved closer to a wall or corner.
