2-Way Speaker Design: The Infinity Reference series R152 bookshelf
loudspeaker utilizes a two-way speaker design with a single 1" CMMD tweeter
an advanced image control waveguide and one 5.25" CMMD high-output woofer
for natural, balanced sound.
Advanced Image Control Waveguide: The R152'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 and woofer 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 woofer, CMMD offers exceptional
pistonic operation over the entire usable range of the driver, completely
eliminating unwanted coloration and distortion of the sound.
Bass Reflex Cabinet: The Infinity Reference series bookshelf
loudspeaker utilizes a bass reflex enclosure with a rear-firing port for
greater efficiency and bigger bass response. The Infinity R152 employs a
extremely low resonance enclosure, so you hear the music exactly as it was
intended. The R152 features a black wood grain vinyl cabinet that matches almost
any decor. The speaker comes with a removable black cloth grille with a rigid
Binding Posts: The 5-way binding posts will accept bare
wire, pin connectors, spade connectors, banana plugs, and dual banana plugs. The
speaker's binding posts are color-coded (red/black) for easy identification
between positive and negative.
Mounting Options: The Infinity R152 comes with four self-adhesive
rubber feet for each speaker to help secure them in place to prevent slippage
and vibration. The rubber feet add approximately 0.1875" to the overall height
of the speaker. There are no threaded inserts or keyhole slots on the back panel
of the speaker for wall-mounting. However, you can use the optional PinPoint
heavy duty side-grip wall-mounting bracket system (121AM40B,
sold separately) to wall mount the speakers.
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.
