Dynamic Balance Driver Technology: Polk Audio's patented Dynamic
Balance process allows Polk to design their drivers specifically for flatter
frequency response, revealing the sharpest details and a more lifelike
transparency, with absolutely no strain even at high volume. It's a bold, rich,
warm, and lifelike sound.
Time Lens Technology: The sophisticated laser alignment of the
"acoustic center" of the Blackstone TL tweeters with their accompanying drivers
results in far superior imaging. The acoustic centers of the tweeter and
mid-range woofer are aligned, creating a crisp accurate soundstage. The acoustic
centers of the tweeter and mid-bass driver are located in the same plane for
superior imaging, while the acoustic lens incorporated in the grille smoothes
the tweeter's frequency response.
3/4" Silk Dome Tweeter: The Polk Audio Black Stone TL2
center-channel speaker utilize a 3/4" silk dome tweeter for crisp, clear
imaging, and smooth response that's never tiring.
3-1/4" Composite Injection Molded Woofer: The Polk Audio
Black Stone TL2 center-channel speaker employs two 3-1/4" composite injected
molded cone woofers with Dynamic Balance driver technology (Polk's patented
transducer design process) that produces a flat frequency response, with sharp
detail, transparency, and the ability to play loud without strain.
Frequency Response: The speaker's overall frequency response
is 90-24,000Hz, and the -3dB frequency response is 125-20,000Hz.
Additional Speakers: The TL2 center-channel speaker will
require a powered subwoofer (107PSW111,
sold separately) for full-range sound.
Enclosure Type: The Polk Audio Black Stone TL2
center-channel speaker features a non-resonant composite enclosure with
time-aligned geometry, and PowerPort technology.
Curved Enclosure Design: The Polk Audio Black Stone TL2
speaker employs non-parallel surfaces that not only lead to a stronger, more
rigid and acoustically inert enclosure, but they also result in less audible
coloration from internal surface resonances.
Steel Reinforced: Extra-rigid steel plates reinforce the
curved enclosures of the TL2 center-channel speaker, resulting in an
acoustically inert enclosure free from internal resonances and any audible
coloration, for more lifelike audio detail.
Integrated Acoustic Lens: An innovative acoustic lens incorporated
into the grille produces a high frequency response so smooth that it delivers a
balanced, realistic performance. An acoustic lens is molded into the back of the
speaker grille and helps create imaging frequency balance previously impossible
in small high-performance loudspeakers.
PowerPort: The Polk Audio Black Stone TL2 center-channel
speaker utilizes Polk Audio's patented bass venting technology, for added
midbass response and increased efficiency. PowerPort technology decreases port
turbulence and virtually eliminates "port noise," for a massive 3dB boost in
High-Gloss Finish: The Polk Audio TL2 center-channel loudspeaker features a
durable, deep automotive-strength high-gloss finish that matches today's most
stylish flat-panel TVs. The TL2 center-channel is available in a high-gloss black
5-Way Binding Posts: The Polk Audio Black Stone TL2
center-channel is equipped with
one pair of 5-way binding posts to ensure a secure connection to many types of
speaker cables and connectors. The binding post terminals will accept banana
plugs (single or dual), pin-connectors, spade-connectors, and bare wire (18-12 AGW).
Rubber Feet: The Polk Audio TL2 center-channel features four integrated rubber feet
so you can sit the speaker on a stand or shelf securely.
Wall Mountable: The TL2 center-channel speaker features dual
single keyhole slots on the back of the cabinet for wall-mounting the speaker
without any additional wall-mount bracket (mounting screws not supplied). There
is also a 1/4"-20 threaded insert on the back of the loudspeaker for mounting
the speaker to the wall using an optional articulating bracket (sold
