Overview: The Polk Audio Black Stone TL3 series
center-channel speaker (TL3)
features new innovations specifically designed to enhance the compact speaker's
performance. The Black Stone TL3 is a two-way center-channel loudspeaker with a
Dynamic Balanced ring-radiator tweeter and dual 3-1/4" Dynamic Balance
aerated polypropylene woofers inside a
bass-reflex enclosure with a bottom-firing port. The TL3 is equipped with 5-way
binding posts and offers various mounting options.
Note: The TL3 has an overall frequency response of 115 to
Hz and will require a powered subwoofer(107PSW111,
sold separately) for full-range
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" Ring Radiator Tweeter: The Polk Audio Black Stone TL3
series center speaker features a 3/4" ring radiator tweeter that is normally
found only on high-end loudspeakers. The 3/4" ring radiator tweeter offers
incredible accuracy and detail, so you music sound likes the artist intended.
3-1/4" Aerated Polypropylene Woofer: The Polk Audio Black
Stone TL3 series center speaker employs a 3-1/4" aerated polypropylene cone
woofer 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. The aerated polypropylene cone is lightweight, yet stiff and strong, with longer linear
excursion capabilities in a limited compact enclosure space, so it plays louder
with less distortion.
Optimized Linear Motor Structure: Engineered for better
compact speaker performance, Polk's OLM Motor Structure flattens the BL Curve,
making cone movement more efficient than previously possible, reducing
distortion and extending the small speaker's dynamic range right up into big
Frequency Response: The speaker's overall frequency response
is 90-31,000Hz, and the -3dB frequency response is 115-28,000Hz.
Additional Speakers: The TL3 center-channel speaker will
require a powered subwoofer (107PSW111,
sold separately) for full-range sound.
Enclosure Type: The Polk Audio Black Stone TL3
center-channel speaker features a non-resonant composite enclosure with
time-aligned geometry, and PowerPort technology.
Curved Enclosure Design: The Polk Audio Black Stone TL3
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 TL3 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 TL3 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 TL3 center-channel loudspeaker features a
durable, deep automotive-strength high-gloss finish that matches today's most
stylish flat-panel TVs. The TL3 center-channel is available in a high-gloss black
5-Way Binding Posts: The Polk Audio Black Stone TL3
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 TL3 center-channel features
three integrated rubber feet
so you can sit the speaker on a stand or shelf securely.
Wall Mountable: The TL3 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
