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.
1/2" Silk Dome Tweeter: The Polk Audio Black Stone TL1 utilizes a 1/2"
silk-polymer dome tweeter for crisp, clear imaging, and smooth response that's never
2-1/2" Long-Throw Woofer: The Polk Audio Black Stone TL1 employs a
2-1/2" composite long-throw 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.
Frequency Response: The overall frequency response is
120Hz to 22kHz and the -3dB frequency response is 135Hz to 20kHz.
Additional Speakers: The TL1 satellite speaker will require
a powered subwoofer (107PSW111,
sold separately) for full-range sound. You can also add addition TL1 series
speakers for 2.1, 3.1, 5.1, 6.1 and 7.1 channel home theater configurations.
Enclosure Type: The Polk Audio Black Stone TL1 features a non-resonant
composite enclosure with time-aligned geometry and an aperiodic-tuned rear port.
Curved Enclosure Design: The Polk Audio Black Stone TL1 satellite
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.
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 satellite speakers.
Aperiodic-Tuned Rear Port: An aperiodic-tuned rear port enables better
blending with a subwoofer. This design combines the bass extension of an
acoustic suspension enclosure with the mid-bass boost of a ported enclosure by
controlling airflow through the port for better extension without distortion.
High-Gloss Finish: The Polk Audio TL1 satellite speaker features a
durable, deep automotive-strength high-gloss finish that matches today's most
stylish flat-panel TVs. The TL1 is available in a high-gloss black or white
5-Way Binding Posts: The Polk Audio Black Stone TL1 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
Rubber Feet: The Polk Audio TL1 features three integrated rubber feet
so you can sit the speaker on a stand or shelf securely.
Wall Mountable: The TL1 satellite speaker feature a single keyhole
slot 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 separately).
