System Features
Polk Audio Blackstone TL150 Five Speaker System: The Polk Audio Blackstone TL150 high-performance
five speaker system features 4 matching satellite loudspeakers and a horizontal
center-channel speaker. The Polk Audio Blackstone
TL150 system offers a compact, high-performance solution for your home theater,
music listening, or gaming needs. Plus you can add individually available,
perfectly timbre-matched Blackstone TL speakers (107TL1B, sold separately) to
expand your home theater experience into 6.1, 7.1, or 9.1 channels.
Note: The TL150 five speaker system has an overall
frequency response of 120 to 22,000 Hz and will require a powered subwoofer
(sold separately) for full-range sound.
Driver Technology
Polk Audio Black Stone TL Series: The Polk Audio Black Stone
TL series loudspeakers (TL1) feature new innovations specifically designed to
enhance compact speaker performance. The Black Stone TL1 series speaker is a
two-way satellite loudspeaker utilizing a bass-reflex enclosure with a
rear-firing port. The TL1 series loudspeakers are equipped with 5-way binding
posts and offer various mounting options.
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.
Drivers: The Black Stone TL1 satellite & center-channel speakers
feature a two-way design.
- 1/2" Silk Dome Tweeter: Each Polk Audio Black Stone TL1
satellite & center-channel loudspeaker utilizes a 1/2"
silk-polymer dome tweeter for crisp, clear imaging, and smooth response that's never
tiring.
- 2-1/2" Long-Throw Woofer: The Polk Audio Black Stone TL1
satellite loudspeakers use a 2-1/2" composite long-throw cone woofer, while
the TL1 center-channel employs dual
2-1/2" composite long-throw cone woofers. Each long-throw woofer utilizes
Dynamic Balance driver technology (Polk's patented transducer design
process) to produce a flat
frequency response, with sharp detail, transparency, and the ability to play
loud without strain.
Frequency Response: The overall frequency response of each
satellite loudspeaker is 120Hz-22kHz and the -3dB frequency response is
135-20kHz. The overall frequency response of the center-channel speaker is 95Hz-22kHz and the -3dB frequency response is
125-20kHz.
Enclosure Design
Enclosure Type: The Polk Audio Black Stone TL150 speaker
system 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 speakers and center-channel speaker employ 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 speakers and
center-channel speaker feature a durable, deep automotive-strength high-gloss
black finish that matches today's most stylish flat-panel TVs.
Connections
5-Way Binding Posts: The Polk Audio Black Stone TL150
speakers are 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).
Mounting Options
Rubber Feet: The Polk Audio TL1 satellite & center-channel
speakers feature integrated rubber feet
so you can sit the speaker on a stand or shelf securely.
Wall Mountable: The TL1 satellite & center-channel speakers feature keyhole
slots on the back of the cabinet for wall-mounting the speakers without any
additional wall-mount bracket (mounting screws not supplied). There is also a
1/4"-20 threaded insert on the back of each loudspeaker for mounting the speaker
to the wall using an optional articulating bracket (sold separately).
