The Polk Audio Signature S35 is a slim-profile, high-resolution centre channel speaker featuring a 25 mm Terylene tweeter and six 76 mm mica-reinforced polypropylene mid-range drivers. It tucks below a TV to provide bigger-speaker sound without blocking the viewing area or an IR remote.
This pre-owned speaker is in good condition in black, with no manual and no original packaging.
Aimed at home theatre enthusiasts who want intelligible dialogue in a compact footprint; or at listeners considering a pair for an unconventional speakers for a stereo setup, the Signature S35 focuses on clarity first, then adds surprising weight from its dual Power Ports.

Why Choose the Polk Audio Signature S35 Center Speaker?
The Signature S35 is designed for rooms where a tall, deep centre channel would sit in front of the screen or remote sensor.
• Unobtrusive Height: Just 105 mm tall so it can live under most televisions.
• Arrayed Midrange: Six small drivers spread dialogue evenly across the seating area.
• Extended Treble: Terylene dome supports high-resolution soundtrack detail.
• Useful Bass for the Size: Dual Power Ports add body without a bulky cabinet.
• Simple Matching: 8 Ω impedance and 20–150 W recommended power suit many AV receivers.
Audition the Polk Audio Signature S35 at our Lane Cove showroom to confirm its dialogue focus and slim-cabinet convenience.
Despite the low profile, the Signature S35 quotes a 53 Hz to 40 kHz frequency response and 88 dB sensitivity.
That combination keeps speech forward while still leaving enough bandwidth for music beds and effects when the speaker is paired with capable left and right channels—or used as part of a matching Signature system.
At 105 × 620 × 155 mm and 6.35 kg it is easy to position. For home theatre use it is a practical centre; if a the second cabinet is purchased, the same slim format can also serve an unconventional stereo arrangement where height is the limiting factor.

New, this speaker sat around A$390 locally, so an A$325 ask for a used one is on the sensible side rather than a bargain-basement steal. Against recent used asking prices that commonly cluster around A$290–A$470 once converted from overseas listings, A$325 looks fair-to-good if it’s clean, tested, and includes the grill and carton.
That’s a worthwhile buy because the S35 is a slim center that punches above its size, with clear dialogue, easy placement under a TV, and enough output to keep up in a modest home-theater setup. Polk’s Signature line has a solid reputation for value and an easy-going sound, so if the unit is genuinely tidy and the seller can demo it, this is a buy rather than a worry.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Polk Audio emerged in 1972 from the inventive spirit of three Johns Hopkins University graduates—Matthew Polk, a physics major, George Klopfer, and Sandy Gross—in Baltimore, Maryland. What began as a modest venture building public address systems for local events evolved into a dedicated speaker company after an initial contract fell through, leaving the founders to sell their redesigned cabinets directly. Fueled by passion for music and hi-fi innovation, they secured Small Business Administration loans, relocated operations, and rapidly scaled production, hitting $1 million in revenue by 1976 and earning a spot on Inc. magazine's list of America's fastest-growing private companies.
The brand has long focused on loudspeakers as its cornerstone, pioneering models like the Monitor 7 series for balanced dynamics, deep bass, and high-volume performance that bridged European refinement with American power. Polk expanded into automotive audio through partnerships like MOMO in 1999, while maintaining a core lineup of home speakers, including innovative SDA technology for enhanced soundstaging. Though not delving into amplifiers, turntables, DACs, headphones, or cables, their emphasis remains on reliable, high-fidelity transducers engineered for generations-spanning accuracy.
Polk Audio holds a solid mid-tier position in the hi-fi market, prized by enthusiasts for value-driven performance sold through specialty stereo shops and big-box retailers like Best Buy. Once publicly traded on NASDAQ in 1986 before going private in 1999, the brand now operates under Sound United, upholding its legacy of accessible excellence without chasing ultra-high-end exclusivity or vintage obscurity.
