Extron SF 3CT LP 16W Black,White loudspeaker

Extron SF 3CT LP, 65 Hz - 20 kHz, 16 W RMS, 83 dB SPL, 8 Ω, 1.6 kg - 4" (10.2 cm) deep low profile composite back can for plenum environments
- 3" (7.6 cm) full-range driver with a tuned port
- Frequency range: 65 Hz to 20 kHz
- 165° conical dispersion
- 16 watts continuous pink noise, 32 watts continuous program
- 8 ohm direct or 70/100 volt operation on a 6 position, behind-the-grille selector

The Extron SoundField® XD model SF 3CT LP is a 3” full-range ceiling speaker featuring a 4" (10.2 cm) deep composite back can for use in plenum rated ceiling environments. This low profile speaker is ideal for ceiling installations with tight above-the-ceiling space issues, such as air handling ducts installed close to the ceiling. The SF 3CT LP offers both direct 8 ohm and 70/100 volt operation with a behind-the-grille, six position power selector switch. With 70/100 volt taps at 1, 2, 4, 8 and 16 watts, the SF 3CT LP will handle most distributed audio needs.

The redesigned 3” (7.6 cm) full-range driver features a wider and smoother frequency range of 65 Hz to 20 kHz and is engineered with an extremely wide and well controlled 165° conical dispersion. This design reduces beaming of mid and high frequencies directly under the speaker. Vocal intelligibility is critical for voice lift applications, and the SF 3CT LP provides excellent voice clarity. A power rating of 32 watts continuous program also gives this speaker plenty of headroom for music reproduction.

The Ceiling Speaker Reimagined

The SF 3CT LP represents a new paradigm in speaker technology for pro AV applications. We designed the SF 3CT LP from the ground up. With innovative materials, modular construction, and many other unique features, these new SoundField XD speakers provide significant savings and superior performance.

Plenum Rated Composite Enclosure

The ideal speaker enclosure needs to be constructed in such a way as to avoid internal standing waves and resonances in the enclosure itself. It should also be lightweight and fire tested for use in plenum air-handling spaces. We were able to achieve all of these requirements by injection molding the enclosure with a fire resistant composite material. The result is a rigid, acoustically damped, lightweight, plenum rated enclosure that is UL 2043 listed.

Supports Division of Labor and Single Trade

Shipped as a complete speaker assembly, the SF 3CT LP is ideal for both single-trade and division-of-labor installations. The SF 3CT LP speaker can be installed by a single contractor as a self-contained unit for retrofits and new construction. For larger projects with multiple trades, the speaker baffle and back can can be separated, allowing the rough-in contractor to install and fully terminate the back can. Once the job site is clean and secure, the AV integrator can then easily install the speaker baffle and grille.

Magnetically Attached Modern Looking Grille

The SF 3CT LP features a finely perforated round metal grille with a thin-edged rounded bezel for a refined appearance on the ceiling. The grille securely attaches magnetically to the baffle and quickly snaps into place. An optional square grille is available with the same finely perforated metal and thin-edged rounded bezel. This gives the owner, architect or interior designer an additional choice for matching the décor. The grille assemblies are white and can be painted to match the architectural elements of the environment.

Cable/Conduit Access Plate

The cable/conduit access plate is used to bring speaker cable into the enclosure, whether free-pulled or through flex conduit. The cable/conduit access plate has two punch-outs for ½” conduit, flex or screw clamp fittings. Two punch-outs allow easy daisy chaining from speaker to speaker. The cable/conduit access plate can be oriented for side mount or for top mount. The side mount orientation allows cable/flex/conduit to enter into the side of the enclosure, without increasing the overall 4" depth of the speaker. The top mount orientation allows for blind-mounting into drywall ceilings, keeping all cable/flex/conduit connections on the top.

Opti-Torque Indicator Ring

The SF 3CT LP features exclusive Opti-Torque™ indicator rings that provide a visual indication when the locking arm screws have been sufficiently tightened, preventing damage to the speaker caused by overtightening. As the installation technician tightens the locking arms, the red Opti-Torque™ indicator ring will audibly snap when the proper torque has been applied. As a visual indicator, the red ring drops down onto the screw-driver shaft, signaling to the technician that the proper force has been applied.

Modular V-Rail and Foldable C-Rings

To facilitate installation in a T-bar ceiling, newly redesigned modular V-rail and foldable C-rings are included with the SF 3CT LP. The V-rails have been designed as a two-part assembly that can be snapped together in the field. The foldable C-rings have been designed to make them easier to maneuver into place, even in blind-mount drywall applications. The installer snakes the C-ring up through the speaker cut-out, unfolds it, and positions it as needed. The result is a continuous metal support around the entire cut-out, resulting in a more secure attachment to the ceiling.

Reduced Shipping Weight and Storage Space

These innovations enable us to package each pair of SF 3CT LP speakers in a compact box measuring only 12.6"L by 12.5"W by 14.5"H. The box contains two speakers, two speaker grilles, two sets of modular V-rails, and two foldable C-rings. As such, the packaging is up to 40% smaller by volume than that of similar competitor products. This means that up to 65% more speakers can fit on a standard pallet. This reduces shipping and storage costs, especially in a bonded warehouse.

The packaged products weigh up to 20% less than similar products. But the greater savings comes in dimensional shipping weight, which can be up to 40% lower for both domestic and international shipping. Less weight means reduced shipping costs.
