Extron SF 26CT LP 6.5" LowProfile 2-Way Ceiling Spkrs, Complete Pair

The Extron SoundField® XD model SF 26CT LP is a low profile 6.5" two-way ceiling speaker featuring a 4.2" (107 mm) deep composite back can for use in restricted height plenum environments. The driver complement includes a 6.5" (165 mm) woofer coupled to a 3/4" (19 mm) ferrofluid-cooled dome tweeter. The SF 26CT LP offers both direct 8 ohm and 70/100 volt operation with a behind-the-grille, six position power selector switch. With high impedance taps at 8, 16, 32, and 64 watts, the SF 26CT LP is ideal for applications that require a high power distributed speaker system in plenum spaces that will not accommodate a taller back can.

The SF 26CT LP provides a wide and smooth frequency range of 85 Hz to 20 kHz and is engineered with a 95° conical dispersion that ensures excellent on and off axis voice intelligibility. A power rating of 130 watts continuous program also gives this speaker plenty of headroom for music reproduction in moderate to high output systems. 

Designed for Pro AV

The SF 26CT LP continues the new paradigm in speaker technology for pro AV applications that began wtih the Extron SF 26CT. With innovative materials, modular construction, and unique features, these 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 26CT LP is ideal for both single-trade and division-of-labor installations. The SF 26CT 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 driver assembly 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 driver assembly and grille.

Magnetically Attached Modern Looking Grille

The SF 26CT 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. A secondary punch-out allows easy daisy chaining from speaker to speaker when using conduit.

Opti-Torque Indicator Ring

The SF 26CT 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 screwdriver 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 26CT 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.
