The Extron SoundField XD model SF 26CT LP is a low profile 6.5 -inch two-way ceiling speaker featuring a 4.2 -inch (107 mm) deep composite back can for use in restricted height plenum environments. The driver complement includes a 6.5 -inch (165 mm) woofer coupled to a 3/4-inch (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 degrees 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. The SF 26CT LP continues the new paradigm in speaker technology for pro AV applications that began with the Extron SF 26CT. With innovative materials, modular construction, and unique features, these SoundField XD speakers provide significant savings and superior performance.
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. Extron was 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. 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 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. 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 decor. The grille assemblies are white and can be painted to match the architectural elements of the environment. 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 1/2 -inch conduit, flex, or screw clamp fittings. A secondary punch-out allows easy daisy chaining from speaker to speaker when using conduit. 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. 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.
