Extron SM 28T (part number 60-1309-12) — a two-way surface mount speaker pair finished in black, built for 70V or 100V constant-voltage distribution as well as 8 ohm direct.

The SM 28T carries an 8-inch long-throw woofer with dual tuned bass reflex ports and a 1.1-inch silk dome tweeter in a molded plastic trapezoidal enclosure. A five-position rotary tap selector reaches up to 64 W per speaker and is adjustable through the front grille, so a tech does not need to pull the speaker off the wall to change taps. Like the rest of the SpeedMount line, the mounting plate and cable termination can be completed by a low-voltage contractor during rough-in, with the speaker added later by the AV integrator.

Key Capabilities

Five power taps up to 64 W for 70 V or 100 V distributed audio
90 W continuous pink noise, 180 W continuous program power handling per pair
Frequency range of 59 Hz to 22 kHz (-10 dB, full space)
Grille-accessible tap selector simplifies large-scale zone tuning
Included 0° mounting plate plus 10° mounting adapter for angled aiming

Where It Is Used

The SM 28T suits paging and background music zones in classrooms, retail spaces, and multi-room facilities where several speakers share a single 70V or 100V amplifier run and individual level control per zone is needed.

Specifications at a Glance

8-inch woofer, 1.1-inch silk dome tweeter, 8 ohm direct or 70V/100V operation
2.0 kHz crossover frequency
16.50" H x 11.50" W x 7.80" D with 0° mounting plate attached
12.8 lbs per speaker with mounting plate; 33 lbs shipping weight per pair
5-year parts and labor warranty
