Transducers
Low Frequency 135 mm (5.25 in), woven-fiberglass cone with pure
butyl rubber surround with Weather-Edge frame
protection, high-temp fiberglass voice coil former, high-
temp voice coil wire, optimized cone geometry, linear
suspension spider, and FEA optimized motor structure.
High Frequency 19 mm (0.75 in) PEI diaphragm, low-viscosity ferro-
magnetic fluid, and lightweight Kapton™ voice coil
former.
Physical
Enclosure Material High Impact Polystyrene (HIPS), painted with highly-UV
resistant paint on white (-WH) version for maximum UV
fade resistance.
Grille Highly zinc-plated, finished in durable TGIC polyester
powder coating. MTC-25WMG-1 (&-WH) available
with Weather-Max™ multi-layer foam and tight-weave
mesh vapor barrier backing.
Installation InvisiBall wall-mounting system included. Two 6 mm
attachment points (on top and bottom) for optional
MTC-25UB-1 (&-WH) U-bracket. Secondary safety
attachment loop point on back panel.
Environmental IP-44 per IEC529 (IP-55 when installed with the
optional MTC-25WMG-1 WeatherMax™ grille and
either MTC-PC2 or MTC-PC3 panel cover.) Exceeds
MilSpec 810 for humidity, salt-spray, temperature &
UV. Passes MilStd-202F for salt spray and ASTM G85
for acid-air plus salt spray. Optional MTC-25WMG-1
WeatherMax™ grille for breaking up driving rain and
for especially difficult environments.

¹ In half-space (on-wall, 2pi)
² At 8Ω setting. Continuous Pink Noise rating is IEC-shaped pink noise with a 6 dB
crest factor. Continuous Program Power is defined as 3 dB above the Continuous
Pink Noise Rating and is a conservative expression of the system’s ability to handle
normal speech and music program material.
