Transducers
Low Frequency 76 mm (3.0 in), woven-fiberglass cone with pure butyl
rubber surround with Weather-Edge frame protection, high-
temp Kapton ™ voice coil former, high-temp voice coil wire,
optimized cone geometry, linear suspension spider, and FEA
optimized motor structure.
High Frequency 13 mm (0.5 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-23WMG-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-
23UB-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-23WMG-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-23WMG-1 WeatherMax™ grille for breaking
up driving rain and for especially difficult environments.
Termination Screw-down terminal strip, zinc-plated copper based, nickel-
plated metal screws and washers. Accepts up to 9 mm
outside 4 mm inside open lugs (#6, #8, or #10 lug), plus
bare wire (up to 12 AWG / 2.5 mm2). Optional MTC-PC2
and MTC-PC3 protective panel covers available to provide
sealed entrance for additional weather protection.

1
Measured 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.
3
Calculated from sensitivity and power handling, exclusive of power compression, at
THRU setting.
4
Half-space (on-wall) averaged 100 Hz – 10 kHz, 2.83V.
5
Coverage angle (-6 dB) average between 1.5 kHz and 12 kHz.
6
For protection against driving below resonant frequency and to keep transformer out
of saturation.
7
Vertical orientation.
