The drivers are model CT 448 AS with a 1" screw on throat.
The diaphragms are 1 3/4", (44 mm) titanium material.
Rated at 35w rms and 80w peak power (1 kHz high pass crossover).
SPL 108 dB 1W/1M
Bandwidth 800Hz - 18 kHz (-3dB)
- The CT 448 AS is designed to an wide frequency range of 800 to 18 ,000Hz in a large format horn, high efficiency and high dependability.
- DIAPHRAGM A pure titanium diaphragm is employed in the CT 448 AS. This diaphragm ensures rapid sound wave transmission, extremely flat frequency response, little cone breakup, excellent transient response and high sound image definition.
- Deformation is prevented by a surround formed of a special diamond pattern. It also effectively prevents fatigue and rupture caused by an excessive input level.
- VOICE COIL For the voice coil, the CT 448 AS employs round-wound aluminum wire, insulated in high temperature compounds. This design provides an exceptionally high acoustic conversion efficiency. It is wound on a bobbin formed from a high-polymer compound having ideal heat resistance up to 752F (400C).
- MAGNETIC CIRCUIT The magnetic circuit includes a 60 oz ferrite magnet for a magnetic flux density of 1.8 Tesla meters. The magnetic gap is capped by a ring of pure aluminum to prevent an increase in impedance (and resultant distortion) at high frequencies.
- DESIGN A rear-compression mounting system is employed for the diaphragm and voice coil assembly. This assures enhanced clarity, for rear compression neatly avoids the resonance generated at the edge of the diaphragm. It also improves the phase uniformity of all frequencies, particularly highs, since they are emitted from virtually all points on the diaphragm. A phasing plug serves to eliminate phase disturbances at the throat region, for virtually flat frequency response.
