H1212-06 27TBFC/G
27TBFC/G is a High Definition metal dome tweeter with a wide, soft polymer surround and a rear chamber.
Aluminium/magnesium alloy diaphragm with pistonic behaviour throughout the audible frequency range, resulting in a good dispersion also above 10kHz.
A Hexagrid protects the diaphragm, and supports a phase plate which compensates for a slight axial roll off towards 20 kHz.
Sonomax surround for low resonance and excellent mechanical linearity.
Voice coil windings immersed in magnetic fluid increase short term power handling capacity and reduce the compression at high power levels.
Stiff and stable rear chamber with optimal acoustic damping allows the tweeter to be used with moderately low crossover frequencies.
Precision moulded chassis from glass fibre reinforced plastic, and its front design offers optimum radiation conditions.

Specifications
*IEC 268-5, via High Pass Butterworth Filter 2500Hz 12 dB/oct. SEAS reserves the right to change technical data.
Dimensions
L18RNX/P is a 6,5” High Fidelity woofer with an injection moulded metal chassis, intended for bass reflex and transmission line designs.
Stiff, yet light aluminum cone and low loss rubber surround show no sign of the familiar 500-1500 Hz cone edge resonance and distortion assosiated with soft cones.
Large magnet system gives good transient response, and the bumped back plate together with the very long, and light weight copper clad aluminum voice coil allow for extreme coil excursion with low distortion.
Extremely stiff and stable injection moulded metal basket, keeps the critical components in perfect alignment.
Large windows in the basket both above and below the spider reduce sound reflection, air flow noise and cavity resonance to a minimum.
Frequency response
The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 12L closed box. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infinite baffle based on the parameters given for this specific driver. The impedance is measured in free air without baffle using a 2V sine signal.
