27TDF H1211 27TDF is a High Definition precoated fabric dome tweeter with a wide, soft polymer surround.
Sonotex precoated fabric diaphragm with high consistency and excellent stability against variations in air humidity
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. Optimally damped cavity in the pole piece controls and slightly lowers the fundamental resonance.
The chassis is precision moulded from glass fibre reinforced plastic, and its front design offers optimum radiation conditions.

MCA15RCY H1262 MCA15RCY is a 15 cm (5’’) cone driver, developed for use as a high quality midrange unit. Classically coated paper cone gives a smooth extended frequency response with a controlled roll off. The large magnet system, together with the light cone give high sensitivity with low distortion and good transient response. 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 [Hz] The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 20L 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.
