Closed box type of our 180 mm bass midrange driver with concave ceramic dome of 130 mm diameter. High loss rubber surround and aluminum voice coil former. Perfect choice for 2-way systems as bass-midrange driver or high quality 3-way systems as bass unit. Very high resolution and very good dispersion up to 4 kHz.
The ultra hard ceramic dome material moves like a piston within the linear frequency band of 29 Hz to 4.0 kHz. The high internal sound velocity leads to very low distortion and virtually no coloration.
