No Compromise 12" Woofer

	Aluminium die-casting basket
	Patented design with rear vented voice coil: higher maximum power capacity 1000 Watts, lower power-compression
	Extraordinarily low-distortion bass-reproduction through extremly long linear voice-coil excursion
	Double side coated diaphragm: very low distortion, high degree of self damping, weather-proof
	Exceptionally good ratio between inner and outer diameter
	Maximum sound pressure level 125 dB

Facilities for Different Operation Modes

	Integrated passive crossover, 12 dB/oct. slope
	Possibility to switch over to external active mode
	Optimum low frequency extension for the Klein + Hummel Pro X 5, Pro X 6, Pro X 12/80 and all RX models

Sophisticated Enclosure Construction

	Poor of resonances by means of numerous wall bracings: - dry, impulse-proof bass sound - linear, level-independant frequency response - higher sound pressure level
	Poor power compression by generously dimensioned bass reflex ports
	Protection grille front side with acoustic foam
	Well transportable through 2 big sized metal grip caps and put back rear wall
	Adaptor for adjustable stand pipe Klein + Hummel SR 21
