Celestion's K12H-200TC 8 ohm 12" full-range woofer is an excellent choice when space is at an absolute minimum. This woofer uses a dual cone, or whizzer cone, design improving the high frequency response well beyond that of a standard 12", eliminating the need for a tweeter and crossover. The primary cone handles low to midrange frequencies while the smaller secondary cone reproduces the higher frequencies. A pressure formed cloth dust cap reinforces the secondary cone for enhanced mid-band clarity.
