TK 181

is a 18” single sub-woofer in a system of “Back Road Horn” designed to play shocking and deep low pitched frequency from 4” (100mm) titanium driver and powerful magnet. It expresses intensive power in a concert hall and club requiring the extreme-level base. Moreover, a 460mm specially-coated unit remains intact without any transformation after a long time and is designed not to be damaged during the powerful low-pitched sound playing.
