Hertz Cento 10" Sub, 4 Ohms
 
Powerful low bass form a compact enclosure is surely the holy grail for anyone looking to build a complete system on a budget. This 10" beauty has been designed to operate in a sealed enclosure of just 16 Litres. Capable of handling fast transients up to 600 Watts, the Cento CS 250 S4 is yet another example of how Hertz is rapidly rewriting the rules of car hifi.
