Hertz are on the money for slimline subs at the moment and now offers these ES F20.5 and ES F25.5 numbers to get those musical juices flowing.
Available in both eight- and 10-inch sizes, these can handle up to 500 watts at peak and only require a modest amp to get these punching well above their weight.
The sub itself is designed for supreme accuracy with the lows, while the box ensures the unit is well ventilated to keep cool under high audio pressure. Sound job all round then.
Priced from £89.99
