If you are looking for something with a serious amount of power then the Electro-Voice ETX Dual ETX12P & ETX18SP Power Pack should give you everything you need in one straightforward package. Aimed at professional DJs and live performers, the 7600W Active Sound System delivers a fantastic sound with any source material, even at high SPLs, which makes this the perfect setup for medium to large venues where loud volume levels and high fidelity reproduction are both desirable and necessary. Those on a more conservative budget would do well to consider a pair of Electro-Voice ZLX-12Ps. These are the best selling pro audio speakers in the world and they are currently on offer with an £88 Cash Back deal on every pair sold from now up until the end of January 2017. Featuring the very latest in DSP technology, these speakers can adapt to their environment and adjust to any source program material with a simple range of useful parameters that are easy to access thanks to a cleverly designed yet deceptively simple interface. Offering incredible clarity with an enormous sound, the ZLX range also features convenient level meters and a separate amp control for quick and easy gain structure.
