Hi KPA friends,
got a pair of EV ZLX 12 in my studio. Have to say that I am very impressed as they are very light, do not hiss, no ventilator, sound very good at low volume and high volume. The guitar sounds through the KPA have all the balls and sparkle I need for my purposes (not metall player..). Also recorded music sound very pleasant. It come with a DSP that allows to adapt to different situations (as wedges, PA etc) and also can manipulate the frequencies a bit for different applications (playback, live, vocals, techno). Compared to my Behringer B212D they sound much better as there is more clarity and punch. The Bs sound very nasal in comparison. For 370 Euro per speaker I think it is a very good deal. Compared it in the shop also with some RCFs (more expensive) that I did not like at all (due to kind of mid focussed sound). Search completed successfully. Keep them.
Cheers Sacapuntas
