Frequently Asked Questions
The KS118's cardioid is noticeably more effective at rejecting stage noise due to the larger driver size and more aggressive pattern shaping.
It’s more than a simple EQ; it subtly alters the driver’s excursion and amplifier response to extend the usable low-frequency range, though it does sacrifice a bit of maximum output.
It’s a Neutrik PowerCON cable, offering a secure, reliable connection that’s less likely to be accidentally pulled out during a performance – a smart detail for gigging musicians.
