NANO K4 integrates the design philosophy of JBL 4200 Series, the most loved studio monitor by professional musicians in the late 1980s, and carefully positions its tweeter and woofer for aligned acoustic centers of low, mid and high frequencies. Image Control Waveguide technology from the flagship M2 master reference monitor is employed, to bring greater depth and subtle details to an even broader sweet spot.
NANO K4 is embedded with a Bluetooth modular and supports wireless connection with smart audio devices. An integral M8 threaded nut in the bottom allows quick mounting on a standard microphone stand. A 3.5mm jack connector is available on the front panel for plug-&-play of a monitor headphone (best with AKG K141 MKII reference headphone). Having its base cut into two planes, the monitor pair can stand straight up or tilt 12° backward.
NANO K4 steps out of line for its contemporary design: greyish brown cabinet, bright-colored cone surround on the front, music-themed silhouette on the rear. For easier control of the system, K4 has its power switch and volume control front accessible.
A combination of design, usability and performance, NANO K4 strives to bring you the monitoring experience beyond your expectation.
