Product description

The right HEDD Type 20 is a three-way active studio monitor well suited for compact recording studios, home studios, small mastering studios, or anywhere else that requires full-range midfield monitoring. The design combines a 7" Ultra Honeycomb Composite (UHC) woofer, a 4" midrange driver (also UHC), and a HEDD Air Motion Transformer (HEDD AMT) tweeter to provide an accurate frequency response reaching all the way down to 32 Hz and up as high as 50 kHz. With a pair of HEDD Type 20 monitors, you can achieve a maximum SPL of 120 dB.The strong, rubber-coated cabinet houses not only the drivers, but also three 300W Class-D ICEpower amplifiers. The rear panel features balanced XLR and unbalanced RCA inputs, high- and low-shelf potentiometers, and a gain control. This monitor is universally powered for compatibility anywhere in the world. Furthermore, the monitor supports HEDD Bridge input cards (available separately) for digital connectivity, including cards with Dante, AES67, AES3, and USB 2.0 connectors.
