This new version of the IN-8 is part of Kali’s 2nd Wave of loudspeakers. A new amplifier platform allows for 12 dB less self noise, while increasing max SPL by 3 dB. The tuning has been refined for smoother HF response, and the boundary EQs have been updated to reflect common real-world use cases. Physical improvements include lighter transducer cones for better transient response and upgraded cabinet construction for greater reliability.
The IN-8 features an 8-inch woofer, a 4-inch mid-range driver, and a 1-inch soft dome tweeter. The mid-range driver and the tweeter are coincident, meaning that they share the same acoustic center. You might have heard the terms “coaxial” or “concentric” to describe this arrangement. Those terms are technically correct as well.
Because of the coincident placement of the mid-range and tweeter, and the crossover of the woofer to the mid-range (330 Hz,) the IN-8 is an acoustic point source. This gives it an ideal directivity characteristic for a studio monitor. You will be able to hear a very lifelike stereo image, with details placed clearly and consistently. Off-axis lobing that is unavoidable in a 2-way system is virtually eliminated with the IN-8.
Substantial work was done to optimize the mid-range driver not only for its own acoustic performance, but also for its role as the waveguide for the tweeter. The shape is very precise to allow for controlled directivity at mid range to tweeter crossover, ensuring accurate summing both on- and off-axis. Excursion on the midrange is limited to less than 1mm peak to peak, so that the oscillation of the mid-range does not have a negative effect on the tweeter.
