Notes: Kali's IN-8 is one of the most innovative studio monitors ever made. Combining the natural advantages of a 3-way design with hyper-realistic imaging of a co-axial mid-range and tweeter, it offers more transparency, lower distortion, and a soundstage that must be heard to be believed. … Read more
Power. Detail. Soundstage.
The IN-8 Studio Monitor is a speaker like no other. Using the same woofer and tweeter from Kali's celebrated LP-8, the IN-8 adds a midrange driver that surrounds the tweeter, and acts as its waveguide.
In doing so, both the tweeter and the woofer are unburdened; with a smaller workload, they are able to play more clearly and with less distortion.
The coaxial nature of the midrange and tweeter make the IN-8 an acoustic point source. Off-axis lobing is thereby eliminated, resulting in a stereo soundstage that presents the listener with a hyper-realistic level of detail.
All of this means that the IN-8 is extremely accurate and easy to mix on, and that mixes made on the IN-8 will transfer wonderfully to other systems.

The single most important aspect of a studio monitor is its accuracy. A good studio monitor should present the material it's playing faithfully, allowing you to make critical decisions that you know will translate to all the systems that your work will ultimately be played on.
Not only does the IN-8 do this, but its coincident architecture allows it to be more accurate than other speakers in a wider variety of challenging acoustic environments.
Rather than make our own claims about the accuracy of our speakers, we had them independently tested. You can find IN-8 test data below from both Pro Sound Testing and Audio Science Review. Please note that the data from Pro Sound Testing requires CLF Reader, which is a free program.
Because of the IN-8's coincident architecture, you may notice a dip between 8-10 kHz when measuring with a single stationary microphone. The dip is an on-axis diffraction artifact of the midrange baffle interface. It is evident in on-axis measurements, but not in total sound power. Perception of timbre should be neutral in most rooms. It is not recommended to apply room-correction EQs to the IN-8s based on single point static measurements.
You may have heard about the "hyper-realistic" imaging of the IN-8. What does that mean?
When you listen to a stereo set of speakers, you're hearing information about where instruments and players were placed when the material was recorded. Even with purely digital material, producers can manipulate physical locations of elements in the mix, and you will hear these on a stereo recording.
Not only does this allow producers to create interesting spatial effects, but it means that you can work faster and with more confidence. An accurate soundstage lets you "see" each element of the mix in front of you, so you can hear exactly what happens when you make changes.
2-way systems with good waveguides, like Kali's LP-6 and LP-8, do a good job at conveying this spatial information. However, because the tweeter and woofer on those speakers (and most studio monitors!) are separate, this information gets lost in the space immediately above and below the speaker. This means that at the listening position, you're not hearing the full stereo picture.
The IN-8 solves this problem. The tweeter and midrange share an acoustic center, and the woofer is crossed over at 330 Hz, so the distance between the woofer and midrange is well under a quarter wavelength at the crossover point. This means that the IN-8 is acoustically a point source. As such, it has the same excellent directivity that the LP-6 and LP-8 have at their sides in a full 360 degrees around the speaker. You're hearing all of the spatial information at the listening position, so the soundstage that you hear will have every detail that's present in the mix.
The IN-8's total harmonic distortion is less than 1.4%, which is exceptional. This is the result of unburdening both the woofer and the tweeter, so that both are doing less work. The woofer is crossed over at 330 Hz, a full 2.5 octaves lower than on the LP-8.
