Kali Audio IN-5

They’re three-way, which is good against comb-filtering in the midrange.

Bandwidth is 39-25kHz (-10 dB).¹

The port is tuned to 43Hz, which coincides with a low E on a bass.² ! [[ Kali_IN-5_03-.QalqEA7gg9Yfo6wg.xSUoN5aq2SlFBa.jpg ]]

On-axis (blue) and off-axis (green) isn’t terribly different, thanks to the concentric drivers.² ! [[ Kali_IN-5_05-84i8PjWAolBnWcCWvcjiMW4fLLi2OuFG.jpg ]]
