I performed the measurements with the Klipsch The Nines Primary speaker (serial number 107128623160250). Before I started the testing, I installed the Klipsch Connect app on my iPad mini and paired it with the speaker with Bluetooth. I used the app to set the equalizer controls to Flat, the low-frequency equalization to Other, which is used for a free-space placement away from the room boundaries, and to turn off the Dynamic Bass function, which adjusts the low-frequency extension up or down as the output level changes.
The app identified the speaker’s firmware
