The sub-GHz frequency bands, which normally span from 433 MHz to 915 MHz, are where LoRa technology operates. It combines low power consumption with long-range communication through the use of spread spectrum modulation. However, communications at frequencies lower than 10 kHz cannot be sent using LoRa. The technology's performance characteristics are tuned for the MHz range, where it is intended to operate. LoRa was not designed to operate at 10 kHz, so attempting to do so might not produce accurate results.

LoRa operates with a carrier frequency of roughly 900MHz. (It varies depending on which part of the world you are operating.) I see no reason why you could not transmit signals having a bandwidth of 10kHz.
