Go larger to go lower
If you are looking to localize low frequencies, you need a large array. That's just physics. But if you are not in the market for a long-range Star48 array, consider the robust Ring72. With a 120 cm diameter, it is capable of measuring as low as 105 Hz without being especially massive.
