Tunable down-hole stimulation arrays feature closed-loop control of spatial arrays comprising several connected stimulators. Each stimulator is responsive to a timed activation signal. Stimulators periodically transmit bursts comprising a plurality of vibration frequencies, each burst having an adjustable power spectral density (PSD) that is tunable via an adjustable rebound cycle time. Rebound cycle times also affect vibration interference among array stimulators, while simultaneous or sequential timed activation signals from a programmable controller affect directional propagation of combined vibration wave fronts from an array. Stimulator PSD's are adjusted for resonance excitation and fracturing of adjacent geologic materials. Closed-loop feedback control incorporates backscatter vibration from stimulated geologic material. As fracturing proceeds to smaller (proppant-sized) fragments having higher resonant frequencies, PSD's are up-shifted, increasing relative power in higher vibration frequencies. Progressive geologic stimulation is optimized, with inherent potential for plain-water fracs completed with self-generated proppant.
