JL Audio TwK-88 System Tuning DSP is an 8-channel digital signal processor designed for precise multi-way system tuning in high-end automotive audio builds. Using JL Audio’s TüN™ software, the TwK-88 provides adjustable crossover filtering, time alignment, phase control, parametric EQ, input routing, and output assignment to optimize stage, imaging, and tonal balance.
Inputs include analog RCA and high-level speaker signals, with flexible input summing for OEM integration. Eight assignable RCA outputs enable complex 2-way, 3-way, 4-way and subwoofer configurations with amplifier-driven systems. Optional DRC controllers (sold separately) allow real-time recall for presets, sub level, and master level adjustments.
