DEQX-Cal review
A Windows tool for precise DEQX speaker, room and subwoofer correction.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DEQX-Cal is DEQX Pty Ltd’s desktop measurement, analysis and configuration software for compatible DEQX processors. It is aimed at audiophiles and professional audio users working with active speakers, subwoofers or multichannel systems. Using calibrated microphones and test signals, it measures speaker and room response, analyzes timing and frequency behavior, and creates digital correction filters. Profiles are then uploaded to DEQX hardware, making the product a focused companion to a DEQX installation rather than a standalone room-correction application.
Pricing is handled through contact sales, so buyers should discuss the software alongside their DEQX processor requirements. The published deployment is Windows desktop; legacy documentation describes Mac use through Boot Camp or virtualization. Setup involves measurement, analysis and profile configuration, with ticket and documentation support available. DEQX also describes calibration assistance from DEQXperts, which may help users who want guidance through the measurement process.
Its strongest capability is the combination of calibrated measurement and FIR-based correction. DEQX-Cal can address unwanted resonances and reflections, linearize speaker behavior, correct timing, align subwoofers, and create convolution FIR crossovers for DEQX-Active systems. It also supports multichannel mastering and active-speaker configurations. Choose it when a DEQX processor installation needs detailed speaker, room and timing work in one workflow. Buyers without compatible DEQX hardware, or those seeking a platform-independent room-correction tool, should consider a different product.
