Technical Summary
The 103FINDX8-583B is a 10-inch ferrite mid-woofer designed for professional 2-way PA speaker systems, compact touring cabinets, and permanent installation enclosures crossed to a compression driver or horn. It features a carbon fiber paper cone, fabric surround, Nomex spider, and a 63.5mm copper voice coil on a Titanium Imide Laminate (TIL) former, providing high thermal stability for sustained high-power operation. Sensitivity is 95 dB (1W/1m). With a Qts of 0.29, this driver uses a low Qts, high motor strength design optimized to maintain consistent performance at high drive levels, with controlled excursion and reduced thermal compression during long-term operation.
The 103FINDX8-583B handles approx. 250 W AES and 500 W continuous power, with a peak SPL of 119 dB at 1 metre (AES) and 122 dB at continuous rated power. A high-pass filter in the 45-60 Hz range is recommended depending on alignment. The operating bandwidth is approximately 65-1,000 Hz, with cone beaming onset near 1,039 Hz and inductance rolloff near 1,637 Hz; a crossover to a compression driver on horn at 800 Hz to 1.5 kHz is required. Third or fourth-order crossover slopes are recommended to control directivity above 1,039 Hz.
This driver is suited for compact single-driver vented 2-way PA touring cabinets; 2-way portable and installed PA enclosures for live sound and fixed venue reinforcement; stage monitor wedges crossed to a compression horn at 1 kHz; and installed permanent-mount 2-way enclosures in venues where a dedicated subwoofer is available. The high motor strength, TIL former, Nomex spider, and fabric surround prioritize consistent output and thermal reliability during sustained high-power operation.

Recommended enclosure volumes are simulated results. For best enclosure volumes and tuning, we recommend secondary simulation and careful evaluation. Several rounds of samples and fine-tuning may be required for optimal results.
Enclosure Recommendations
Recommended enclosure alignments (bass reflex): - 30 liters tuned to 59 Hz: high output, strong mid-bass, reduced excursion; -3 dB approx. 54 Hz, HP filter 51 Hz - 35 liters tuned to 51 Hz: balanced response, general-purpose (recommended); -3 dB approx. 43 Hz, HP filter 41 Hz - 45 liters tuned to 45 Hz: extended low-frequency, requires HP filter protection; -3 dB approx. 38 Hz, HP filter 33 Hz
