Design Notes

The 10NPM is a high efficiency, (95 dB 1watt / 1 meter) 10-inch mid bass woofer with incredibly linear frequency response characteristics, extreme high power handling capability while generating low harmonic distortion artifacts.-
The 10NPM uses a lightweight carbon fiber loaded cone assembly along with a precision double roll constant geometry surround. This combination provides remarkable strength, high efficiency and a excursion linearity of 15.4mm.

Magnetic Circuit
REDCATT engineers have developed a lightweight, inside-neodymium slug based magnetic circuit capable of delivering the highest level of performance providing a consistent, high integrity magnetic flux gap, ultra low distortion characteristic and high efficiency cooling system. The magnetic circuit design is optimized to generate the minimum amount of flux modulation, providing exceptional stability.

Technical Summary

The 10NPMX8-319 is a 10-inch neodymium pro mid-woofer designed for professional 2-way PA speaker systems, compact touring cabinets, and permanently installed enclosures crossed to a compression driver or horn. It features a carbon fiber paper cone, double-roll constant-geometry fabric surround, Nomex spider, and a 3-inch CCAW voice coil on a glass fiber former, driven by an inside-slug neodymium magnetic circuit designed for minimized flux modulation and high flux-gap integrity. Sensitivity is 95.07 dB (1W/1m). With a Qts of 0.33, 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 10NPMX8-319 handles approx. 200 W AES and 400 W continuous power, with a peak SPL of 118 dB at 1 metre (AES) and 121 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 1,018 Hz and inductance rolloff near 1,309 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 1,018 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 2-way enclosures where a neodymium motor's reduced weight is advantageous. The inside-slug neodymium magnetic circuit, CCAW voice coil, and glass fiber former provide a lightweight motor assembly and consistent high-efficiency output for demanding sustained-power PA applications.

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):
- 25 liters tuned to 64 Hz: high output, strong mid-bass, reduced excursion; -3 dB approx. 59 Hz, HP filter 56 Hz
- 30 liters tuned to 56 Hz: balanced response, general-purpose (recommended); -3 dB approx. 48 Hz, HP filter 46 Hz
- 35 liters tuned to 49 Hz: extended low-frequency, requires HP filter protection; -3 dB approx. 42 Hz, HP filter 37 Hz
