Design Notes

61NPM was developed for all applications where compact and lightweight t mid-woofer is required.
The driver delivers very good performance in mid-frequencies, with a good extension into the low frequencies.
Neodymium based magnetic circuit was optimized to deliver the highest level of performance.
Lightweight paper cone with glass fibers is attached to “M” roll fabric surround. It provides great combination that delivers very good performance across wide range of frequencies.
Our newly designed basket was structurally reinforced and supports the magnetic structure with ease. Furthermore, the driver sports front and rear gaskets, thus you can mount it into the baffle as front or rear mount.

Enclosure Recommendations

Recommended enclosure alignments (bass reflex):
- 6 liters tuned to 106 Hz: high output, strong mid-bass, reduced excursion; -3 dB approx. 98 Hz, HP filter 98 Hz
- 6 liters tuned to 93 Hz: balanced response, general-purpose (recommended); -3 dB approx. 86 Hz, HP filter 83 Hz
- 8 liters tuned to 81 Hz: extended low-frequency, requires HP filter protection; -3 dB approx. 69 Hz, HP filter 69 Hz
