Design Notes
The 154FIND is a cost-effective solution for two-way and multi-way systems, together with subwoofers. It’s lightweight yet strong cone allows the magnetic circuit to be size optimized while delivering a seizable amount of sound pressure. With its high efficiency (97 dB 1watt / 1 meter) and high power handling capabilities, this woofer will excel in all applications with tight budgets. The cone shape and material was developed to extend mid-frequency response, making the woofer good choice for two-way and multi-way systems.
Power Handling
At the core of the 154FIND is its voice coil technology featuring a composite Polyimide former material capable of withstanding peak temperatures above 280°C. The winding with high temperature handling copper wire ensures the long life of the voice coil, without the costly service cycles.
The cone is also extensively treated to withstand harsh environments and high humidity. Metal parts in the speaker assembly are coated for extreme weatherization protection.

Technical Summary
The 154FINDX8-298 is a 15-inch high-output mid-woofer driver designed for professional 2-way and multi-way systems requiring high sensitivity (97 dB 1W/1m) and controlled low-frequency behavior. The driver uses a balanced motor-suspension design that provides good cone control while maintaining usable output across its operating bandwidth.
The driver is intended for use with high-power amplification (approx. 500 W AES / 1000 W continuous) and DSP control. A high-pass filter in the range of 24-36 Hz is recommended depending on enclosure tuning, along with proper limiting to manage thermal and mechanical stress. Typical operating bandwidth is 31-1500 Hz, covering bass through upper-mid frequencies for direct integration with a compression driver or tweeter in a two-way or multi-way system.
This design is particularly effective in single or multi-driver bass reflex systems used in professional two-way and multi-way PA systems, powered monitors, and compact bass-reflex enclosures, where extended bandwidth, controlled distortion across the full operating range, and versatile system integration are required.

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): - 125 liters tuned to 44 Hz: high output, strong mid-bass, reduced excursion; -3 dB approx. 40 Hz, HP filter 36 Hz - 150 liters tuned to 40 Hz: balanced response, general-purpose (recommended); -3 dB approx. 37 Hz, HP filter 30 Hz - 150 liters tuned to 36 Hz: extended low-frequency, requires HP filter protection; -3 dB approx. 31 Hz, HP filter 24 Hz
