Notes
Build notes
Sample data: values are illustrative, not measured.
A 2-way top pairing a 12“ B&C 12NDL76 woofer with a B&C DE250 1“ compression driver on a 90°×60° waveguide (e.g. 18 Sound XT1086). Demonstrates a mixed driver table: cone woofer and compression driver in one enclosure.
Crossover
- Recommended crossover ≥ 1500 Hz to stay above the DE250’s usable lower limit
- The CD mates any 1“ exit horn; coverage is set by the chosen waveguide
Usage
Flown or pole-mounted on a sub. High-pass at 80 Hz.
