Notes
Build notes
Sample data: values are illustrative, not measured.
A fully active 3-way top. The LF section is a ported chamber tuned for either the 15DS115 or 15SW115, both have identical Vas and Sd; the SW115 goes slightly lower with its lower Fs while the DS115 gives marginally more output above 80 Hz. The mid chamber is a sealed enclosure for the 6PS38. The HF section mates any 1“ exit driver; DE360 or DE250 both fit.
Driver combinations simulated
Six simulation files cover the per-section and full-system responses for each variant:
| Config | Kick | Mid | CD |
|---|---|---|---|
| A | 15DS115 | 6PS38 | DE360 |
| B | 15SW115 | 6PS38 | DE360 |
| C | 15DS115 | 6PS38 | DE250 |
Per-section sims (lf-15ds, lf-15sw, mid) are useful for evaluating driver substitutions in isolation. Full-system sims assume active crossover at 700 Hz LF/mid and 2000 Hz mid/HF.
Crossover
- LF/mid: 700 Hz LR4 (24 dB/oct)
- Mid/HF: 2000 Hz LR4 (24 dB/oct); respect DE360 minimum at 1800 Hz (DE250: 1500 Hz)
- High-pass LF at 60 Hz to protect kick driver
Wiring
Active tri-amp recommended. Each section is 8 Ω nominal: requires three amp channels.
