Comparable 8.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Bomber SUBWOOFER 8″ B-ONE 200 WRMS 4 OHMS does not fit your target box volume or tuning. Each entry links to its full enclosure design and Thiele/Small parameters.
⚠️ Engineering Notice for Builders
- The textbook alignment (11.2 L at 37.4 Hz) would need a 64.6 cm port; the recommendation is retuned to 14.0 L at 22.4 Hz so the port can be built.
- Port length (80.2 cm) exceeds a straight internal run; use an elbow bend, slotted vent or 3D folded duct to fit the enclosure.

Frequently Asked Questions
What is the recommended ported (bass reflex) box volume for Bomber SUBWOOFER 8″ B-ONE 200 WRMS 4 OHMS?
Load Forge's calculated alignment puts Bomber SUBWOOFER 8″ B-ONE 200 WRMS 4 OHMS in a 14.0 liter vented enclosure tuned to 22.4 Hz, reaching an F3 cutoff of approximately 51.7 Hz.
Can Bomber SUBWOOFER 8″ B-ONE 200 WRMS 4 OHMS be used in a sealed box?
Yes. In a sealed (acoustic suspension) enclosure of 14.1 liters with a Qtc of 1.301 (above Butterworth: Qtc cannot fall below Qts (0.92)), the system exhibits an F3 of 51.9 Hz.
What port dimensions should be used for Bomber SUBWOOFER 8″ B-ONE 200 WRMS 4 OHMS to avoid port chuffing?
Sized from cone displacement (Sd × Xmax), a minimum port diameter of 5.0 cm with a length of 80.2 cm is suggested; check the port air velocity at your drive level in the Load Forge Studio.
