Comparable 15.0" Drivers
Drivers with similar piston area, resonance and Qts — useful alternatives when the Peerless STW-350F188PR01-04 15" High Power 264-1652 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 (87.1 L at 20.6 Hz) would need a 56.5 cm port; the recommendation is retuned to 87.1 L at 23.7 Hz so the port can be built.
