These are 4-way Open Baffle loudspeaker design with 3-way main panel and inverted W-Frame subwoofers.
Objectives:
- Low midrange distortions, by assigning separate drivers for low-mid and high-mid duties
- Low vibrations due to W-Frame subwoofer's opposing forces
- Small footprint and height
Challenges
- The 5" high-mid drivers may proven to be too small for the baffle width
- Designing 4-way crossover will be more complex due to phase interference
- Back to back dome tweeters' known limitation. "dipolar" response, instead of dipole
Drivers
Tweeters: Vifa DQ25 with phase shield removed. Back to back.
