OB experiment

Inspiration came from NAO Note II RS and LX521. Both of them are based on active crossovers. I wanted to find out what it takes to make similar construction with passive crossover.

The goal was to use each driver in its dipole region, where FR falls down to low frequencies with -6dB slope. To make this concept feasible, very narrow baffles and 4 bands are required.

This project was never finished. Following plots were modelled with actual measurements and are results of passive crossover.
