Question for crossover

[zag55]

Buongiorno, un consiglio tecnico. Quale filtro fareste nella configurazione d'Appolito (perché il cabinet è già fatto) in bass reflex, con questi tre diffusori. 2 woofer Seas CA 18 RNX, 1 tweeter VIFA XT25 TG. Tubo reflex Monacor MBR 75.

The two woofers will inevitably cancel each other out long before the Vifa can take over, e.g:


I would do some nearfield distortion measurements of the Vifa, figure out how low it can comfortably play, then cross it over as low as possible.

Also, please use English on ASR

Is your tweeter the XT25TG30-04? If so, that can easily play down to 2000Hz with a third order high-pass filter.

For the woofers I would recommend a 2.5 way config, meaning the top woofer plays until the tweeter crossover, the bottom woofer is rolled off early. This provides a larger vertical sweet spot at the cost of some sensitivity.
