hello, I am owner of an enclosure 4320 equipped with the following speakers: LE15A, 375, 2405. the filter was produced by Rinaldo Bassi 25 years ago. I would like to know if the filters 3105 and 3115 would be adapted for my configuration. I don't know if the horn of the 375 is adapted to go to 500 Hz.
Thank you for your advice
Maurice
You don't mention it, but I assume you are using a 2311/2308 horn/lens combination with the 375. If so, you have close to what I am using above 100Hz in 4325 cabinets.
I would highly recommend you look into building the voltage equivalent circuit that Giskard provided of the 4333/L300 if your 375 is 16 ohms and the 2405 is 8 ohms.
The woofer / mid crossover point ends up at about 800 Hz.
It's fairly easy to get the parts and put together. It works very well.
Try a site search under 4333 or 3133 crossover.
