JBL B380 with 2235h transducer...

[Dr.db]

Hey,


I got a 2235h woofer and I`m wondering how to tune my box.

I did build an enclosure of 130litres, same as the B380. But I don`t know anything about the tuning of the B380.... How many ports, which diameter and length ?

Would help me heaps!!

Hi Olaf,

the best choice is going for www.linearteam.dk (http://www.linearteam.dk). Here you get the winisd software for free. It's a small and simple calculating program for loudspeaker enclosures. You can try different things as enclosure volume and port diameter. Have a try.....

... best tuning for 2235 will be around 30 Hz.....:):)http://www.audioheritage.org/vbulletin/images/icons/icon7.png

A B380 is tuned to 26hz with a bump filter and a 20hz high pass in the BX-63/63A box. Do a search to find more info.
