Hello,
I have got an never used JBL 2213H in original box and best condition.
I want to built a subwoofer for souuround (other speakers are evm 10m + jbl 2425 + 2344A).
I have an aktive subwoofer amp modul.
A look in JBL 4312 technical manual network shows
- 1.5 mH in line to + Speaker and
- 0.01 uF parallel to 24 uF + 3.9 Ohm between + and - of speaker.
I do not understand this.
If you calculate the speaker a big cabinet of 200 Liter is needed, but 4312 Monitor is a 42 Liter cabinet???
What do I have to do to built a 42 Liter Sub with aktive subamp? Is there any passive network requested?
Yours
