Hi all
Just aquired a pair of JBL kit speakers which seem to be similar in layout to the L300/4333.
(The enclosure, really well-built)
.. until i took a closer look that is. They utilize the LX13 crossover coupled with 2231A woofer, 2410 midrange, 2312 horn, 2308 lens and 077 tweeter.
(Thought I might as well replace the crappy posts with new ones)
I know that JBL sold kits with the LX13 crossover, and that those kits came with the N8000 add-on in order to use the 077.Problem is, my speakers don't have the N8000. Instead, they have something that looks like a non factory have-a-go crossover for the 077 which consists of 2X 2.2uF caps in series, and that's it!
This is coupled with 2X 22 Ohm resistors for the midrange which actually sit _outside_ the LX13 itself (see pictures), one wired in series with the midrange and one wired across its poles.
The green/yellow and brown wires go to the HF-posts on the LX13, I should add. Furthermore, I've never come across a JBL-kit which has the 2410 horn coupled with the other drivers.
So my questions are:
- Does anybody know if this weird crossover setup for the 077 is a design from JBL? (I've always thought that the N8000 was the way to go when adding a 077 to an LX13)
- What's with the two resistors strapped around the posts of the midrange? Are they supposed to be there? Dosen't the LX13 support the 2410 natively?
- Is this stuff any good? The speakers sound fantastic in every way apart from the bass being a little weak, still very well defined though.
Help would be much appreciated since I've reached a dead end by now and can't find anymore info on the Internet.
Best - Mike
