Ok I know this might be a stupid question but I have to ask to be sure that what I am doing is ok , I have a jbl3110 that I want to use with a jbl3106 , I would like to use the 3110 HP to feed the input of the 3106 so that I can hook up my 2440 horn to LP and 2405 tweeter HP , however I will not be hooking up a LF woofer to the 3110 crossover , that will be unused . Will this give unwanted results , will the crossover work within its design parameters or will the sound and crossover be compromised . I was told before that it would not matter , but I just wanted to know from others being that I just rebuilt these crossovers .
No you can't is the fast/easy answer. A simulation from the result of cascading two filters give a different result of what you would expect from the individual xos. But if you are into experimenting/diy why don't you connect them and measure; finfing level and final crossover frequencies and attenuations. Have in mind also that the "experiment" might have resonanses/impedance of the drivers and all their specs like the crossover freqs for the tweeter and horn under control. Post to make sure. Individual xover freq are 800 (3110) and 8000 (3106).

Thanks for your reply , would it be the same result if I were to use a dummy load in place of the woofer , or is the characteristics of variable impedance produced by woofer needed ??????? This just a though

No. The woofer is the only one out of the equation. It doesn't go throgh the cascading. This is my understanting now, trying to read your mind here.
Now what would happend to the mid and tweeter from adding a second order xo with 9uF in the HP (JBL 3110) to the JBL 3106 configuration and resultant. The best way of doing it is testing all the passive components involved in SPICE. Or designing a new adequate crossover.

Hi again purejaqzz,
Why (if u r not using a proper 3-way), aren't you go and bi-amp using both xos to start with. (!?) that's another good option if the horn is adequate for the 800Hz xo, did you think about that.

I am using more than one amp , the only problem here is that even with the second amp powering the 3110 , I do not have a second woofer to put to LP , my only move is to hook up the 2440 to the 3110 , but with no woofer to install on LP I was trying to find an out with the 3110 and some other fix other than other LP speakers. Again I do thank you for your input.
Let's see if I understand why my post was not reasonable?!
-> One amp, one crossover 800Hz, woofer + horn.
-> Second amp, crossover #2 @8KHz, tweeter only.
-> One amp, one crossover 800Hz, woofer + horn.
-> Second amp, crossover #2 @8KHz, tweeter only.
I really thank you for all you efforts in trying to help me sort this out , what you have mentioned I have done , but I thought that using any of these XO that you had to have both outputs hooked up . I think that's what I took your first reply to say , in the very last post you said to hook up the horn and woofer respectively and then on another amp connect tweeter to Xo only . In that case there is still the matter of one output being used , is the second not going to pose an issue ????????
From my small experience with JBL (others work with it everyday) from what I remember you can cascade the 2 filter crossovers with the 2 frequencies 800Hz and 8000Hz, they are pretty separated from each other in frequency. I'm not simulating in SPICE that's why I was reserved before.
You can test with attenuator set at -10dB as for 4671 System.

Woofer?
Attenuation has to do with system you are using if you look at the pdf at various diagrams of the LF drivers.
Disregard my previous post with the 2 networks and amps.

As to your question , I have a set of le15a JBL woofer . I use those with my lx5 XO and a le85 horn . the thing is I would like to have the other horn and tweeter play from the other 3110, 3106 crossover . only thing is that with that is I do not have other woofer to put to that 3110 XO . hopefully this helps you understand what I am trying to do .
The compression driver connected with JBL 2395 Lens should be the JBL 2441 (2") compression driver and not JBL 2420 (1") or JBL 2425 (1"), in relation to the previous posted by me (#12).
JBL 2441 CD http://www.jblpro.com/pub/obsolete/2441.pdf
I don't know any other details at this time, if that's the original CD's they are using and if they had any repairs over time (1973), substitute type diaphragms, etc.🙂

I apologize for being late on this scene.
A friend of mine just came at me with a similar set of questions.
1) Bi-amping and/or tri-amping with good electronic xovers is a far better solution because of the variety of conflicting impedance curves from the drivers and passive xovers.
2) That said, my friend wants to try passive all the way with one stereo amp (he is currently bi-amping). He is focused on the difference between the 3110 and 3110A. He is using a 3106 on the top already. Etc, etc ... He is "restoring" a pair of 4502s but with 2235s instead of the LE15As.
If there is any interest in Spice modelling / sims, I would like to pitch in. lesorr at gmail. Thanks.
