Congrats! Somehow I can relate. Nice work all around on those. Enjoy!

Very nice looking assembly.
I can totally 'picture' work like this, framed, on a wall behind each speaker, with a art/display lamp highlighting them.
Has anyone assembling this type of ptp circuit on wood, considered using insulated eyelets? It probably makes little or no difference at audio frequencies, and low circuit impedances, but it still makes me wince... a teeny tiny bit.
Great looking. One can only imagine the time and effort put into those crossovers.

Interesting. The schematic you posted shows a 4 leg circuit, but it appears your CC systems only have 3 legs and yet there are 3 trim-pots.
How are you running your bi-Amp design - wondering how you are doing the hi-low split and what amps are involved?
Thanks for the time and the detailed information!

Always fun learning more.......
Restoring the legend, one cabinet at a time
Is there any HF attenuation on the woofer? active or passive?

Changing to Legacy Audio and started with a Silver Screen HD for my center between the 250TIs
Not at this point. We will be experimenting with a passive LF bandpass filter to see what difference that makes. Any suggestions?

Simply Incredible!!!!! - Now I wish I did the same when I built my DIY 4345
Hi there, i am new, I am Andrea from Venice, Italy, i am planning to restore a couple of 4341, and obviously even to rebuild crossovers... i have seen your beautiful job, but i have a question , i have seen many times the option for to bi-amp the crossover, but never seen if for low section is employed the marked part (lines mark) for bass section in giskard project or what kind of low pass filter, someone can help me?
thanks in advance
Andrea
Hello--Welcome to the LH forums. I'll try to answer your question, though I have no direct experience with that speaker. As poster mbotts indicated in post No. 25 above, when building a new crossover for biamping, the components within the dashed lines on the schematic sre omitted. This deletion replicates the effect of moving the built-in biamp external/internal crossover switch (if you have one) to the biamp position. The low pass and high pass for the woofer/midbass handoff are then handled by an external line-level electronic crossover, which you must provide, placed between the preamp and TWO power amps in each stereo channel, one for the woofer and one for the upper three drivers. The type of filter and whether 12, 18, or 24 dB slope would depend on what you have available to you and/or what sounds best to you. The external crossover should be set at about 300 Hz, although, if your crossover has the felixibilty, you might experiment with frequencies a little lower, down to about 250.

I never thought of displaying a crossover. I have to admit it looks great like this so nice work!
I have always used this stuff for larger audiences in bigger venues so I am amazed at what people put in their houses. I am jealous!
