Hi, i just rebuilt a pair of JBL j900mv tower speakers on a budget and i want to set up a better crossover design than they came with.
The towers are built as follows:
8” chinese silver flute woofer
6.5” dayton audio fiberglass cone midrange speaker
~1.5” titanium tweeter that came with it
I was thinking of using the Dayton Audio XO3W-375/3K 3-Way Speaker Crossover 375/3,000 Hz as a prebuilt board which is way better than the 3.5khz crossover already installed from the factory. The speakers are also being paired with a polk PSW10 so the deep bass is already taken care of.
As a separate thought, i was thinking of using an inline high pass such as the Parts Express 100 Hz High Pass 8 Ohm Crossover
• this whole setup means the sub would play from 0-100hz, the 8” 100-375, the 6.5” 375-3,000, and the tweeter 3,000-20,000

Have you seen that the filter responses of the pre-built board will offer better integration when working with your devices?
Hi
I have a bunch of coils on ebay if you want to build your own crossover. . I am retiring from speaker and audio construction and repairs. I used different suppliers over the years and tuned coils and trimmed capacitor sets for cross-overs for decades. Parts Express usually had several different manufacturers' coils available- just depended on how much you wanted to pay... I also used DigiKey, Mouser, and Tayda for parts over the years.
I used The Loudspeaker Cookbook for many years to guide design. Vance Dikason is a good guy. However, sound is so personal, that the best thing is to build and listen and rebuild until it sounds right to your ears.

What I'm saying is that I couldn't say the same as you're saying here, because I don't know which one is better.
i see, well the original drivers have been stripped out of it so the only original part is the 3.5kHz crossover that was integrated into the enclosure. i’m sure the Dayton board would help a little more than the stock one but i just wanted opinions on if that was a viable option
You might be right.. nothing is certain without further testing but I agree the change of drivers may (or may not) invalidate the old crossover.
However the acoustic nature of the speaker remains. The old crossover may still be better. The replacement crossover is unlikely to take the cabinet into consideration (baffle step). In any case you're going to have to modify it to set the level of your tweeter.

I see what you mean now, I just don’t have the knowledge on how to make my own crossover or how to determine the values for the inductors and capacitors it would require. I also do not have any speaker test my equipment and my ear would be unreliable in noticing minute differences in sound.
