Have you swapped boards with the other cabinet to verify the problem follows the crossover?

That should have been the first test. If you have two of something - insert the working one in place of the non-working one.SethRocksYou wrote: ↑Wed Jun 03, 2020 3:10 pm Have you swapped boards with the other cabinet to verify the problem follows the crossover?
Or a faulty/incorrect connection somewhere other than the crossover circuit. Poor crimp somewhere perhaps.Bruce Weldy wrote: ↑Wed Jun 03, 2020 5:09 pm If it doesn't work, then put the other board in the "working" cab. If it works, you know it's the driver.
Yeah, I'm not a fan of the crimp connectors. I'll use them only on the lead to the driver and only if it has a really good connection. Everything else get twisted and soldered.SethRocksYou wrote: ↑Wed Jun 03, 2020 5:27 pmOr a faulty/incorrect connection somewhere other than the crossover circuit.

I love the non-insulated crimp connectors and use them wherever I can, with or without added solder. However, I share your opinion on the insulated connectors and think it's reasonable to suspect an issue there and worth looking into. It's not super common, but it happens.Bruce Weldy wrote: ↑Wed Jun 03, 2020 5:51 pmYeah, I'm not a fan of the crimp connectors.

Throughout this whole thread, I've wondered whether there is a good connection there every time I see those. It's easy to get the wire too far in the connector and you end up crimping down on the insulation instead of the copper.....also use the crimper on your wirestripper instead of needle nose pliers.
I was talking about crimping down on the insulation of the wire inside the connector. I like the crimping tool.SethRocksYou wrote: ↑Wed Jun 03, 2020 5:57 pm

Understood, and I completely agreeBruce Weldy wrote: ↑Wed Jun 03, 2020 6:10 pmI was talking about crimping down on the insulation of the wire inside the connector. I like the crimping tool.SethRocksYou wrote: ↑Wed Jun 03, 2020 5:57 pm

Yes I got bass and woofer is moving along nice sound loud too. It works Yeehaaa! I hook it on the mid pin. Planning on redoing all 3 way thingy terminal waiting for UPS.Grant Bunter wrote: ↑Wed Jun 03, 2020 2:47 pm It just seems highly unusual that two faulty components ended up on 1 board.
I want you to try 2 things.
Disconnect the mid board from the 3 way thingy, and hook the woofer board to that lug, see if that works.
Undo the screw on the + "in" side of the woofer board and show a nice, close, in focus, pic of this end of the inductor.
I agree with Bruce, twist all together then solder and heatshrink.Bruce Weldy wrote: ↑Wed Jun 03, 2020 9:06 pm Just twist all three wires together, solder 'em and slip some heat shrink over 'em. Nobody will ever see 'em again.
