Thanks for taking the time to respond. I highly appreciate it.
I referred to a pdf by crown audio on how to build a speakon cable which I found on google. Not sure how to attach the same here but steps specified in it were
Crown Field Support Engineering
Issue Date: 17 December 2013
Ref. No: Speakon Wiring for Bridge #0001
Subject: Making a Bridged Speakon Cable
1. With your NL4 connector open you will see 4 internal connections. These are referred to
as ‘Poles” and you have to look close but each are labeled 1+, 1-, 2+ and 2-. The picture
below we tried to highlight those connections and labeled for easy identification.
2. Connect the two speaker wires to 1+ and 2+. The 1+ connection or pole is your positive
to the speaker. The 2+ connection or pole will be the negative to your speaker. See
3. Now you can close up your connector and you want to label this end of the cable that it’s
wired for bridge mono as the other end of the cable, if using speakon there, is wired 1+
and 1-. It’s only at the amp end where the speakon would be wired 1+ and 2+
If I have to ammend the cable per your suggestion, do I also need to switch the wiring "inside" the sub? (From neutrik to driver?)
What about the humming noise? How do I get rid of that?
I do have the high pass filter set at 30hz at the crown end, which is the lowest it will go. Do I still need a minidsp?
I did not doubt the diy way and that's the reason why I chose it but the results tell otherwise. I has planned to upgrade my speaker to 1299's and add another DEV to my system but I am holding on on all till I figure this one out. I am seeking all your help on the same. Thank you for your valuable suggestions and guidance. Please lead me to bassland ... Cheers!
