Thinking on this, I came to the conclusion that if money was no object the last thing I'd consider would be a Combo! A combo by its very nature is a Buch of compromises in order to fit into the combo format.
That said I do love my Ampeg B15NF!
Your question should be can your PA tops handle a bass without being damaged? Also an active cabinet will not alter the combo's output to 4 ohms. In my mind doing as you suggest will gain you you very little if anything.
I agree that a socket tester should be a vital part of a gigging musicians equipment. Before I left the UK I saw many instances of dangerous practices. One I'll never forget was a 13A plug with about fifty feet of doorbell wire connecting to a VOX AC30. I was terrified for the player!
In my mind the biggie here is to be certain that there is no possibility of a short between the conductors. That would not bode well for the health of a solid state amplifier.
Just remembering my JBL days. A pair of 1x15 cabinets each housing a K145. These were topped off by four TL style cabinets each housing a K120. The rig was incredible and sounded even better. Load in and out was very tiring though!
Twice as many speakers in the 4x10! Simple.
The rotational position of the volume control has no real relavaance to the output the amplifier is producing.
Why would it be? The crossover should have two wires coming from it that connect to the woofers. They should be the same colours as the wiring between the woofers. If this is so in your case connecting these wires to the same colours on a woofer should bring the tweeter back on line.
Not trying to Rain on anyones parade but a 1x15 is really a poor match for a 4x10 no matter how often you see it. You'd be better off stacking the 15 on top of the 4x10. That way you can hear it's cries of pain as it fails to keep up with the 4x10.
Well bill I'll be eighty in January! I still can remember my "horny" times! LOL
I just don't see the need for such to advertise a bass amp. Besides which the amp I use is capable of 2000W. LOL
