SWR input output plug?

[yobtaf]

What happens if you plug into the output on SWR SOB? lets say you accidentally plugged into the output not the input what could happen?
I have an SOB and it sounds like poop now and Im noticing creasing on the speaker so Im wondering if something like that was done at on point.
TIA

Are you talking about the speaker output?

yes it has input and output on back of cab. Im guessing so you can daisy chain

That's not going to be the cause of creased cones on the drivers. That's from too much power at low frequencies. Once they are damaged they need to be either reconed or replaced depending on the driver and the availability of parts.

Yeah recone probably not going to happen. From reading I think the Legend CB158 is the speaker Ill replace this with.
but what about the input output? does that cause any problems?

Those should be wired in parallel, so there is no difference which one you use.

Those jacks are all inputs and outputs, there's literally no wrong way to hook them up, unless you plug into 2 amp heads at the same time.

Correct, and don't do this!

Also, don't plug 2 channels of a stereo or dual power amp into a single cabinet like this for the same reason.

Before you do make sure that they are a suitable candidate for the cabinet. Ohms and Watts are among the least important paramentsers!

from a bunch of reading this and the kappalite non lf was the 2 that came up over and over

But not necessarily for YOUR cabinet. Each driver has what's called Theil/Small parameters that have to be taken into account when loading them into a box. They may be a perfect fit in your case or possibly more likely tear themselves to bits.

ok so all the threads about it came to that, how would you tell me how to find the right speaker for this cab? Im all ears on learning this.

so are you saying that I have a greater chance of this happening than it working for me?

You have no idea unless you (or somebody else) do the math. There are lots of recommendations made on the internet by simply pulling the words out of their butts. Those recommendations may be ok, but they may also be worthless.

ok how do i do the math to figure this?
inside W 21/ D 15.75/height from port to top 15.5/ port depth from front inside 7/ port opening 2

 

[yobtaf]

anyone have answers to the speaker question? the doubt was put in my mind with no way to find truth...

About 2.5 cubic feet internal, port area is 2" x 19" = 38 sq in w/ 7" depth Legend CB-158:


If the above is correct, the vent is too large for the box, and you can't really make it much deeper so if you were to decrease the area by about 30% it would be fine. Otherwise it's pretty under-damped.

The kappalite 3015 is a little better matched to the box as is, wouldn't hurt to decrease the port area by 15-20%

Thank you very much for your help. I really appreciate it. The box has white padding on top and sides, does that make a difference? And to decrease the vent size what would you suggest to do. And if it's not decreased what is the outcome just for more knowledge for me.
Thanks again

Fill in the port about 2" per side

Not doing so makes the box kind of boomy.

The lining doesn't matter for this purpose.
