Another WinISD question
When doing multiple drivers, I noticed that it tends to put them into parallel all the time. Sometimes you want them wired in series, or maybe even series/parallel. How do you force it to have the correct overall impedance?
@tvor-ceasar I have never really messed with that setting in WinISD. I mainly use it just for box size where impedance doesn't affect it. However, I know when you input a driver, there is a setting for parallel or series. It is normally on parallel. I wonder if you change that to series if it would affect it.
From what I can gather, that only affects something like a DVC where you can either connect it in series or parallel. I can't find a setting anywhere else that deals with that. Only reason I ask is because that would affect SPL and cone excursion, not to mention the impedance curve.
@tvor-ceasar - I cannot find how to change the greyed out portion, but under the Driver tab with the number of drivers, they have a voice coil connection part.
Now, what you could do, even though it has parallel and series when entering the information about the driver, even though 1 voice coil so DVC doesn't apply, change it to series there, then save it (like with the name of the driver, then series beside it so you know which one to select). Then, when you change the number of drivers to 2, it might stay in series and appropriately adjust how the speakers are connected. Just a thought.
I tried changing the switch for voice coil, but it will not save it as series when not a DVC.
@ajc9988 thanks for the suggestion.
I tried that with one I had already put in, via the driver editor, before using it in a design, but it wouldn't keep the series designation. I'll try a new driver and see what happens, but it will be later if tomorrow, I have to work.
I'll also check with the WinISD team to see what they have to say.
You're right that it'll affect impedance and sensitivity, but it shouldn't affect cone excursion. If you know how much power your going to give it, the program doesn't care about the impedance. Basically when you put in 500 watts, the program doesn't care if that's 2 ohm, 4 ohm or 8 ohm. It's just going to show you if the driver can handle 500w or not. You'll have to decide how to wire the impedance for the power requirements you decide is best for the driver.
