Hi. Newbie poster here so be gentle.
My new project is converting an old (1940s?) wooden radio into a mono, three way, 24v, bluetooth capable speaker for camping etc. but i have run into a modelling issue that I cannot find a previous example of. The bass is being handled by a ported dvc visaton W 130 X driver which will be powered by two separate channels of a 4 channel dsp amp. (zoudio AIO4CH)
My main issue is how to model this in winisd for the port? values are given for the driver according to how the voice coils are wired but there is nothing suggested for this situation where each voice coil has a separate amp channel powering it. my apologies if i have missed this question elsewhere.
Thanks for any advice including why this whole project is misconceived.
NB. no antique radios were harmed in the making of this speaker. It's a 1980s reproduction which didn't work.

If you do it right, one amp on each voice coil is not different from one amp driving both voice coils in parallel apart from the impedance that's presented to the amp.
Thanks for the reassurance DcibeL. The question of how to enter this driver into winisd remains however unless I'm missing something basic which is quite likely. Many of the TS parameters are given with three choices depending on whether you are wiring for one voice coil, two in series or two in parallel. I am not really doing any of these exactly.

Thanks again. I wish I'd asked here earlier. I spent an age trying to find this info elsewhere. where should i have looked?
With post #2 in mind, I Googled 'stereo using a dvc wiring diagram' out of curiosity and there it was 😉, otherwise no joy trying numerous variations.
