Question

Isobaric configuration problem

Isobaric calculations don't appear to be working right now, my understanding is that the low frequency efficiency should improve with two drivers working together, however the results for one or two drivers in the same box are always identical.

I'll add the examples in a comment, as previously they broke the software somehow.

Thanks for your appeal. There are no calculations bugs. The mistake in the label when you choose "Isobaric". It must be about the number of pairs not about the total count :)

Oh right, so entering 1 would two speakers and entering 2 would be four speakers? Perhaps you could change the label to "Speaker pairs" to clarify this.

Yes, entering 1 means 2 speakers. I'll change the label from count to pairs.

I've changed the label from number to pairs. Thanks for you comment.
