Wouldn't it just be shallower? Can't get much narrower or shorter.I will assume there is some language barrier here and/or I didn't explain above clearly enough.
So I'll try to explain my thought process a little better.
I should have also stated that I was looking for comments about why this would or wouldn't work. To expand my understanding.
Yes, I generally understand the region and purpose for cardioid in these speakers.
This (cardioid) is achieved passive (via the side slots)?
If so, the rear LF drivers are only there for only for LF, it's not to achieve cardioid response (in the 100-500hz range).
But my understanding on some speakers that are actively achieving cardioid via using the rear drive as cancelation in this range.
If my understanding of a)how these achieve cardioid is correct and b) looking at the near field driver the MF and HF can cover from 80~100hz and up.
Then these speakers could be made without the LF drivers. And the LF area could be covered by subs.
This would reduce the size and cost of the speakers. And move the LF to subs which are likely less expensive than the LF portion of this speaker and have better flexibility for placement in room.
The Gradient 1.4 is another passive cardioid design, as is the midrange unit of the Gradient Helsinki 1.5.
