please see my invention in my web-site

If the woofers compress the air in the box at the same time, it is a bipole, not a dipole. If they are wired as a dipole would be, your bass is limited by the width of the box.

Hi,

Nothing I can see as an original invention.

You don't need a magnetiser at all, simply wire the drivers properly.

Your last diagram is not isobaric, it is push-pull parallel.

the connections are correct
this method is named reversal
and can compensate the asimmetry of engine

Hi,

Nonsens, even patented, remains nonsens.

As described in the patent the drivers are facing in the same direction (diffusing cones as they are named...whatever this name is good for..but they still remain simple diaphragms)
Reversing the magnetic field in one driver does change only the direction of excursion but does not change any parameter (TSP) of the driver at all. It has the same effect as wiring the driver in opposite polarity. Nothing is gained, especially is there no linearization effect.
Wiring two drivers -one with reversed magnetic field and the other with an unreversed one- and connecting them in antiserial or antiparallel mode, the whole behaves exactly like two identical drivers connected in series or parallel. Both drivers will exhibit the same excursion directions. Therefore its a simple parallel arrangement, or with the drivers facing in opposite directions a Bipole.
It would be interesting anyway to actually see the magnetizer, capable of reversing the field

This is another bad example of misusing the idea of a patent. Its not new, its of no use, its utterly nonsense, its wasted time, money and effort. Its just good for a laugh

I believe this is true.

IIRC Mallory used to do this some decades back, and I think I read about it in Vance Dickason's LDC.

read better v.d. book........this isn't the same situation.

this is no electroacoustic-sense thinking and stee must uderstand this.

to many times stee tried to present this as an invention,but he loose his time.

I didn't buy the part about remagnetising the drivers.

I didn't know this.

Hmmm........

As ever you can patent something completely useless.

a)
The connections are correct for reversed magnetic fields,
but reversing one field provides no benefits whatsoever.

b)
As there is no benefit, there is no real method to name.

c)
Is simply not true. There is no assymetry compensation.

Utterly pointless.......
