WR125 + G2si crossover

bjackson · 23rd October 2005, 10:56 PM

Does anyone have a completed crossover for these that I could borrow for a design of mine? I know RAW uses it in his designs but I assume those are proprietary and not open source. If this is not so, I'd be happy to have a look at them.

Not only is the crossover proprietary but it is not for the G2Si but for an OEM model, the RA104.5.

Well on his website he indicates:
RA104.5 ribbon (Aurum Cantus)

and the cost is 100 dollars, which is very much inline with a G2si.

As Bob said our ribbon is made by Aurum Cantus but is NOT the G2Si
Ours has a different motor as well as face plate.Our face plate I had made at 104.5mm for those who had previous tweeter hole cut out at 104.5mm this will fit with a small cut in the inside of the opening for the motor.
Almost a drop in replacment for driver holes cut to 104.5mm.
Nothing even close to the same between the G2Si and the RA104.5.
Yes a great price in line with other ribbons

And yes 6th order at 3500.
Why 6th
well stepper the slop the better dispersion off a ribbon and driver!
AS well a more controled inductance and resistance and impedance with a step order nextwork.
This is achieved by more parts but smaller valvues.

Say in a 2nd order network you have to use a 1.8-2.2mh on a 6th order you use 2-3 inductors ranging from .1mh-.7mh
