Adding a resistor in a parallel wiring system

Hi Al,

Thanks for the response. Now I'm thinking, since the zero has several input wires, maybe I could use the 3X wire on the three 8 ohm drive and then connect the 4 ohm drive by itself on the 2x wire. That way all of them will practically be 8 ohm. Would that work or will that just burn the amp? Thanks.

Thanks,
Ryan.

I see, I wonder whether it can be wired backwards. I'll test them tomorrow when I get them thanks

I see. Thanks. I think the increased damping factor as a result of the zeros could help. I'll add the resistor to see how it goes thanks!

Hi Al,

Thanks for all your inputs and help. The zeros are installed yesterday and they are great. To take care of the 8 ohm vs 4 ohm problem, I think I've found the ultimate solution. The 3 ohm resistor would reduce 50 watts of power (directly only to this speaker) to reduce to about 16 watts, which is not what I want. If all the other 8 ohm drives receives 25 watts, I want this 4 ohm to receive 25 watts also. Therefore, I will install a 1.5 ohm resistor which increases the power transfer to about 25-27.5 watt given the error tolerance of 5% on the resistor, which is reasonably close.

The new damping factor for this drive will be 2.5 and with the zero's 4x setting, this damping factor should go up to 10 or so, which is again, reasonably acceptable.

Is my analysis correct?

Thanks,
Ryan

Hi Al,

Sounds great. I really appreciate all the help this time (and last time too!). Now I feel much more comfortable ordering a pair of the 1.5 ohm resistors.

Thanks again,
Ryan Huang.
