Crossover Resistors.. Advice Needed

[gilbert-]

Hello,

I have the following crossover to build for a MTM TL using the Vifa p17/d25 combo however I am having trouble sourcing the necessary resistors. All parts have been obtained apart from these.

I can obtain resistors that are close to the reccommended values locally - if I use these following values for some of the resistors, what effect would this have on the crossover?

R3 changes from 20.0ohm --> 22.0ohm
R8 changes from 0.30ohm --> 0.27ohm
R13 changes from 25.0ohm --> 27.0 ohm


As you can tell, I am a novice when it comes to crossover designs. All credit goes to Zaph for the crossover design

Thankyou, any help would be very much appreciated.

Phillip

Hi,

R8 is not real, its the DCR of the inductor, same for R1 and R11.

R3 - Add a 220R 1 watt resistor in parallel with 22R to give 20R.
(This is probably not necessary as it won't make much difference)

R13 should be fine as 27R instead of 25R.

Alright, thankyou very much for your reply sreten.

I will do as you suggested.

Thanks again,
