Simple LCR placement question

spice house · 29th March 2011, 03:03 PM

You have a crossover box with 1 set of inputs and 3 sets of outputs to drivers

There is the same LCR network in parallel to all three drivers at the outputs (three networks)

would this be equivalent to one of the same LCR network across the input set? (one network)

You can assume no other circuity

Trying to understand AC flow at the crossover better thank you

Hard to guess what you're talking about without a diagram, but I would assume no until I see it.

Don't know why the pic won't show

Are those two equivalent? same LCR network obviously

beautiful circuit diagram i know i'm for hire

Ok, no they won't be the same.

There may be a bigger issue to talk about, if you're interested in expanding it. If there were actual crossovers in the diagrams they would be placed between where you have the single LCR and where the separate LCRs are. These two types of circuit are used for different things. The single LCR used directly after the amp would be used to flatten the impedance to make the speaker an easier load for your amp. This would have no real impact on the frequency response of the speaker.

The separate types are used for flattening/altering the impedance of individual drivers so the crossovers, for example, can perform more predictably. Series components need to be placed before them to make them effective.
