How many crossovers are there in a biwirable speaker? Is it 2?
Follow Ups:
All the passive filters used (in total) are usually called a "crossover"Most cheap speakers in the world use a one cap high pass filter for the tweeter. Sometimes they use a resistor to lower the tweeter volume too.
My own EPOS speakers use a one-cap no-resistor crossover and still manage to sound good at modest volumes. Some speakers use dozens of parts in their crossovers and sound good too.

But unlike most speakers, your EPOS speakers have custom designed woofers designed to roll of at about the correct point to cross over to your tweeter/crossover. Very few manufacturers do that. And while your speaker does better than most that use this simple crossover at a fairly flat frequency response there are compromises there compared to a properly designed more complex crossover.
For instance, 3-way Magnepans (ie. 3 drivers) have an external passive XO that takes 2 pairs of wires (one for low, one for high) but the "high" input is then further split in an internal XO to ribbon and mid-range.Typically, you'll have as many "crossovers" as there are drivers ... but, again, it depends what you mean by a "crossover"!! :-))
If you define a "crossover" as a pair of LP & HP slopes intersecting, then a 3-way speaker has 3 drivers and 2 crossovers.
However, if you define a "crossover" as either:
* lowpas
* highpass, or
* bandpass... then a 3-way speaker has 3 crossovers.
Regards,
Let's define a crossover as a frequencey filtering unit with a pair of inputs.My speakers have 2 pairs of inputs and 3 drivers. I imagine that one pair of inputs leads to a low pass xover which then feeds the woofers.
The other pair of inputs lead to a high pass xover which then feeds the tweeters. I presume a more complex xover is needed for the mids. Is this right?
Hi amdan,You said: "My speakers have 2 pairs of inputs and 3 drivers".
Are the three drivers all different sizes? IE. do you think you have a woofer, a mid-range and a tweeter?
If so then 1 pr of input posts probably leads to the woofer (with bass lowpass filter), while the other pair leads to the mid-range and tweeter, combined. This "other pair" must therefore feed into a mid bandpass and a tweeter highpass filter. (A bandpass filter is simply a highpass & lowpass combined.)
Regards,
Thanks Andy. BTW my speakers are 3 way.
