@charles1dad Hi Charles, you are correct and we don’t see much discussion either. The truth is, I really don’t believe most designers have delve deeply into series crossover networks.... I’ve done a fair amount of work and have come up with Truth’s of the differences. So, why use one or the other? Normally a designer uses series or parallel because they are more familiar with one over the other, but in reality depending on the drivers used, a series or parallel could be better than the other. So why? In theory there really is no difference, say using a speaker that has perfectly benign load, say a ribbon could get there, but in reality: Resistance and inductance...... Think of an impedance compensation circuit in a crossover....In a parallel crossover, we series a combination of cap, resistor and/or coil to flatten out a speakers impedance bump. Now on the crossover itself in a low pass on a woofer depending on first, second or third order, we would already add a combination of these parts in series. In parallel vs series, the part would be somewhat reversed. So, in one case or the other, the crossover part would work differently toward the natural inductance and resistance of the woofer itself. So depending on the woofers natural resistance and inductance, the odds are that with one or the other design, we could cut down on the parts by needing less compensation or a better impedance or phase with this driver vs the other type crossover. In my experience, its the drivers own impedance, inductance and capacitance that dictate which type crossover to use, just as frequency response dictates which order we would use. So one would not necessarily sound better than the other, but could depending on the drivers in a speaker in their entirety. I hope this is written in a way that makes sense for all, Tim |
Hello Tim, thanks for taking the time to address my inquiry with such a clearly written explanation. I have been told by some that with a series crossover the drivers are more directly connected to each other in terms of their contributing influence or sonic character. In contrast when using a parallel crossover it is easier to separate / isolate the innate characteristics of each driver. Or in other words less of an interacting relationship between the drivers. I don’t know if that is a practical reality or just theoretical. Charles |
First This is not precise but close on what your experience from your system Room = 40% Speakers 40% Equipment 20% Second if you have heard the klipsch Heritage speakers which are properly setup for the room they are in with its center sound stage and music dynamics and you are still looking for what you want. then Klipsch may not be for you. I have a pair of 42 year old Klipsch La Scala’s that I bough out of a garage. These speakers were beaten up badly as they probably were bar room speakers of dance hall speakers. Basically they looked like crap. I brought them home hooked up my system: Audrivana on a win 10 PC 16/44 Flack files Minidsp SHD - XLR out to a Crown XLI 1500 and RCA out to a 20 year old Velodyne Crown to la Scala’s And YES Klipsch Heritage speakers needs a sub There was a Wow moment, even my wife noticed it, as well as everyone else that hears them, for me they will be my last set of speakers Everyone is different, every room is different, when it is right you will know it, Good Luck and enjoy the music Dire Straits, You and Your Friend is a great way to test the Klipsch Line for sound stage and dynamics https://www.youtube.com/watch?v=MQF669AZVvw&ab_channel=SoundSommelier Good Luck and enjoy the music |
