Many of your statements here and there are not valid to begin with, yet you are making a big fuss over them. Who said hard to drive (i.e., lower-impedance) speakers sound more musical? Where did you get that idea?
Covered i the blog post.
Sometimes Hard to Drive Speakers are a Gimmick
Hello friends!!
After about 10 years of looking at speaker impedance curves and sometimes doing an in depth analysis I've come to the strong inference that sometimes speakers are made hard to drive deliberately.
I wrote about it more fully here.
TL;DR : Don't be seduced by hard to drive speakers. They aren't more musical.

@erik_squires, I looked at your analysis of the Focal speaker in your blog post. What happens to the frequency response when those impedance-lowering crossover components are removed? Duke |
@audiokinesis - That's an excellent question. Sadly the simulation and impedance and original hardware is all gone. I should have done a better job of maintaining the data than I did, but I'll explain. The mods I suggested were in two stages. The first cap could be removed with a significant improvement to the impedance with little to no change in the FR. Further impedance benefits would occur IF the first coils in the LP filter were rethought and the 195uF cap was moved. As I recall, you would need a rather large first coil compared to what was original, but it wasn't an extravagant cost item. I wrote about this in detail here but sadly when I merged my blogs I lost a lot of images. |
