the dB/octave specification of the crossover?

I have a dumb question the dB/octave specification of the crossover. A speaker designer wrote on his Facebook that dB/octave is like the resolution of a television. For example, for the same set of drivers, if we apply a crossover with 12dB/octave, the sound won’t be as detailed as with a 50dB/octave crossover.

Bullshit. :)  Utter and complete nonsense.

The crossover slopes are chosen to be complementary to the other drivers as well as to minimize interference from one driver to another as you go off axis.

It does not improve your resolution in the way it is stated. There are some benefits to high slope crossovers, but even Joseph Audio, the most well known proponent of high slope crossovers seems to have decided they are not that useful.*


Best,

* I'm going from recent measurements of his speakers, which seem to use more conventional crossover designs.

Whoever that designer was, don't buy a speaker from them!

Thank you everyone for the valuable input!

On his facebook, he builds speakers with TAD, JBL, Altec drivers. His crossovers looks very massive and impressive. I have been following his page until he made this statement which puzzled me a lot because there exist some hi-end speakers with only 12dB/octave.

I'm not an electrician either so I will check out Danny Richie video clips about crossover. 

@twoleftears :  I won't :)

There are many who are proponents of 1st order, time coincident crossovers as well. Vandersteen and Thiel among them.

If you are curious, build some. :) How about the Seas A26 kit?  Has 1 capacitor and one resistor for a single order (6dB/octave) slope on the tweeter only. Can easily be converted to 2nd order (12db/octave) as an experiment.

@erik_squires  I have been thinking of building speakers with full-range Audio Nirvana drivers (which doesn't require any crossover) for my parents. 

The Sea A26 kit looks to be more room friendly and really nice. I will check it out. 
Thank you.
