René - Acculution.com's latest activity

I have actually shelved an article that goes in to this, as the designs I made were based on very recognizable loudspeakers, and the...

Given that it was a nearfield measurement (what distance exactly?), besides being lower in level the second aspect of the tweeter now...

Have you looked at @j_j 's presentation (download the PPT) on Acoustic and Psychoacoustic Issues in Room Correction. As far as how, one...

While Pauls video is too hand-wavy and mixes up phase and time, I also don't think Amir's video has the proper nuance, as the...

@Keith_W, I think you still mix up a few things. Loudspeaker drivers and fullrange single-driver loudspeaker systems are generally...

The problem, which Renee explains in the page linked above, is the intuitive notion of a phase shift as sliding the entire waveform...

Yep. For successful DRC it's best to make the speaker behave like a true minimum-phase system first (no allpass "excess" phase), then...

You might want to try a pure phase correction of the crossover allpass behavior first, that is, unwrapping only the phase rotation from...

What a nice thesis.

Yes, for a two-way system, I guess perfect would mean (s+w0)/(s+w0) transfer function, and clearly he will not have that. I am just...

Sure, but the claim is his, not mine ;-)

For completeness, can you also extract the step response for this axis? Not that it looked bad at all actually for the initial axis, but...

I am not native English nor American and certainly not a lawyer. But watching his video I was really wondering if the word Arbitration...

Seeing a set of measurements with feet in place measured on the woofer axis to see how things change would be informative. I...
