Yeah, you’re right. From your completely uninformed and ignorant reading of a simple graph, you obviously have nailed it. You can now build your own Pulsar on the cheap. Oh, but then there’s this:
From Jeff Joseph as of today:
“The filters we use are asymmetrical, there is a very steep slope on the woofer and a gentler slope on the tweeter. This infinite slope topology differs from conventional filters in several ways. The implementation is not as steep as our earliest designs, because I found this to be the best sounding trade off of filter q and driver integration.
Compared to slow slope filters, ours confines most of the overlap between the drivers to below the crossover point, where wavelengths are longer. This prevents the lobing effects of wave interference. The speakers balance through crossover remains intact along a broad vertical axis.
The other major benefit is that we can derive the full benefits of using metal cone woofers because the special filter effectively suppresses the high frequency ringing the stiff cones exhibit. A second order filter wouldn’t come close to doing that. ( the metal woofers are typically +13 dB at the hf breakup frequency relative to their usable output, and a 2nd order filter only rolls off at 12dB per octave)”
@kenjit — does that answer your question?
How you gonna replicate this without violating a patent? Best of luck with that buddy! Just go home and lick your ill-informed and ignorant wounds. You have absolutely no idea what you’re talking about and no basis for your claims, and if you try to come back at this in any misinformed way, I will have Jeff come back and smack down any other uninformed and misguided crap u try to lay down. Live in ur own silly world dude.
