New Diy Synergy type horn in natural oak

bwaslo · 07:02 PM

I just wanted to show off the new horns I made for my diy Danley Synergy speakers. Pretty, huh?

Now to convince the wife to let me make some 4ft wide ones

Looks really good! I haven't had a chance to go though the build thread you posted but I'm hoping you'll answer 2 questions I have. Can you explain the function of the bottom "stand" section. I assume this is for LF or sub duty given the slot. Also did you spend a lot of time simulating/modeling and did you prototype at all?

I did notice that you said the Synergy Horn patent was granted. Congratulations to Tom and company. Though I've heard that some inventors are trying to keep the patent pending status for as long as possible, not sure why.

Congratz to you as well, bwaslo, for completing your build.

The bottom part is just a ported box for the woofers (that fire forward out of the elongated ports in the horn). Done mostly for looks and because I hate speaker stands (why waste the volume when the woofers can use it?).

Yeah, there was prototyping before making the black mdf horns, though the first proto actually worked pretty well as it was - that one was just two-way, the later ones were 3-way (a separate proto made for that, too). Lots of modeling with HornResponse.

I think inventors want to keep the "patent pending" in place for a long time because the clock to expiration doesn't start till the patent is granted, for applications already in the system. I believe the law has changed now, there is something called a "provisional patent" instead that you essentially file yourself and that protects the invention until a patent gets granted; but that time comes off the patent expiration clock.
