Chief bonehead

or different

wow lee. am surprised. failed to learn from al?? put me in that coral. never ever heard 2000 mega hertz. maybe, just maybe.....al is wrong...... DA,DA,DAAAAAAAAAAA!

I find this bonehead thread very comical. A network is just one piece of the puzzle for the end result.....HOW A SPEAKER PERFORMS. Paul would have a field day with some of the boneheads on this thread.......

Thanks dave. I appreciate it.

Sheltie dave any more updates on maron? Thanks.

This has gotten BORING!! You guys that sell these "networks" need to just list your website and go there. GEESH!

yAaaaaawwwwwwnnnn.....

A great kisser!!

oh i remember that. in my attempt to try to explain the advantages tractrix to the marketing/lit guys, it was oversimplied. in a nutshell the horns are a modified tractrix equation. i modified the equation in order to get different coverage patterns. i am glad that your guys like the epic. it is still one of my favorites. take care

. A hybrid conical tractrix design ??? Who said?

How you been doing Claude?

Not changing my mind. Sorry.

A misnomer for sure. Roy designed the Jubilee (Jube for short) with Paul Klipsch and designed the K-510 tweeter for the MCM stack and 3-way Jube. He says what makes a Jube is the BASS BIN, not a tweeter. But inconsequential nonetheless. Real Jubes have much better bass. You have got half of the story correct. I did help with Pauls design on the lf of the jub. And yes to me the lf makes the sound of jub extraordinary. But by then I had designed the 510 and 402 and quite a few modified tractrix horns. So when paul asked me set up something to demo the lf with I used the 510. That is what paul listened to on a a/b test with a klipschorn. And what made him smile. To me it was......mission accomplished!!!!I did some experiments to get the most of the la scala has bin and a jub scala sounds very good. In reality a la scala bass bin and jub lf have a lot more in common than a khorn lf.

Wow that mwm looks awesome. Is that yours eldon?

Not true. The 510 is used on the grand hf and hfn.

This info is not correct. The woofers are different.

I don't agree. Most of the cinemas going up (dare I say all of the ones I am involved in) do not use a wall and they exhibit excellent imaging and staging. Although the original spec of thx included a wall, it was like most things in cinema to compensate for the current speakers being used. If a horn is designed for half space then it will need a wall. If not then it won't. And since coverage is a strong positive the crossover points are picked while still in the coverage pattern. Lfs that use a single woofer tend to exhibit some increase gain but again that sometimes is not a good thing.

Just trying to help you get the most out of the system as are most of the guys on here. In full disclosure, you and I have emailed each other and Chris was one of my techs during the testing. I see it on paper and in listening tests. It maybe that the environment of where the speakers are being listened to is dominating the sound. In any case have fun with the speakers and enjoy them. I am quite honored to have worked with paul on his last design. Take care.

Wow I have some of you fooled. As paul would say, I am still learning about those pesky waves......I appreciate it though.

In my spare time, which isn't much these days, the nosepiece along with extending panels on top and sides, does in fact lead to improvement. In something as invisible as those stupid acoustic waves are, there is something missing......got to get some free time to find it. Remember my friends this is supposed to be fun......

Actually, the plots that I've seen of AkabaK and Hornresp plotted with actual measured SPL/frequency on these type of horns show that Hornresp does a lot better at lower frequencies (below 2 kHz) and AkabaK does better above that point (assuming that you can model it in Hornresp). Having two horn mouths emitting side by side at greater than 1/4 wavelength separation induce polar cloverleaf patterns and other diffraction artifacts (including interference maxima)--that are much worse than combining mouths together again internally. I think that the same issue appears when combining two line array speakers together as a common acoustic source (assuming symmetric paths). For instance, Danley claims that their designs achieve wave summation (not cancellation) at the boundary between the horn mouths. Chris Is that why phase plugs don't work?

Smiling comes a lot easier after a brew or 6......

Evanescent and cut-on freq? Cool terms. Maybe too cool for me.....

So how did you come to that conclusion? Specific scenario: stock Jub LF versus Jub LF with a straight walled noise piece at any angle....I'll posit that they're going to have the same polars (same enough to consider the problem unsolved). We know the what limits the bottom end cut off. What limits the hf on folded horn if the diffraction slot/discontinuity wasn't there?

Why am I not surprised doc....
