Zilch's AK Design Collaborative - Econowave Speaker

Well, it's about time you started using the 18sound XT1086. :)
It's certainly not as if I'm running out of options. :tongue:

The frequency response looks beautiful.
Where did you source the XT1086s from?
US Speaker is the distributor, I believe. They're not $10, but they ARE aluminum.

It's rare I achieve +/- 1 dB here, for sure.

[I ain't messin' more with that.... ;) ]

US Speaker lists the XT120, which is ABS, but not the 1086.

Loudspeakers Plus has the XT1086, for about double the price of the XT120. It looks like the 120 only holds directivity down to 2k, so it wouldn't be a good sub for the 1086.
 
one Altec Santana 879a cab e-wave project complete, and reproducing music....i cannot believe myself...pix when the pair is done. jbl l14a woofer variant.
 
Zilch , which one of the Econowave deluxe version sounds the best to you? Deluxe with the 3012LF or Deluxe with 3012HO or Deluxe with Deltalite 2512? and which one give you a better bass response?
 
The Mighty Zilch does not trouble with lesser efforts. All of his examples sound the best and better.:D

Note for those unfamiliar with the use of smilies, this is intended as homage to Zilch's immense contributions to the EWave revolution, not as sarcasm.

3012lf, but that doesn't mean I've done the best possible design effort with any of them. I'm seeing what's up with higher-efficiency woofers, mostly.

Someone called it the "Horn" revolution recently. ;)

Interestingly, it's forum-specific; there's nary a mention on some major ones, and plenty of naysayers when first introduced to any group.... :)

WooHoo! the 1086 horn solution is in :thmbsp:

Question: Would you alter the LF section (or HF for that matter) of the x-over if one were to be using a 15" JBL 2226 or E145?

I happen to have the 1086's and a pair of B&C DE25's (anyway).

Thanks, RC

True. I'm actually surprised that the Tech-Talk crew hasn't picked up on it yet. That would likely change if the DC300/220TI/Trap makes it to an
"official" PE project.

The crossover must be optimized for any specific combination of components to achieve the best performance.

As you saw on LHF recently, measurements are key to getting it "right," and in my view, expressed many times here, having that capability is essential for doing this stuff.

I've shown in the TechTalk forum that it can be done successfully with a $150 HOLMImpulse setup; WankLab should be stepping up its facilities soon. :thmbsp:

It's gonna take for a couple of them to get hands on with waveguides, and some are nibbling at that with dome tweeters. Every forum has a dominant paradigm with principals vested in supporting it, and there's substantial inertia. It's gotta come from within, ultimately, with advocates accepted as part of the group, for any substantive shift to be perceived as an advance rather than a loss.

Of 33,000+ threads over there, "Flex Your Mettle" just moved up to #6 most viewed. Perhaps somebody is paying attention; interest in EconoWave has brought major traffic to the site.... :yes:

Interestingly also is the May "Stereophile". Reviews of two horn based commercial efforts...the JBL 1400 and Klipsch P17b...:music:

I did see that at a matter of fact. Them is rough characters indeed ;) When funds allow, that might just happen. Until then...

Maybe the "Optional" can say adios and I can go from there. I guess a generic tweakable version is only discussed when it's the original ewave. With that, it appears to be a LF free-for-all. :scratch2:

Indeed, and we've always included tweaking the LF as coming with the territory. Those with bigger flashlights get a better view, is all.

We're all learning, and it's clear there's no jealousy on my part with respect to what little I know; it's all posted right here.

[There's no dearth of haters out there, tho.... ;) ]

Well, like they say, you cant please everybody. If you spend too much time trying to make everybody happy, you may very well end up miserable in the process.

JBL 2226 and B&C DE250 is the premium version of Wayne Parham's 4pi speaker. I bet you can find some good info on the LF section (and HF, of course) there.

Edit - I see that WP also has the 4pi crossovers for sale....that might save you some time

Yup, I'm pretty familiar with Wayne's work. In fact I just finished a 4Pi implementation for a JBL 2425 and a horn that shall remain unmentioned on these hallowed ewave pages ;)

My desire now is to come up with something so I can try out with the XT1086 and B&C DE25. I do realize that Zilch's work is proprietary to the two drivers and horn but I guys gotta start somewhere for horsing around. It's just wire nuts and some time if you happen to have what you need.

2226h in all-JBL setup

I just swapped out my Eminence Magnum 15HO for 2226h in my 2 ways (Ewave PT guide, but JBL 2426h comp driver and diff crossover, posted earlier in thread). Attached is the 2226h crossover derived. Big improvement with this better shaping. Haven't measured or refined yet, though.
