zigmahornet design for Fostex 126E

[same64]

Hi guys.
I like zigmahornet enclosure but no idea how much bigger should i build.
It was build for smaller driver.
But i,ve red somewhere that goes well with 126e.
can someone give me proper dimensions?
Thats my first broject..

thanks in advance.
best regards

It was originally designed for the evergreen Fostex 103 series drivers, and TBH, isn't all that distinguished, other than the fact that the exceptionally thin front baffle does mean imaging is good insofar as a recording allows it to be. You'd need a new design of this type from scratch for the 126, which really does prefer to be in a back-horn, if you wanted to optimise things as far as possible.

hi

thanks for replay..
Well that's my first attempt to do fullrange speakers.
Im trying to learn as much is possible here.
I though i will do something like that first .looks very simple to build.
Then maybe later on try something more advance.

Same64,

Have you heard the FE126 yet? Do you already own a pair?

If you have not heard / own a pair I would recommend you try to listen to them before purchase.

To repeat what Scott said...

If you wanted to put them in a "Zigmahornet like" cabinet then it would be a
new design, the Zigmahornet was designed for the FE103 Sigma, which was discontinued many years ago.

 

[Scottmoose]

It would also, as noted, be a new design for a driver that fundamentally isn't very happy with such loads.

As a 1st project, FE126En in a Zigma-like enclosure would not be that auspicious a start. Even with the proper driver, the Zigma produces less performance than some much less resource intensive speakers, they even produce more bass. With something like FE126En which needs some trickery to lift the low Q bass up to the level of the midrange bass would be woefully shy (ie a horn). You'd likely be better just popping them into a sealed box and add a woofer per side.

Ropies Solo 103 are an example of something better for 103. And jury is still out on whether this box will work with new FE103En.

What amplifier do you have? Choice of driver should be influenced by this.

If you want to have a good 1st experience, and have something relatively simple to build, there are other drivers to consider (with discontinuation of FE127e (which i have some of the last stocks), very soon none of them will be Fostex )

well, FWIW, I heard this pair of Ziggies at the VSAC2008 Show (with Dave Merrill's 4" driver)

(photos courtesy of 6moons)

while they do image very well indeed, to be frank they absolutely need bass assistance, and even then suffered from minor midrange colorations due to very shallow / narrow CSA as well as rather a lot of midbass ripple

The 6V6 amp by Scott of Sterling Audio was a visually gorgeous build and quite possibly responsible for more than a bit of whatever degree of magic the Ziggies delivered

 

[same64]

thanks

Thanks guys.
So what design would you recommend?
Looks like zigmahornet is not a good idea.

 

[same64]

hi

Well to late now .I already bought the drivers.
So would have to go ahead with it.
As for amp i do have 813 tube amp and couple of t-amps .
I was actualy thinking using them with t-amp.

Perhaps a BIB. There were several designs on zillaspeak.com but the site appears to be done at present. Perhaps someone reading this will have the plans for the 126 BIB available to share.

These would be the links you'd want for the Fostex BIB designs

the rumor of Zilla's site's demise is somewhat premature, but I think the relocation was not widely announced

rebookmark the site links posted above and you're good to go


BTW, Scott Lindgren has some designs for previous generation of Fostex drivers. Depending on your personal latitude the new FE126En could be considered a drop-in upgrade for existing enclosures for the FE126E - that certainly appears to be the case with anecdotal reports from Ed Schilling and his peeps

 

[Andrewbee]

...but the site appears to be done at present

That should have been -down- at present but now I know the addy changed so thanks Chrisb.

This is newbie question I know, but I looked at the graphs on the links provided. The speaker response is awful, a mountain range of huge peaks and valleys - how can this be acceptable at all ???

 

[Scottmoose]

Because those are simulated responses and thus don't account for in-room loading. In practice, they're nothing like as bad as indicated (in fact, they're quite good).

have you ever tried to reconcile unsmoothed actual in-room measurements (which could give a roller coaster enthusiast severe motion sickness) to the unfortunately unquantifiable musical enjoyment delivered?

I'm waiting for an iPhone app for the latter


all the measurements in the world or our current "understanding" of how the brain/mind works won't fully explain what happens when the gibberish of data of any of our sensory inputs are interpreted into our perception of reality - or why they differ among individuals

 

[planet10]

As Chris alludes, there are a ton of enclosures for the FE126e, and all indications are that the FE126En is sufficiantly close in specification to be a drop in.
