Spawn Olson/Nagaoka Horns the Next Generation

[chrisb]

Thats for sure, and no to cats or kids, just shame that the wife doesn't like them

no matter how long you've been together that's always hard to predict, and unwise to ignore: there are more things we can't be changed that will pi$$ them off, "unacceptable" audio gear is an easy sacrifice

I completely agree, thats why I have insisted on a study being built when we have some renovation work carried out, it helped pointing out the advantages of not having all this 'mess' in the main part of the house

Score one for me

Smart man!

and noted that the enclosure for the FE206En was twice the size of the one for the FE126En

That's news to me.

 

[fringy75]

That's news to me.

Hi Scott.

Looking at the width, the fe206 is twice the width of the fe126 version unless I have missed something?

 

[Scottmoose]

Kirishima is 11.75in wide, internal. Kongo is 5.125in wide, internal. 11.75 / 2 = 5.875, not 5.125.

Note that the cabinets also have different depths, and thus slightly different flare profiles & volumes, as well as different compression ratios &c.

That was my third mistake thanks Scott, it makes the fact that they work so well even more of a fluke.

Mostly it just shows that Olson's original BLH concepts load the driver well enough to alter its specs somewhat. IOW design a horn with the desired in-room response and within reason a wide range of drivers will work acceptably well.

His original 15" 'full-range' corner horn studio monitor's response with loading to 30 Hz when recordings could only get down to a rolled off ~50-60 Hz:

Hi Greg,

That graph is pretty impressive for any era! I wish my speakers measured as well.

In case anyone's wondering, I'm not "that" Olson, I'm the other one.


Best Regards,

then there's Lynn - oh a guy could get confused


well actually, Terry, having met two of the remaining members of the Olson audio aristocracy, not so much confused as amused



see you in August

Hi Greg,

Greets!

Absolutely! Pretty amazing for just a single 15" driver. All it would need today is a super tweeter and an appropriate high output impedance amp to drive it.

I'm crawling through net for more info ...... I read that Bill Woods sort of promised to make plans and either sell them or share for free (both options OK with me ) ;

is there anything new about that ?

GM

Yep, he was a bit good wasn't he? So much for 'progress.'

 

[GM]

I read that Bill Woods.....

Greets!

Dunno, I only vaguely recall him either piecing an original back together or building one from data he has and that was many years ago now. Why not just ask him?

GM

 

[Zen Mod]

I did , few years ago ........

obviously , I'll do again

 

[talaerts]

Dear all,

Question:

Where (if anywhere) are the simulated low frequency responses of these enclosures?

 

[faithintruth]

I'm in the middle of building Dallas II's but would also love to see spec's on that horn!! Did I read it had a Karlson slot?

 

[Scottmoose]

Dear all,

Apologies, only just noticed this. They'll be on their FH page when it's done, but don't hold your breath -FH3 has been around for the best part of, what, 2 years now & we still haven't had chance to update the site. Time = something neither Dave nor myself have much of at present.

Dear Scott,

I am about to begin building the Haruna design using Fostex FE 166EN. Would like to seek your recommendation on the path of the internal speaker wire. Would it be appropriate to drill a hole in the bottom panel of the driver chamber and seal any gaps with silicone... or .. is it more appropriate to follow the path through the folds?

Do you have any recommendations for the base? Spikes or Granite Slab?

 

[planet10]

I'd run it thru the throat and out the back on the first fold.

A lot fewer holes to seal up and can be swapped if needed at a later date.

You will need to have a removable binding post assembly.
