hey Robert!
great to see you got the "LeKleachorns" up!
and even better that you already like them;
they'll get better as you dial them in.
i was hoping you'd like them, that it wasn't just me...
Davecan,
some people have tried ob bass, e.g.
http://www.diyaudio.com/forums/multi-way/147101-dipole-bass-oris-horn-2.html
sound wise, i find it a real step down from the klipschhorns though...
slower bass, doesn't 'keep up", not as "alive" sounding.
and it doesn't (can't) "pressurize the room" like a front loaded horn can.
just makes the bass sound wimpy to me...
yes i tried it, just because it's so simple, and one way to break in drivers,
obs "work" the driver a lot more, missing the load on front and back.
For a step up in sound quality,
i really like straight front horns w/ 15's for mid-bass.
that's what i'm using now under similar 160Hz LeCleach horns,
(but w/ 10" Tannoy Reds in them), and a pair of Tapped horns for bass,
and a super tweeter coming in @ 10K.
Listening to Mahler's 1st last night,
I've only heard percussion, especially timpani's so real sounding before on one other system. And not get congested, homogenized in complex passages, with huge dynamic swings...
But of course none of that belongs in this thread, or even this forum;
Full-Range sound (frequency response, and dynamics), comes from multiple drivers...
Hope to hear your system again soon Robert!
Some time after RMAF?

Maybe this will sound silly...
Not really, the best horns are merely waveguides which is a folded up baffle with modest gain through better off axis control and why they need to be as large as an OB (before folding) for a given cut-off.

That's only because you haven't experienced OB done right to mate up to horns. 😉 It takes a really large baffle with really low Fs, Qts drivers and as you shrink the baffle, the number of drivers must increase to compensate, so in the scheme of things it's not worth the expense in a typical HIFI/HT app, but where rooms are large and the cost is just part of doing business...........

Hi guys,
Mssr. Serenechaos, yes I love them. Every day I hear more to like. The dynamics are astonishing. I will definitely see you at RMAF, and I hope yo ucan here /critique this setup after the show. I would love to hear your Tannoys!
GM, yowie, that is a big baffle. So those drivers need to be -low- Qts? Not high Qts? It definitely makes the bass horn options look compact by comparison 🙂

It's all about PRaT: pace, rhythm and timing. A horn adds acoustic loading, lowering the driver's effective Qts, or if a pure WG, it at least maintains whatever it is and since whatever it's mating to needs to match to preserve PRaT, the OB driver must have the same or correspondingly lower Qts.

Why is this beautiful actively xover'ed 2way big guy here in the fullrange forum?
(just because a Fostex in it?)
On pictures, Azura horns look shallower than a tractrix (Oris), and its dimensions tell the same thing. I bet it'd be better in the HF portion.
My speakers were brought up, thanks for attention. TBH, my Oris 150 was bought many years ago when I was single and had more money to spare (and also by some impulse with not enough study... 😱 ). Now I won't spend that kind of money on it. It's not to say it's a bad device, just not for me. I keep it anyway, and do my best to make it sound good.
About the bass, horn and OB are the top two in my mind. Odd but true, they work in very different ways and sound differently, but I like them MUCH more than other types of loadings.
I've heard VERY good k-horn. It's not slow at all, but lightning fast, with HUGE dynamics, just blew me away. With corner loading, I guess it's very much room dependent (or the ones I heard were under a perfect tuning...).
I don't have enough space (and corners) for good (large enough) bass horns, so I made it OB. I find it probably a good thing that OB works the drivers harder, given the drivers are 'lazy' in nature. My Eminence Sigma Pro18 is lazy when working in low volume (at home). I think I mentioned that before. With too less excursion, I'd imagine the motions of VC are not entirely transfered to the cone. Some portion might be submerged into the deforming of the materials. Of course I can not measure such thing. It's all in my imagination.
With higher excursions, these pro18's sound obviously livelier. With 6mm Xmax and 4 of them, I don't feel any lacking in SPL or extension in my place (about 50 sq. meter). In fact I always feel nervous or even guilty when playing them loud. (it's a condo🙁 not a good thing to pound the walls and floor... ) What a forbidden pleasure.
Estimated by naked eyes, it's already VERY loud when hitting 4~5mm p-p or so. I've never bottomed them out. Most of the time they barely move. So I'm OK with the smallish baffles. Bigger will probably be better but not really necessary for me.
I used these woofers in vented (and then AP) cabs before. Even louder, yes; deeper, not really. Much lazier, definitely. With even less excursion and 'heavier' loading, their big sloppy cones were very unhappy.
So, these pro woofers are in thier best on OB in my application. Low Q issue is largely solved by amps with high output impedance.
Bass horns work in totally different way with very high pressure and very low excursion. With that tiny motion (and then the sound is 'amplified' by horns), it needs to be very precise at the very beginning, followed by all those complex contruction and resonance problems to take care of - which are far beyond my DIY capability.
So I guess I'd stick with OB, unless money rain falls on me and gets me larger place...

Hi guys,
GM, that is fascinating. I have never heard that before. I would be psyched to try 4 low Fs, low Qts woofers per side. But as you say, at a certain point, a bass horn starts to make sense in terms of cost and size.
CLS, thank you very much! Your horns are really stunning. I saw your full system on the Multi-Way forum and it looks incredible.
These FLH's are really amazing. I thought "dynamics == loud" but what's striking about these horns is that they sort of "whisper" at you with very quiet sounds that get lost on my other speakers. I think I am listening at a lower volume these days, because the Azura's put out so much (detailed, clean, eerily realistic) sound that I don't seem to feel the need to crank them as loud.

Yes, i wuz thinking in context of small room/hifi apps--
the big old theater systems weren't what i was thinking of at all...
even after recently playing w/ 555s--
didn't even think of that type implementation...
context can make such a difference.
would like to hear one of those systems set up w/ digital delay to make up for the path length difference...
Don't need corners for straight horns...Why is this beautiful actively xover'ed 2way big guy here in the fullrange forum?(just because a Fostex in it?)
I don't have enough space (and corners) for good (large enough) bass horns...
And time alignment is a lot easier (makes a big difference to me anyway), Min
Just lots of room lengthwise...
Mine are ~5' long, & they're "small," but great down to 50 - 60 Hz, makes for a very easy hand-off to tapped horns-- super easy crossover, they roll off acoustically...
and really Mr Bond, isn't it time to move up, out of the "fullrange" forum?
😀

No doubt!
I laugh to myself every time I read about the great "downward dynamics" someone writes about concerning little direct radiators...
Mahler (with the great dynamic contrasts, single instrument to huge crescendos), still blows me away...
I can't wait to get compression drivers in the middle three channels...

That's because you're on the wrong forum........... 😉
Or four horn loaded low Fs, Qts woofers......... 😀
Actually, at least initially, folks tend to listen to horns at a higher average SPL since we normally govern it by distortion level which is lower. This in turn raises the 'inner' detail up out of the noise floor and combined with increased low distortion dynamic headroom and improved transient response the reproduction takes on a more life-like presentation.
It never got old having folks over to listen to whatever horns I had functioning and letting them set the volume since their sheer size tended to make them believe I would blast them into the next county. So they'd keep easing up the volume until it was way louder than I usually listened at and eventually would turn to say something and realize they couldn't hear themselves over the din...............

Understood, was just trying to make a point.
Ooh........ lucky you!
Actually, the offset between the 'mid' horn and OB is close enough that there's no noticeable delay, but it's the thousands of degrees difference between it and that little super tweeter horn that had everybody involved in cinema sound reproduction scrambling for a solution. That, and the 'head in a vice' polar response of such a long horn.
Things got better with the 'W' folded bass bins combined with the large multi-cells, but it wasn't until JBL (the man) wised up during his time at Altec and chopped off most of the back off of a half size 35 Hz FLH and filled the hole with dual 15" that proper acoustical alignment with a simple 2nd order XO was achieved in a relatively compact design, depth-wise.
GM
Robert,
You're holding out on me....
I wish I had seen this prior to LSAF, I would have followed you around like a little puppy wearing you out for the details.....
Are you still "over the moon" with this set-up? I've been secretly working on a front horn design for a couple of months. I have considered tooling up a L'Cleach front horn for my Fostex's too, and putting it on top of a " University Classic " Bass horn ( Mid bass anyway ). with a tapped sub set-up.
This may tip the balance....
Jealous John

I'm psyched you like the system. It sounds good but with some caveats.
The LeCleach fronthorn is unimpeachable. But everything else could use improvement. For example, the bass bins obviously require corner placement, so I'm in the process of switching them out for LaScala bins, so I can pull them closer together.
Also, I'm switching out the active EQ for first-order passive. But even then, the bass bins (and to an extent, the AER's) still require a healthy dose of digital EQ to get a flat, extended response (using a computer as the source). Still, it's worth the trouble and good to have EQ as an option.
So thumbs up on the front horn, but I'm also trying to design a BLH to get back to simplicity. It's hard to find that balance of simplicity and performance. Also, it's hard to -really- get a flat response without a measurement kit (obviously).
Your system plans sound pretty killer to me! Especially tapped horns. Are you using Horn Resp?

It's nice to see some front loaded designs, and glad you have discovered some good sound with your design!.
I like the H-Frames a great deal but not much over 70-80hz, so that's why I was wondering about what the 206's went down too etc..
Could be a cool experiment to add in some OB sound below 300hz or so and see how well it mates to the loaded 206 just for fun at some point..
Did the 206 drivers mount easily to those horns or did you do lots of custom work?
Good job 🙂
Hello Dave!
I also own a pair of Azurahorn 160s that I traded Martin a pair of TAD 2001 drivers to get. Whether or not rjbond3rd's 206 drivers mounted easily to the Azurahorns or not would depend on who he got them from. If they get them from, Martin it would be a simple matter of talking with Martin ---{like I did}--- and explaining to Martin which drivers I wanted to use with the horns.
For example I own FE208ES-R drivers which have the same 8 hole mounting pattern as the FE208 Sigma does and Martin made it so all the 8 in, 8 hole Fostex drivers will mount right up to my Azurahorns. Martin could have just as easily made it so the Azurahorns would mount right up to the 4 hole pattern of the FE206E drivers as well. I suppose ---{although one would have to check with Martin to be sure}--- Martin could make a 4 to 8 hole or 8 to 4 hole adapter if it was really needed.
I honestly don't know what I'm going to do with my Azurahorns, because I've finally have gotten my Sachiko/FE208ES-R/Pioneer HW-7 or Sachiko Reference I as I call them to the point where I honestly get goosebumps and sit in amazement with what I'm hearing. I'm almost afraid of messing something up so the Azurahorns will probably just sit for awhile. Although I have thought about what it would sound like to mount the Azurahorns on the front of the Sachikos...
Good listening to you...

I'd not switch out the K-horns for LaScalas... IF you happen to have a room where the k-horn bass gets proper extension that is... LaScala is a major compromise by comparison, imo.
Imo more width is a good thing, unless you like a somewhat compressed soundstage...
If you want time alignment of the drivers then you have to look elsewhere anyhow... fyi, and fwiw.
Just my opinions...
_-_-bear
Hi bear,
I am in perfect agreement with your advice! Alas, the room is a shoebox and the Khorns can only go on the long side, and the seating is not ideal. So I'm doing the LaScala "ported mod" where you cut open the interior "doghouse" and then seal up the top chamber (where the squawker and tweeter used to be), then adding two ports.
I agree that nothing sounds quite as good as a horn. But my room is not great. The Khorns will go live down the hall 🙂

I'm with Bear on this one. The K's go way deeper than the LaScala's will ( over an octave ). ( oops, you posted while I was composing this in response to Bear's comment....Oh well...)
Since I have experience fabbing Fiberglass racer bodies, I'm thinking a L'Cleach horn for my FE206E's too. Still having that old internal debate on how low to design them for. Today I'm leaning to about 200 Hz to save space. Tomorrow I'll probably be back to the 140Hz size, as the bass bin is already over 3' wide. The University Classic bass horn was designed to work from 50-375Hz. The bit I saw on the Klipsch forum said the F3 was down around 44-45Hz with the K-33 driver. I plan to use a lowish Fs ( 26Hz IIRC ) Pro-sound offering from MCM to get started, with plan to switch to a better driver later.
I like the low order filters too, but not afraid to use higher if warranted. I'll have to cobble a measurement system if I ever want to stand a chance of getting it right. What I've been working on was a total 4 way set-up, my design thesis included the desire to get as much bandwidth from the mid horn as possible. I was hoping to get 300-6K out of a hybrid conical with the Peavy Quadratic throat, and a multi-flare conical ala Keele, Danley Et al. but it was requiring me to design a 6" compression mid driver with basically a prosound paper cone driver at it's heart. Possibly way more than I can chew?
The more I think about your system, and the favorable comments about the "Oris, Azura, etc." front horns, AND the fact I already have the Fostex's.....The more I think maybe I should not try to re-invent the wheel.
The Tapped subs are using a Horn Resp design. I worked it up last year for the cheap Dayton 8" classic woofer, that reaches into the '20's free space, and has a relatively small footprint so I can put several in room. I've since picked up a JBL sub driver at a sale, I'll probably whip something out for it since I already have it.
Let us know how the La Scala experiment comes out. Didn't Berndt Doppenburg experiment with a La Scala too?
Are you using the Fostex, or an AER driver in your front horns? your last post confused me as to that...
Speaking of BLH's, I hope to have progress to report soon on the Dallas II's.

Hi Mightym!
I switched out the FE206E for the AER's. Very different sound. However, while the AER is brighter and crisper, I probably should have just tried rolling off the 206 and then using a horn tweeter. It probably would have been overall better in the upper octaves. But the AER with the stiffer cone has a certain crispness which is nice. Worth the extra money? I got them used so maybe 🙂
The only big defect in my system is that it's not all that horn-loaded, really. I'm depending on the Azura's clever trick of horn-loading just so much as to flatten the 8" (pretty much) so the upper octaves are just firing out of the horn (getting some attenuation). As Mssr. Serenechaos says, a horn is just "mechanical EQ".
The ported LaScala has been really popular and so I thought I'd give it a spin. In the old days, all I cared about was tone, but now, I really want dynamite imaging (in a very imperfect room). So I'm compromising in order to get the imaging, and while it will still go down into the 30's, obviously it's far, far less horn-loading than the K-horn type of bin. But at least it's still huge, ha ha.
Dang, your plans sound phenomenal and rather epic! And (unlike my random horsing around, your plans sound well-informed!) With the 200Hz size, perhaps you could do the full rollback? I wonder if Serenechaos will chime in (he's building a 5-way). He got a measurement system from Parts Express.
I am -super- psyched to hear about your Dallas progress as well!

I'm depending on the Azura's clever trick of horn-loading just so much as to flatten the 8" (pretty much) so the upper octaves are just firing out of the horn (getting some attenuation). As Mssr. Serenechaos says, a horn is just "mechanical EQ".
The ported LaScala has been really popular and so I thought I'd give it a spin. In the old days, all I cared about was tone, but now, I really want dynamite imaging (in a very imperfect room). So I'm compromising in order to get the imaging, and while it will still go down into the 30's, obviously it's far, far less horn-loading than the K-horn type of bin. But at least it's still huge, ha ha.
Dang, your plans sound phenomenal and rather epic! And (unlike my random horsing around, your plans sound well-informed!) With the 200Hz size, perhaps you could do the full rollback? I wonder if Serenechaos will chime in (he's building a 5-way). He got a measurement system from Parts Express.
I am -super- psyched to hear about your Dallas progress as well!
