[quote user="oxric"] In my mind, and given my specific circumstances, the question of strategy is inextricably tied to the resources in terms of time, efforts and funds that I will be able to devote to this attempt to achieve what I have in mind ...

Hey Romy I read your requirements of a mid bass horn. I am using jabo tratrix KH-55A(320hz) with altec 288 and I want the mid bass to go under that. I would use a trattix round midbass if it was possible. But it's just not with in my abilitys to buil...

I would worry that there could be an interaction between your electrical filters and the filter formed by the horns themselves.I, too, like to trust my ears and I would ten to trust yours more than mine but nonetheless you have created quite a compli...

Now I have been listening the different crossovers trying to shape the new Macondo general balance. This is so fascinating ceremony that I do have a lot of fan. The things doing alone very well. I boosted upper bass and it worked now very-very well....

Romy,
More to come soon but a couple comments regarding bass horns ( and one on Tractrix horns ) :
The Edgar Seismic subwoofer ( 18" JBL E155-4 hyperbolic-exponential folded horn, 40 Hz Fc ) works very well in my room - much better than the 1...

I will be dubiuos about the slanted enclosure if not done properly, all drivers must be time aligned and since they are playing the same frequency, deficiencies in time alignment become more obvious. I made a slanted enclosure but with the drivers ...

Room is extra nice, better then most i have seen on the web. We all will hear from you telling us there is no bass, in your new room. It looks like 300Hz down will suffer because square footage increase like 10 fold from last room. You will have much...

Khorn has about 2meters path length so they have to be positioned closer with false corners in Romy's case to be aligned. If they are at the back one has to add the distance from horns plus the path length of the khorn bass bin and delay the rest of ...

Congratulations first for your success with your bass horns, Romy, but have you given away the best position for the lowest channel? Is the wall to the attic where in fact two large IB woofers like the Fostex FW800 or the 24" Hartley-Luth should sit?...
|
|
Is speakers like altec 19 have time aligned drivers? I think I have never seen in internet time aligned 3-4 way horn speakers with oken/jensn as a bass.Slowly I am closer to finish my first speakers with horns, the frame is adjustable (35-45cm drive...

"and romy is out because he didn´t find a similar construction he will have heard?"no he is in, he know nothing,he can´t look the IMP, not the SPL,not the range, etc.and will know how it sounds he is not able to read and translate the feedbacks on my...

because floor josts support and extend the walls (they are solid 2"x6")so just screwed the board tightly to them. Because I needed the boards only within 10' so I have 3 rows of 5' +5' with the seam in the middle. I cut the second layer of bards so ...

In MiniMe, after study all recommendations and talking with a number of port speaker manufactures I decided to go a simplest route. It will be one single port at the bottom. What pervaded me was the Precision Port Company. Then make 2” port with 4” a...

[quote user="Bill"] If you are going to build such a huge cabinet or put a hole in the floor to use the basement as a chamber, why not just build horns in the basement with a straight 8-10 foot section in the basement with the back chamber re...

Well, a lot of horns are put into box enclosures of course. This is really a complicated subject. The baffle must be dealt with in a manner similarly for all loudspeakers so designed of course. More interestingly is the potential fo...

Romy,If making a Tractrix Horn to cover between 100Hz & 1000Hz do you have to choose an Fc or mouth size that equates to 50 Hz? I've often read, and don't know if its true, that tractrix horns actually need to have their Fc an octave lower t...

One more thing I would like to add: what if despite of the oversized throat problems we have a task (as you, NL, proposed) to use the overthroat horns (overthroat - horn with oversized throat size, let it be one more Romynizm). I think the dealing wi...

I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.As you have noted time and again (with which I agree almost completely, after reading a lot of 'research' [many claiming to defy the laws of physics...

Another bogus idea.If a perfect upper bass could be achieved by means of spherical (approx. 1m diameter horn), what would be the next acceptable solution,if space considerations do not allow big horns? Perhaps that could be a line array of small dire...

[quote user="jessie.dazzle"] Romy's comments on "axial rotation" of the horns (meaning in this case, angling the horns) has me thinking. I had planned to build in a vertical tilt adjustment for horns located near the floor and ceiling... I woul...

Romy,
It's good to have all this info in one post.
Regarding N° 5 :
"5) Horns shell have a sufficient mass properly projected to a given channel’s LF boundary and the horn’s mass should be properly distributed within a horn."
I have seen a lo...

[quote user="jessie.dazzle"] This event really reinforces my curiosity to try such drivers in the Mid-Bass horns. As there are plenty here in Europe, that is exactly my plan (most however are not 16O... don't know to what extent that might be an issu...

[quote user="jessie.dazzle"]In this case, below 50Hz, I think el`Ol is right to suggest that you consider using DSP as a permanent solution. The SMS 1 is in theory the silver bullet... You just need to find out if you can live with it long-term. Be...

If it is dedicated music room then it is great but offset a lot idea that I have in my mind for integrated room. I have made a number of comments why I do not like the idea of “dedicated music rooms”, which does not make me to blind to recognize the...

I think using the Ale woofers would be pretty awsome, do you have the space to fit in 2 separate 2.5 meter long horns?http://twogoodears.blogspot.mx/2013/06/digital-skyrocketing.htmlDo a search in Stephano´s wonderful site, there is a nice descrpti...

I would write to Cessaro. prices for the big systems vary according to the type and number of bass horns, to give you an idea the Liszts we have here , have a suggested retail price of Euros 120k, Gammas would be at least twice that again depending ...
|

And as one of the other perpetrators...The nature of this kind of thing is compromise. The owner of the bass horn system wanted to run them together, for the enlarged horn mouth, and so we did - there was never going to be enough time to play about ...

I'm wrapping up my horn building activities and have some leftover items available. 1) Edgarhorn 80Hz Mid-bass horns - Pick-up in Seattle - $350Condition - 8/10 based solely on age. No visible imperfections. They are in the identical condition as...

Oh, btw, I've built some bass horns for Ming Su....see link.A lot of my projects use CNC'd layers of MDF or ply.http://www.audiovoice-acoustics.com/forum/showthread.php?t=932...
