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 ...

I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

Hi Jeff,I am certain that the best midbass was NEVER in a corner horn. Every fold in the horn is a new resonance. Corner horns need many folds...In addition, if you are very "anal retentive" about phase alignment - how do you integrate a corner horn?...

I pulled a mono set of these exact looking horns out of a movie theater they were installed in 1946 :)the system consisted of 2 of these bass cabs and one gigantic dual compression driver horn on top for the entire theaterI am no horn guy and looking...

Rewind, this is funny because it is not at all terrible. I have thought for some time I would try paper mache "wings" on a WR driver, but I've never gotten around to it. Believe it or not, your little demonstration has rekindled my interest.At some ...

Orchestre de Radio France archival recordings of live concerts all day on the radio. Phenomenal performances with lush, full textured strings, crisp horns, deep bass volume. Isaac stern playing the brahms violin concerto and I am in heaven.Romy can't...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

[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 ...

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 ...

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...

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...

[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...

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...

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 ...

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...

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...

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...

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...

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...

Here's a pic (link) of my listening position.When I built my large Bill Fitzmaurice bass horn...I had thought about placing it in that space above the speakers, firing into the corner. I may still do that...but the sub is serving duties in the separa...

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 ...

[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...
