Below are some images of what I was thinking (my apologies for the long load time) :Please feel free to laugh!jd*Above : View into rear chamber (45Hz horn /AK151)Above : Same but further awayAbove : View showing the attachment of one of the segmentsA...

[quote user="jessie.dazzle"] There may be better drivers out there, but with my level of experience, I doubt my abilities to recognize them. So though it may resemble laziness on my part (remember, this is the same person that will be constructing a ...
|
[quote user="jessie.dazzle"] If I get you correctly, the graph should display a range of around 12dB from top to bottom, in .5dB steps... Yes? [/quote]Yes, it would do, you might go for high or lower resolution, and there are no rules in it. You shel...
|
[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...
|
[quote user="jessie.dazzle"]However, I must say, I have a lot of trouble accepting the idea of redundant drivers. [/quote]
Yes, it dose not sound attractive to me but it is not the redundant drivers but one main driver and another at minus 9dB drive...
|
[quote user="jessie.dazzle"] Below a certain frequency the advantages become a handicap. At that point (if you were using its EQ capabilities), the SMS -1 would start to step in... Whether you reach that point with your 10" arrays depends on how low ...
|
[quote user="jessie.dazzle"] Are you suggesting : 1) Running the upper bass horn from a second ML2 ? 2) Running the lower bass enclosures (sealed boxes) from a second ML2 ? 3) Running both the upper bass horn and lower bass enclosures (sealed boxes) ...

[quote user="jessie.dazzle"]The thraot size will be 7 inches. [/quote]
Wow, THAT IS BOLD!!!! The 45Hz how from 7” throat – that is very-very cool and very positively-obnoxious.
[quote user="jessie.dazzle"] Yes I have thought about paying someone e...

[quote user="jessie.dazzle"] So it sounds like you're considering a move... [/quote]
Yep, I am contemplating this now…
[quote user="jessie.dazzle"] Criteria :1) Main room minimum 80m2 with correct length-to-width ratio 2) No mid-room obstru...

Jessie, I pulled posts from Macondo Axioms thread and encapsulated them onto a new thread dedicated explicitly to your project. I hope you do not mind.
[quote user="jessie.dazzle"] This would impose a design that is not round but octagonal. It would...

[quote user="jessie.dazzle"] Regarding cone movement versus rear chamber pressure : I understand that low excursion explains to a great extent, the advantages of horn-loaded designs, I just don't understand how something that "does not move", can gen...

The following link will take you to images showing my construction method for small to medium-sized horns (click on the images... to view the explanations) : http://s172.photobucket.com/albums/w3/jessie-dazzle/400Hz%20Tractrix%20Horn/ Since these are...

[quote user="Dominik"]You probably decline this option, because this horn is from plasctic ( You can take carbon horn also).Polish autotech make Iwata 300 for me. You Can order from them what You want.[/quote]
Yes, the Iwata horns are good as ...

[quote user="jessie.dazzle"] Is the S3 as sensitive as the S2? [/quote]
Yes, they are appearing to be the same sensitively.
[quote user="jessie.dazzle"]I keep telling myself that I am almost done making horns, but I keep having ideas to try...
|
[quote user="jessie.dazzle"] Though the frames have wheels and roll very easily, my room is cursed with an elevated platform smack in the middle of everything (about 14 inches higher than the main floor), and to move the horns up on to or down off of...
|
[quote user="jessie.dazzle"] After observing a pair of AK151s operating in free air, though only lightly driven, I just don't see how they can possibly generate so much pressure, as the cone barely moves! [/quote]
Why shout they move? One of the ide...

[quote user="jessie.dazzle"] There are a few good shops in Paris that have shelves and drawers full of components. And, across the channel …. [/quote]Yes, you might experiment with transformers. Sowers have good reputation but I never used them...
|
[quote user="jessie.dazzle"] What really surprised me was how good everything sounded with no filter on the upper-bass horns, and all drivers connected to the same (8 Ohm) tap; sure I'm getting too much mid-range from the upper-bass horn, but its...
|
[quote user="jessie.dazzle"] Yes yes yes .... Lamm Industries is a BUSINESS... This is abundantly clear whenever I order tubes from them! [/quote]
Hm, I did not know that you use any Lamm electronics. In fact I just realized that I have absolu...
|
[quote user="jessie.dazzle"] In my case, it has nothing to do with convenience, and believe it or not, everything to do with quality.[/quote]
Hm, I would question it. Are you saying that you are able to play from your PC music that you got by rippin...

[quote user="jessie.dazzle"] What I question: A rectangular mid-range horn... Why? [/quote]In consistency with Occam's razor principle I think that they went for rectangular mid-range horn become they layout of the speaker called upon it. I di...

[quote user="jessie.dazzle"] Make sure the power switch is off, and connect the power cord.[/quote] Unless you are a republican. If you are then you need to change voltage with power switch on and power cord attached.

[quote user="jessie.dazzle"]While not present to the point of ruining the experience, I would love to reduce the background hiss coming from the MF and HF horns/drivers. [/quote] ML2 should be absolutely silent. Pretty much it you drive with ML2 a 11...

[quote user="jessie.dazzle"] I have 2 ULF "boxes"; each has an 18" McCauley 6174.
The enclosures are sealed and each measures 14 cubic feet. They are made from 70mm thick concrete blocks.
Power is from a pair of M1.1 amps (100 Watts each)....
|
[quote user="jessie.dazzle"] So last night I angled the upper horns of right channel down toward listening point, and left the left channel with horns firing along parallel axes. [/quote] Jessie, do not forget that if you made the dramatic-enough ang...
|
[quote user="jessie.dazzle"] For now, the amplifiers I use are a pair of Lamm M1.1s (was going to look for a pair of used ML2s, but more and more considering building a pair of Meliquaides). Using the M1.1s with a pair of V.A. Parsifal/Encore (direct...

[quote user="jessie.dazzle"] Its still not perfect, and I had the mic 1m from the membrane of the driver (had not yet read Romy's last post where he recommends putting the mic back at listening point). [/quote]
I would like to stress it again that t...

[quote user="jessie.dazzle"]Upper Bass : Frequency range between 100 and 500Hz – Driver loaded into a 120Hz straight horn, driven by DSET dedicated channel. Mid Bass : Frequency range between 40 and 100Hz – Driver loaded into a 45Hz straight hor...
|
[quote user="jessie.dazzle"] Also, I'm convinced that a too-big space is horrible for audio as well as being non-conducive to good mental concentration (some of the best ideas are born on the toilet!) [/quote]
The subject of playback in very...

Sorry, I do not share your sentiments with those 3 reasons. Below are my reasons.
[quote user="jessie.dazzle"] Three reasons:
1) To try high passing your upper-MF channel (S2 > 400Hz horn) above the 1250Hz secondary resonance assiciated ...
