[quote user="Romy the Cat"][quote user="guy sergeant"] I think it would be quite difficult for anyone to set up any sort of production of drive units and not become an 'industry' participant. It's quite remarkable that you manage to use a turntable, ...

[quote user="Romy the Cat"]Of cause not but did you read and understand the Macondo
Axioms? The Macondo Axioms proclaims that an individual driver and individual channel
have to be set in maximum suitable for own topology operation. According to Go...

Robert, what I meant is following: when you will be collecting requirements for you own drivers specification and will evaluate the implementation methods then you need to have you own identity what you are trying to do. I might post a lot of differe...

[quote user="serenechaos"] If I were in your shoe I would take make as you wish but wish a slight correction:

Romy:I hope you go ahead with your project of installing the horns in your attic as you are probably the only person who might pull it off, but if my opinion was solicited, I think you would be very ill-advised to do so. Firstly, the costs involved a...

I moved your post into a separate thread as I think your post about a subject, contrary to the thread where it was moved from was about the virgin fantasies… [quote user="Ronnie"] I thought I built almost copies of the Macondo upperbass horns, yet I'...

[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 ...

Finally, it has happened. Sound. Two weeks ago I had a couple of mates help me carry up and install the first DSET on its pedestal on the horn stack. It was quite a bit of effort and three were definitely required for the heavy but delicate operat...

[quote user="Romy the Cat"]This is all because you are a primitive person with very simplistic and amateurish understanding of many things. You need to learn from much more sophisticated people, of cause I mean myself. Take a look: I do not run like...

[quote user="Romy the Cat"]However, you need to find out how much power and how much gain you need for you subs and your room. Borrow for someone any 6C33C and measure how far the 6C33C will be from class A2 at a level of max tolerable bass in your r...

"another big selling
point to me was the 505 being a low resonance compression driver..
there just aren't many drivers with a resonance in the 80 to 100 Hz
range like this driver... I have just begun my playing, but am already
quite taken by it.....

I was very sorry to learn that Fane has closed up shop.
Their very client-oriented service was totally out of time, even for England.
About a year ago, expecting a big "NO" for an answer, they actually agreed to fire up the "assembly line" (?) ...

I do not think my topology is relevant, (it took me 3 months to get my studio horns to sound right 20 years ago so I expect this again, it is a mix of mjlouspeaker transmission lines and this midrange m4 trial. And it is actually 2 systems I am w...

[quote user="jessie.dazzle"] You might be able to get away with a bit less; if I remember correctly, my calculations at the time (based on the above driver) yielded a theoretical ideal volume of something like 23 cubic feet (sealed), so still not...

[quote user="Murataltuev"]Is any
technical background behind the statement that 4" driver can't
operate in 300-1000Hz because resonance is too low ? [/quote]
Well, you need to define what does it mean “can't operate”? Anything can operate anywhere...

[quote user="Kcct82"] Hey guys, I bought the Goto 505TT with S150 horn brand new over 2 years ago. Guess what? I'd still be in sonic shit if I followed the 200-1000hz "recommendation". The 505TT does not perform well below 400hz and when I final...

[quote user="IslandPink"]Do you favour the tweeter horn to be placed at the top, above the mid/HF horn , or in this situation place the tweeter between the bass/mid horn and the Mid/HF horn ?
To clarify -Bass/mid is a rectangular Tractrix with...

Jessie, a few comments.
The back chamber mechanism is good. Are you planning to do the same in the midbass horn? Since you most likely will not drive your upperbass all the way down I think that the back chamber mechanism will be more effectiv...

By “midbass horn” I’m talking about a horn with about a flare frequency of about 60 Hz, to use with Fane 8” drivers, to start with.
(Was planning to use this horn from wherever it sounded best, trying for around 80 Hz to ~35...

[quote user="Bud"]You need to find an individual who can design series crossovers. Both JBL and Altec used these, because they sounded best. You will need to look for an individual near where you live because they will have to test the drivers as...

[quote user="drdna"] So, my thought was that below 35 hz, there are many ways of thinking about amplification. Some might say SS amplification is helpful due to power demands of horn loaded 18" woofers. To use 6C33 might be a trade off but I do not k...
