Ok, Andrew, this is allergy something. I would highly advise you in future before you post any discrete updates, questions, and ideas about what you to inform about the holistic objective of your project, sort of a view from 50.000 feet...

Jessie,
I was about to replay to your post and suddenly John Hasquin posted his reply that said exactly what I meant to say. In fact he has much more credential to assess the validity of you attempts then me as he actually build the horns. In additi...

Since the “no tilting rule” is one of the Macondo’s Axioms: (#2 - “All channels shell have strictly parallel axis”) then I would like to defend it.

So-called omnidirectional sound (of course here we are talking only about 360 degrees within a two-dimesional plane) is framed in the concept of emulating the microphone. This makes no sense to me, since it, firstly , fails to emulate the microphone....

[quote user="rafaroxlm"]As you may know the 7788 is a high transconductance pentode which should in theory be able to give higher audio resolution than say 12AX7, 6072 tubes in tube mic pre designs. On search here the 7788 was mention...

Here are some commentaries regarding my “End of Life" Phonostage.
The name of this phonostage derives from many factors. I am forty, winch it more or less a half live and in the first half I was playing a lot with different audio toys. The last 10 y...

Hello Haralanov,It is hard to talk about sound, and define points: this is why the post is so long.Most systems I have lisitened to that measure a flat response have exagerated high frequencies and usually the midbass is a little shy, this might be ...

[quote user="hagtech"]First, it seems like the tubes are starved. They are running very low current. The 12AX7 is also at low voltage. I'm guessing they are running at about 0.3mA at 65V plate. This operating point is way down...

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

In my post above I have mention that Srajan is in a way a brainless parrot that repeats the heard and has no ability of desire to understand what was the noise about. His comments that 6E5P and E810F are “close electrical” is a good indication how it...

Sorry for the delayed reply.
Oh yes. 50Hz is possible ; )
Fs of the driver is measured at 32HZ matched for both channels.
As for a smaller driver, the smaller throat, keeping the "same" length for practical reasons wouldn't load it suffi...
