but I'm not going to compete with "S2 people " Following recommendation of John Hasquin I ordered B&C 21EP8 -16 . I'm cured form Fane for a time being and don't have S2 but "obsolete " altec 288c 24 Ohm on 400Hz horn . I was counting ...

Jessie Hi, re question 1, drop Jon a line at Sonic, he is far better placed to advise you on the addition of new codecs and hardware , the 'early adopter' software is I believe $1000, there is a demo version but it cuts out after 30 seconds which is ...

PlasmaCuts what-you-will like nothin', clean as a whistle, and the system is portable (ie, the Mountain can come to Mohammed).Also, I see an interior mold and making the inside of the Big Guns' metal a little oversized, to allow the us...

What funny is that what you proposed was exactly what my carpenter suggested me to do as soon he saw my frustration with foam. In particularly funny that he used pretty much the same words. I got the 2” foam and 300 feet 6ga stranded cupper wire from...

Jessie, Unfortunately your images did not make and the most important dimension: the throat size is not visible. Will you go for 12” throat? Sometime I will do pretty much what you do, ironical using the very same drivers. I have a pair of AK154, a p...

I would like to point out to a very important moment that took place in here. I do presume that Jessie account is very accurate and the Teflon sockets were bad. I even presume that they were bad not only from the perspective of cooling but were bad s...

[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="guy sergeant"]One issue that I would consider is that the Tractrix profile supposedly does not lend itself aswell to extremely low frequency horns (being too short) as other profiles in particular the Hypex (Salmon) shape. [/quote]
Yep,...

[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"] 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...

Thanks, Jessie; for the benefit of others here I can confirm pulse-racing are excellent, just as Pete found. They still have his CAD file, so if you are happy with the bolt placement no need even to send them a drawing.What is definitely not excellen...

Yes, Jessie, in a way right – we align the summits to the same frequency from two drivers in the same period. Why he is right “in a way” in such case? Well, become in Jessie’s example there is an interesting hidden bug. I would like to offer everyone...

[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"] 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...

Over time I have observed that, in most cases, one quickly turns the corner from "enough' connector mass to suddenly arrive at "too much" connector mass. I started out with a cable clamp like Jessie shows for my 6 gauge "dedicated ground" wire for j...

[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.

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.

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...
