Hi sine143, Your suggestion to test in real half-space is a good one, and I did and do want to test the cab that way. It is just so boogerin' cold out that a) it's hard work to stay out there long enough to get a full set of measurements and b) I wonder if the temperatures affect the results. The mo...

Hi sine143, Good questions, and thanks so much for your help, no fooling. Here's a link to a chart showing the results of the very first test run weeks ago: http://s21.postimg.org/hoot9fahv/Omni15_Tallboy10_Hz_To20000_Hz_Sweep201312211642_2.jpg On that chart is a description of the test gear and env...

miked, thanks from my heart for your good words and wishes. Coming from you they mean a lot to me. Had the aforementioned shot in the neck, that seems to have accomplished approximately nothing. Primary care guy referred me to PT, and the bigtime neurosurgeon says surgery has at very best a 50% chan...

Thanks Grant and Bill, for helping me better understand how Behringer can claim that the INUKE 6000 DSP can produce 6000 watts. And Bill, thanks especially for your explanation of the dynamics of the Omni 15 Tallboy cabinet. I would be most grateful to learn more about the thinking that went into th...

88h88 and Tom, I really appreciate your good words and wishes. Hope the shot does some good: it did knock the pain down some, but the hand still doesn't work properly. The docs said that the relative success of the shot can only be evaluated after 2 weeks. But that hand works well enough to allow co...

And until the test results are available, the current State of the Project (with lots of lens distortion :?): bothboxes1.jpg That's Box 2 of 2 on the left :). When funds and time are once again available, Box 2 will be completed, with all the benefit of the learning from finishing Box 1. Should go a...

:hyper: Box 1 of 2 is complete! :hyper: 101 pounds (45.9 kg) of robust gear. It's always good when the product meets or exceeds the vision for it. I think we can safely say that this compact speaker system outperforms a legacy JBL 4663 (based on a Perkins bin), at significantly lower weight, and in ...

Here's the "tar-like substance" I finally used to fully seal the drivers and horn where they meet their mounting boards: speakerseal1.jpg This is nasty sticky stuff but it creates a great seal. Here's what it looks like before the driver is mounted: speakersealondrivergasket1.jpg When the ...

Here's the inside of the back access panel, for completeness: Crude, but one hopes effective .

Question: is this box overpadded?

Thanks, and all the best

Got a chance to devote a few cycles to working on Box 1 of 2 of the Omni 15 Tallboy in the 2-12" Configuration Project. And what a project it has been, wow. The product is starting to come together at last. Fixed most of the errors and omissions noted in the previous post. This cabinet most def...

Got clobbered with work of all kinds, so testing and completion of the one nearly complete Omni 15 Tallboy got pushed back for a while, and still are far from the top of the stack. But there are a few new data points (no photographs yet, but these will be forthcoming). Early testing results: 1) the ...

Thanks 88h88! Your encouragement means a lot, no fooling. As I keep saying, a good community has assembled around Bill's work. Of course Bill's plans, and his cutting jig too, get much of the credit. Nevertheless the builder has at least to try to cut things to the proper size, at the correct angle,...

Thanks miked! There is plenty wrong with it, as this build thread shows (although it is actually square, unlike the photos that always seem to show it skewed somehow). It has a vaguely ordnance-like appearance to me, that I like. Built by a complete n00b at cabinet building, it could have turned out...

Finally, some progress to report. Family matters took me out of town for a while. Got Box 1 of 2 fully stuffed and wired, functionally complete. All that remains is the edges, corners, and grille. May add 12" round steel grilles over the 3012LFs, all that would be required is some 1/4-20 nuts, ...

DJ, you are correct sir! And I did think about putting the tops on them like that, and still may someday, but not today. But they will look much like that. The one I'm bringing to completion already does, since it now has the 'mica on all sides except the front. The front is finished with DuraTex, v...
