Now, that cracked me up!

Those are fun track, especially LOUD!Originally Posted by Rippy;
If we knew what the hell we were doing, we wouldn't call it research would we.
I get the feeling that this man's "junk" is better than anything I'll ever own, or even seriously considering owning, in my lifetime!
No, I have not tried that. The main reason is that I need separate control on each woofer, and series precludes that. The upper woofer is rolled off at 300hz, to avoid interference and comb filter problems with the mid-range, while the lower woofer runs full-range.
No, lower woofers are running full range of course,crossing over at the JBL recommended frequency upper woofer is just a "balance" and "ambiance" woofer. The 300hz roll off was selected based on ambiance cues and room bass smoothness. I do NOT want vocals to come from the upper woofer.
Room fine tuning comes from varying the relative volumes of the upper and lower woofer, the volume of the stack relative to the horns, and the low bass roll-off on the upper; IE, if I need MORE 22 hz, I roll the upper one off a bit at 20hz, thereby reducing the cancellation effect. If I want less cancellation of room modes on higher bass frequencies, I can adjust the volume of the upper woofer. Then there are the time delays and so on to glue it all together. And, of course, there is traditional room EQ.
The trick is that its all variable, each one changes the other. It's much like doing the color convergence adjustments on old CRT color TV's; everything effected everything else. But, with patience, one could really make those TV's shine.
It will be two more visits before I consider it "dialed in" since the ear simply goes bad after a few hours of adjusting. It will tell you anything to get you to quit!
I have been getting great feedback from the customer and his musician friends, so I am sure I am close to what I consider dialed in. I will be doing some fine tuning around live piano and violin recordings when I go back. Main comments seem to be "what power and transparency!" "Wonderful timing" "Fantastic vocals" and "When's lunch?"
One guy did mention that I might need to get a little more rosin sound on the violin. And that the upper frequencies on the strings might be just a bit ahead of the main body. All that can be dialed in next time. Like I said, after a couple of hours doing sweeps, the ear loses a bit of subtlety.
There now appears to be an effort within Harman to make the new Everest II woofers available over the counter, possibly as soon as the first of next year.
I wonder if we ordered a bus load of them we could hold them to it...
The last time I ordered the minimum order of twenty-five they could only produce twenty (the excuse was that they ran out of parts)...
Getting our hands on some of those woofers would be great. So would getting my hands on some replacement super tweeters!
You caught it correctly, I do most of my sweeps at about 85db to 90db so that there is some room loading, but I am wearing heavy-duty hearing protection throughout the sweeping process. I misspoke earlier; it is the BRAIN that tires once you get to the active listening part. After a while, placebo effect kicks in and you hear what you want to hear. "Maybe if we tell him that it sounds perfect, he will let us go home and get some freakin' sleep." My mixing-engineer friends tell me it happens with them too. You get CLOSE, but fine tuning has to be done after at least a few hours break, preferably an entire day. And the client has to be fresh to, for his input on the final flavoring.
