Have any of you tried Crown's new amp yet, and if so, your thoughts?

Re: A video about a HORN!

It would have been more interesting if they would have used a full (or even wide) range driver, given the lack of harmonics removing folds in the straight horn. Or broadcasted a lower frequency.

Yes, Bill, this is what we want!

Re: upstarts needing amp info.

... These parties will last for three days and the music will rotate depending on where we are in time, between night and day.... Don't bury the lede: WHERE ARE THESE PARTIES GOING TO BE?!?!?!? And how do you get invited!? :lol: Maybe you could testdrive someone's system, or likely, several someone...

Re: 6 Tuba 45s

Test fit the 3012s, all seems pretty good, though I will have to notch the door flanges, that's not to big of a deal. https://lh3.googleusercontent.com/FuT40HX6g63uPd4JrJQ4CN6Q5gkcG2C4hrnCPPxV_aQSRignG1HBCPBmjKlieIxy61Xx6mwfmIAKERJ6e25JmgJQ3Y1hVxn2msafuQZRy9rMw2V9hZdcZOjI0Mu73HTGCA41-4hSbw=w2400 To...

Re: T60 Limit

And what about the fact that folded horns remove said harmonics? Or is it moreso they reduce them to imperceptible levels?

Re: T60 Limit

The pipe fundamental is only a small part of what you hear. This charts the spectral content of an 8 foot pipe: https://billfitzmaurice.info/images/Templates/charts/Pipe organ spectral.jpg The 1st harmonic is the fundamental. You can see that the 2nd and 3rd harmonics dominate, while even the 5th a...

Re: T60 Limit

... try playing music that has sub 40 hz content with a T39 high passed at 45 and all you’ll hear is harmonics of course, because you’ve cut off the fundamental and it sounds like garbage... Shouldn't the folds of the horns in tubas or titans be removing those harmonics? Or is there just enough of ...

Re: T60 Limit

I'd be curious to try playing a 25 hz sine wave, with the highpass set to 24 and the lowpass set to 26.

Re: Compression horn tips, tricks

Well if you're going for gold in the weight savings exercise, build a small enclosure for the crossovers with a Neutrik input, and basically biamp the mains off of two outputs from said separate enclosure, that could sit on the floor at the foot of each tripod. Kinda silly, I agree, but a pound is a...

Re: 4 x SLA Pro, 1 x Wedgehorn 6 and 2 x Titan 39

You could bring a battery powered saw to the lumber yard (borrow one if needed) and use a straight edge as a guide. Make that first cut in each sheet, the width that you need for your parts. I had considered that and have been asking around for a portable circular. No luck yet, but maybe they'll le...

Parallel wiring half the impedance of the 2 drivers, add 2 ohms for the cab.
Lab 12 ( 12/2 +2) so 8 ohms.
Lab12c (4/2 +2) so 6 ohms.
Shouldn't that be Lab 12 (6/2 +2) = 5?
