The wait is over.....1851's have arrived

So at 37-38Hz, you were a 1/4 wavelength away from a corner. That's corner loading at it's best my friend!

The last two pages seem to have gone off the rails again, talk of 'box for box' and sound levels. Again, you're using specialised tools for a certain type of music; try a clash where the music being played is something like live metal bands, minimal techno DJs, or a jam session of jazz musicians. Then do the same to an audience of 2000 people, and see how it scales.

Again, it's not even really a competition because they're different tools for different jobs. We can all keep doing what we're doing perfectly well and get along. I certainly go to roots gigs for entertainment and I don't spend my time scowling at the system - I will however, if I feel something could be done slightly better, and the soundman isn't already set on his stack being the be all and end all of PA, offer some friendly advice at setup as to a few tweaks that may help.

horses for course ???

You just have to be physically near a boundary, as bass is omnidirectional. It does make a difference turning the cabs, especially going against common sense and pointing your bass directly at the corner itself, but it still has an effect just placing them.

I understand what you're saying about records, and to be honest I prefer something that sounds different and unique to something that just has relentless bass. However, whilst I can't be sure without knowing the other dimensions of the room, there's a good chance that you might have been a quarter, half wavelength or full wavelength away from other boundaries at other desirable frequencies such as 45Hz, 60Hz, etc.

This is what PA guys mean when they talk about room modes and such, and one of the reasons why some small roots systems seem to have power beyond their stature in one venue but fall flat on their face in another. Like I said, I wouldn't want to go up against a roots system playing dubs because for all the theory I can apply, I'm not doing it day in day out and as with so much in this world it's experience that really counts and you guys will always have the edge because you're ridiculously dedicated - hence my utmost respect for what you do.

That doesn't mean there isn't always room for improvement though, and it's a wise soundman who's willing to listen to and try a suggestion rather than getting defensive. That said, it's also the case that some of us 'regular' PA guys should stop acting like arrogant pricks just because we've read some books/whitepapers and attended a few seminars.

Very Interesting arguments about the 1851

what you reckon a pd1851 would sound like in a em quake mse118?...
