Another rental, another 200+ satisfied people :-)

[Robby Hoinsky]

I rented out my system to a party from University of Hartford. 200-300 people there this time. The room was an echo chamber, but it actually didn't sound too bad for music once I got used to it. I measured the RT at about 1.5 Seconds. I used a pair of melded otop 12's for mains, jack 12's for side fills and a 2x3015lf ported sub.

Just look at all these smiling faces -

Can you correct for reverb? I have run into this many times, and always thought about trying to help it, but I wasn't sure how.

Vertical tweeter arrays do so with pattern control that limits early reflections.

+1

the tweeter arrays make a massive difference in directionality and therefore inteligibility of sound. I've used my system in venues I know to be acoustically horrible with other PAs, such as JBL, and been fine with mine. A good room is obviously much better, but the tight dispersion is a godsend. Even without the other advantages of BFD.

Interesting point on dispersion.... Does this mean it's probably better to run a straight array indoors and use melded outdoors or large arenas? Asking because I will most likely be encountering indoors with a packed space of 300 and less.

No, just the opposite. Outside, people tend to be farther away from the speakers - you can get away with narrower dispersion. Inside - they are spread out closer to the speakers - thus, wide dispersion is better.

I should have restated i meant tight vertical dispersion. The wide horizontal dispersion of themelded is great indoors.
The tight vertical dispertion stops the sound bouncing off the ceiling and muddying up the sound. If you look at the pictures above, you see that the ceiling is the only reflective surface that is close to everyone in the room. Reflections off the Walls are too far away to be a problem here, and the floor is covered in people absorbing the high end, so keep the HF from bouncing off the roof and voilà, crisp sound. If you used a standard speaker setup with 40degrees vertical dispersion and up to 20 degrees of that is hitting the roof and bouncing back, smearing the sound.

"I see," said the blind man looking at nothing!

Thanks, Dave! That is a great explanation. I am not worthy! [Where's the kow tow icon?]

is that not japanese? Not Chinese?

Both cultures have what we write as k-o-w t-o-w - the most reverential bow whereby one kneels and touches the forehead on the ground.

Actually, of course, that spelling is neither Chinese or Japanese but a transliteration of the sound of Japanese and Chinese pronunciation into the Roman alphabetic script.

Modern (simplified) Chinese is: 叩头 which literally means "bump" "head". I dunno the traditional or full form characters (used outside mainland China). [Mao Zedong 'simplified' Chinese characters as part of the communist modernisation programme so places like Hong Kong, Taiwan, and Singapore still use the older "full" form of the characters.]

Dunno Japanese characters either. Sorry.

Ok..... now I get it. Makes a lot of sense now. I'm always impressed with some of the details of venues you guys are doing. This is really motivating me to put together my own rig.
