Balcony Coverage of Centre Cluster

Click on the black dots to view the frequency response measured at these seating positions. Note the variations in frequency response throughout the seating area. Consider what this wild variation in sound quality would mean for the people sitting in these seats. These variations cannot be corrected through equalization since fixing the response for one seat would make it worse in other seats.

If you have Netscape 3.0 or later you can see a small grainy preview of the frequency response popped up in the JavaScript preview screen to the left when you place your mouse over the links.

Seat M16 | Seat M26 | Seat O16 | Seat O20

In the balcony in seat M16 you can see the big bump in the low frequency response caused by the lobe generated on the center line of the cluster. There is a 12dB bump between 500-800Hz and then a drop-off at 2200Hz and reduced level above 3000Hz. Seat O16 behind it has a similar bump and drop-off, but the bump is split and has a bigger bump at 1200Hz. Compare this to M26 off to the side which has a response which is virtually the inverse of the M16, this seat has a dip at 400Hz again, and a big peak centered at 2000Hz.
