Using EASE (Enhanced Acoustic Simulator for Engineers) V4.2.1, we are able to create a virtual room that

is represented above. Using this room (speaker coverage model) we can show how various

loudspeakers will perform within this space with an “apples to apples” comparison.

We will compare a rendering of sound in a slice through the room at the average listener’s ear height –

we call these slices “Audience Areas”

First let us look at the Yamaha Wave Force (WF-112 x 3) speakers you are presently using. Our first

rendering will be 250 Hz Broadband – meaning we are looking at the direct sound delivered to the

audience areas from the loudspeaker from 250 Hz and up.

Notice the ‘hot spot’ right at the podium location.

Let us look at the rendering at 1000 Hz using your present speaker system

Now we will look at the rendering of 2500 Hz using your existing speaker system

This rendering using your existing speaker system is of 4000 Hz

Renkus Heinz PN12/6-4(T) with STX2M-94 Downfills Speaker System

Using the same room, we will now view the Renkus Heinz PN12/6-4(T) with STX2M-94 Downfills Speaker

System at 250 Hz Broadband – that is from 250 Hz and up direct SPL from the loudspeakers to the

audience areas

Let us look at the rendering at 1000 Hz using the Renkus Heinz PN12/6-4(T) with STX2M-94 Downfills

Speaker System

Now we will look at the rendering of 2500 Hz using the Renkus Heinz PN12/6-4(T) with STX2M-94

Downfills Speaker System

This rendering using the Renkus Heinz PN12/6-4(T) with STX2M-94 Downfills Speaker System is of 4000

Hz

Please note that all speaker systems were modeled in the same room. There were no changes made to

the speaker systems other than aiming them for best overall results. No Equalization or other

parameters were adjusted with the exception of the Renkus Heinz cluster which was turned down by

10dB to achieve similar SPL results at the audience areas.

All speakers are inserted into the model as the manufacturer has provided such measurements and

speaker parameters to users of EASE as specified by the EASE software provider.
