Value, Quality & Service since 1980
- Regina Catholic School, Iowa City, IA
- A somewhat unique problem to solve.
- They were complaining that they could
not hear very well in the visitor bleachers.
- Well, no surprise since none of the
speakers were aimed at the visitor bleachers.
- The incompetent installers apparently
imagined that the sound would know where to go all by itself.
- Also, all 4 speakers were directly
over the concession window, so people had to shout to order a hot dog.
- We spaced out the speakers and aimed
them all straight across the field. This reduced the volume at the concession
window and substantially increased the coverage to the visitor bleachers.
Original bad speaker placement.
At first this looks like it makes sense, but the sound
is going all over the place and NOT where you want it.
New proper speaker placement.
This arrangement projects straight across to the visitor
bleachers and still gives good coverage in the home bleachers and on the
grass field as well.
- Conclusion: The original installers did not have enough
experience to understand how sound works.
- They thought the sound should go here, and there, and
over there too.
- Actually, the near areas will hear it no matter which
way the cabinets are pointing, however, to reach all the way to the vistor
bleachers, they need to be pointed that way.
- ** Once you see and hear it, the physics become obvious.
- We also installed a digital remote control mixer so the
Athletic Director can adjust the sound from the bleachers or even on the
field. Inside the booth is NOT the place for the controls.
- * The old mixer was constantly being 'fiddled' with and
was never adjusted properly.
- Now it can only be changed if you have the password!
- The speakers are the overpriced Community R.5. (worst
name ever) They are about 1/3 of a good idea.
- We replaced the original 12" speakers with Eminence
Kappa 12", which improved the sound a lot.
- [They claim 90° dispersion, but the actual coverage
is much narrower, especially at a distance.]
- The horn and driver are just about useless. The driver
is far too small and not standard mounting so difficult to upgrade. (One
was blown and we removed it - you could not hear the difference so we just
left it out.)
- And putting the horn in front of the 12" is a bad
idea - it blocks a lot of the sound from getting out.
- The cabinet is 16" deep, however, the horn portion
is only about 8" deep, not enough to get good performance.
- The mounting yoke is much bigger than it needs to be.
The speaker will never need to pivot completely around.
- A much simpler mounting system could be used.
