West Point is the premier Army collage. Located on west bank of the Hudson River on an important plateau, it has always been a strategically important part of our nations history.
Cadet Graduation in Michie Stadium
I just got the opportunity to travel to this beautiful place to do a check up on the football sound system.I was not part of the original install so this is my first trip out.
The drive up from Gotham is absolutely beautiful. I can only imagine what its like in the fall.
I figured this would be a quick trip, with a basic system check and back to Gotham. Boy was I wrong! Four of the six Mid/High speakers had problems and three of the six Woofers were dead! Ouch!
If you have ever wondered what is inside the scoreboard, here is an inside look.

Contrary to popular believe, the drivers I use, (drivers is what we call an individual speaker in a lager speaker containing multiple drivers) is only 6.5″. Its a real myth that bigger is better.
This is the view of the 6.5" Mid range drivers
What is different about my speakers from your speakers is the quantity of drivers. You have one, maybe two drivers in a single speaker. I have at least 5 drivers (my smallest), up to 15 drivers (my largest).
My speakers produce between 133 dB to 144dB. A jet engine is about 148 dB at take off.
Turns out when all was said and done, I had three bad Woofer amps, One blow High Frequency Driver and some bad pins in connectors affecting the rest.
The High frequency driver is called a compression driver. This is very different from a “tweeter” that you have in your speakers.
These are the compression drivers. They provide the high frequency's.
You can see in the photos it is a lager magnetic assembly with a VERY thin titanium diaphragm to produce the sound. This type of driver is VERY efficient and when coupled to a properly designed horn will make lots of noise with very little power.
Just a quick peek into my world.
