First we determine their flight path and then we open an entrance hole which will be facing that path.
Due to the possibility of polluting the sound we try to block the sound by erecting three walls around the hole turning the side entry type to top entry type.
So far the modification works is running perfectly as planned and hopefully it will be up and running before the CNY.
Meanwhile the tweeters installations started yesterday with about 150 tweeters being installed and wired.
Originally this BH was with about 50 internal sound tweeters but now we increased it to at least 200 tweeters. Main reason being those birds loves to stay at these tweeters.
The type of tweeters chosen were the 2"X5" and they were installed in a standing position i.e the 2" side is on the wood and the 5" will be the standing upright. The location of each tweeter need to be precisely located. The best will be at about 1.5 inches away from those 90* corners.
To increase the number of tweeters inside the BH we installed about 30 cluster tweeters each with 4 tweeters facing the opposite directions.
Each colony zone inside the VIP room will be provided with a set of 8 tweeters arranged like a chandelier.
Looks pretty well and today will continue with the wiring and finishing up the plastering of the three walls acting as the top entrance hole.
