This BH just operated for 3 weeks which is located in durian orchard. There are 2 entrance for this BH, one is windows type while another is air well type.
Initially both entrance look like attracting equal amount of birds playing around the entrance, but now seems like air well type attracting more compare to windows type. I still need to observe before I can make conclusion. Both entrance playing different external sound.The sound system of this BH is different with the rest of mine which more complicated. It consists of internal sound, center sound, transit sound, different external sound for both entrance and hexagonal sound.While waiting for bird nest harvest, still got some to durian to eat.......really multi-purpose agriculture land, must fully utilise the value of the land as the land prices increase like hell.
Now I can concentrate more on this Bh as the previous one already stable.
There are lots of brands of tweeter or speaker in the market, which is better or good with reasonable price to use in BH. I will share with you in the future.
Do enjoy the pictures, especially the durian.
