I use Magic Bullet to play pulling sound at corners or entrance holes. The birds really enjoy the sound from this tweeter.
This is another sound playing by VT-25 (3x7"). The birds and "Cockroach" like it too. Don't understand why this unwanted guest come in so early :(
The data logger shows that the Temperature from mid-feb to early Mar at the high side. The highest is 30.5deg. If the temp reach 31deg, I might consider to use Thermal Paint on my roof. Btw, the rockwool that I use is the lowest density. I will choose higher density for future BH.
Humidity at the low side as I do not use any humidifier in my new BH yet. But soon I will start using a new Ultrasonic Humidifier from one of new supplier. I will touch a bit more on that in my next article.

Good job, WTG victor,
