Time fly. This coming July would be 1 year after I introduced Bullet Bazooka, Magic Bullet and other high quality tweeters. Before I installed good tweeters in my new BH, there were few debates whether good tweeters help to improve bird population. Nevertheless I have tried myself using good tweeters at my new BH and the results are good.
Now I would like to introduce 2 new horns to use with Bullet Tweeters. The horn from the same Bullet Tweeter Manufacturer. Actually, the new horn is not really new to me. If you click my old article below, I have been using VM-600 a year ago for my external sound. The material use is High Impact ABS, same material as Exponential and Bi-radial horn. At that time I did not introduce to my blogger as the price is 40% higher than Exponential horn.

Finally I managed to find a reliable US source and I already ordered a few.

Introduction Price - RM35/ea
2. VM-600
Dimension: 12" x 4.5" x 5"
