All of sudden I realize that my blog is very poor about pictures. In fact, I did not start only this server to make my blog site, but the other purpose. So I don’t need to care about it though it is not colorful or is not ‘catchy’. But it feel so lonely….
So today, I will show you my favorite speakers. Look at picture below.
This is just a speaker. No, it’s not. As you can see, shade on right is look wired isn’t it? Side panels of box is made of acrylic resin, so you can see the sound way by side view. You can also see opening in bottom of box, this speaker is called ‘back-loaded horn’ or ‘BLH’. The speaker is very small, compact, size is just same as A4. But sound is very powerful. Unit is 8cm with full range(monacor:SPH-30X), but back-loaded horn is designed low frequency to make louder, so you never believe in your ears when you hear it’s sounds. You never believe this small speaker could play so various frequency, especially low. Of course every things have own pros and cons, for this BLH, low frequency sound wave from back side of unit will delay a little bit. None of us could find this delay, sound way length is just 1m and delay is only 0.003 seconds.
