The Sound

The listening session done by both playing home theater and music mode.  Together with several other friends we were stuck by the system ability to bring higher resolution sound..

At the beginning we were watching Zhang Yimou The House of Flying Dagger with the marvelous scene Bamboo Forest Fight scene and The Echoes Games scene. The sound was really stellar one! the whispering bamboo, the flying sword, the echoing drum coming from all around the room but not the speaker themselves!

At Need for Speed movie final race scene the sudden thundering sound of muffler exhaust screamed the room as if real car entering the room.

At the Dolby Atmos Amaze Scene we got surrounded by various sound from side, front, behind, above us. Very amazing experiences!

Credit to combo between Accapela Campanile (Ion Tweeter and Horn Midrange) and German Physiks Carbon (omni directional) which is very dynamic and credit also to the amplifier which can control the loudspeaker with great linearity and high in signal to noise ratio.

Then I try to ask my friend to play some musical content that I brought which is Mantovani Orchestra. This time we played Chariots Of Fire and Amapola. The music was so marvelous with 3D and holographic imaging. As if we were transported to the best concert of Maestro Mantovani. Then  we tried to listen to The Butterfly Lovers Album which is awesome album that fulfill my emotion with the haunting sound of string instrument.

The ultimate experiences finally comes with Blu Ray of John Woo Red Cliff an epic chinese war story full of battleship and infantry war. We just transported into the war zone with all of dynamic impact and transient. I think I should wear my own armor shield. Whew...

The Conclusion

What an astonishing system! very realistic and incredible in sight and sound.

DIY Loudspeaker of VD Signature Aurel Bryan

This time I want to tell about the project of full range drivers as the main driver plus ambient tweeter to enhance extended high. Oh what a lovely project...

Enter Aurel Bryan Full range driver (USD 130) and Eton Dome tweeter (USD 199) as a great combo of this project. For the info Aurel Bryan is 8 inch and the specification are 40-18KHz and all made in Indonesia

The crossover cutting point is 12 db Butterworth at 12,000Hz and beyond for the Eton tweeter. All the frequencies below that goes to the Aurel Bryan Full Range. 

The enclosure itself is sealed one and the  tweeter is physically time aligned based on the position of the full range driver. The purpose is for solid imaging and staging.


The result is adorable and relaxing sound,  lifelike voice, good and stable imaging and staging. So happy with the result!Kudos for Mr Rudy Gunawan as the maker of Aurel Bryan driver

Best Regards

DIY Loudspeaker of Kaymee RFE-1

Kaymee Audio RFE-1
This is another Standmount DIY Loudspeakers Project as a result of great collaboration between the team of Kaymee Audio. 

Inspired by Ensemble PA-1 (which is my favorite Standmount Speaker). 

But unlike the original design, we use MicroPrecision Z130 Tex for Woofer (instead of Zellaton driver which is very difficult to find) and Scanspeak 9900 Tweter (instead of Hiquphon OW II) we also try to smooth out the front baffle in order to have less diffraction enclosure.

The All Indonesian DIY Collaboration

This time I will give my personal experience of DIY Collaboration between VD SIGNATURES, AMBITUS drivers and ANDA Amplifier.

The drivers came to me from a friend named David Karjadi which is the person who held The Indonesian Brand of Ambitus.

The specification quite good so I decided to make a DIY Loudspeaker together with Mr Fidy Purwoko of VD Signature. We have made some open baffle for midrange and tweeter in pyramid shape enclosure and for the  bass we decided to put the woofer in dual port bass reflex enclosure that tuned in 35Hz 

We made several test with various audiences the amplifier which being supported by  ANDA Amplifier (Blameless 2x100 and 2x150 watts per channel). ANDA in my opinion are clear, clean and powerful power amplifier with lots of headroom. The amplifier were made by Anistardi Sudikan and Daniel Suroyo (hence the name ANDA) and 100 percent made in Indonesia

We also use CD Player and Hires Source Player for the test using Sepanjang Jalan Kenangan CD from Sangaji recording and Lucky Sing Broery from Platinum recording. We also try Three Blind Mice Recording of Tatsuyoshi Yamashita Misty for the hires recording.

The combination of the system gave us solid staging and imaging and the proportional tonal balance and tonal accuracy. Almost every music we put on them could reproduce it beautifully with decent separation, spacious, but also neutral and musical. We were happy for the result of all Indonesian Audio Gears...

Best Regards
