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.

USACI Indonesia Qualifying Round 27-28 May 2017

These are some photographs of  USACI Contest that held in Jakarta 27-28 May 2017 which I appointed by USACI Indonesia as one of the Judge of Sound Quality 2way Free For All, Pro 80 and Expert Class... It was a fun contest with lots of beautiful sounding cars involved. The participants were very serious in term of technical matters (sound stage and imaging) also on tonal balance. The result was fair, honest and consistent and the best one win. Thank you for all participants for such a great passion! Kudos for all of you

The Hires Album

1. Three Blind Mice - Tatsuyoshi Yamashita Misty 24 Bit PCM 192Khz
    This Japanese recording is one of the best in term of dynamic and ambience.

2. Beethoven Monlight Sonata DSD 1 Bit 5.6 Mhz
    An example how the good music on the good recording can make goosebumps!

3. Lucky Sing Broery WAV 16 Bit 44.1 Khz
    Indonesian singer that really has great voice and great interpretation of the music

I must tell you that in order to play the music properly you must make folder named music and put all the Hires files into it.

The Review
1. Misty feels like...ah that song with clean and detailed presentation, very dynamic and palpable imaging.
2. The Moonlight Sonata track is one of the best classical composition from Beethoven to make our soul energizing. On the Hires format this song is closer to perfection.
3. Warm and tender sound of Lucky make me want to listen to his voice more and more. Liquid, sweet and soulful. What a sound!

The Result

Pro:
1. Clean and detailed sound
2. Somehow the high is very extended 
3. Smooth tonal balance and great imaging

Cons:
1. Relatively high price tag (but worth the money)
2. Can not play DSD higher than 5.6 Mhz sampling

Now I can enjoy listening to the Hires music in my car. I'm so happy to have this as part of my audio gears. Thumbs up to Sony!
