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 Final Product and the stand

The result is superb imaging and staging with proportional tonal balance! Large and 3 dimensional sound...

We are so happy and actually we want to build another one like this. Cheers

The Philosophy Behind Kaymee Audio AMT-1S

 The philosophy of AMT-1S actually has the same meaning as the word amities  

1. friendship; peaceful harmony.

2. mutual understanding and a peaceful relationship, especially between nations; peace; accord.

So this is the loudspeakers which build, listen and enjoy because of peaceful harmony and friendship around it.
