Testing midrange drivers, from mid-priced to cheap

Hi,

Recently I have made a comparison of several mid ranges I have had been testing.
Test setup consisted of Dayton EMM-6 condenser microphone. Distance to driver was 35 centimeters. Drivers mounted in boxes between 2-5 lliters each. Measurement level was 2.8V which equals to about 90-92 dB. A small chamber was made by using a blanket while attempting to reduce interaction with the room. Contenders :

1) Scan speak 10F/8424G00
2) Peerless fsl-0512r01-08
3) SB Acoustics sb12mnrx2-25-4

As it can be seen F10 and fsl-0512r01-08 are in a similar ball park. F10 looks to have very good distortion figures, while, suprisingly, FSL-0512r01 burst decay looks somewhat better.
At the end of the line follows SB acustics SB12mnrx2-25-4, showing significantly more distortions.

Regards,
Lukas.
