I just got the 2x Sounderlink Neo3PDR from aliexpress and decided to measure some:
The drivers measured are:
2x Sounderlink Neo3PDR
1x BG Neo3PDR
2x GR Neo3 (no felt on sides, so more similar to Neo3W)
The setup is at 50 cm distance with SPL calibrated with an an SPL meter to -6 dB to be equivilent to 0 dB @ 1m. The drivers were measured in free air nude in dipole mode.
ALL drivers were driven with 1 2khz LR2 highpass. No individual EQ was applied for any driver.
All in all the Sounderlinks measure really well, they are more efficient than the BG and have comparable distortion but in my sample of 2 the consistency is garbage. If you run an active setup with DSP and one channel for each and you measure and apply EQ for each speaker individually then they seem perfectly usable.
The GR Neo3s are extremely efficient, but I did not expect them to have that much distortion. I was suprised hence why I hooked up my other tweeter. And even when reduced by -3 dB to 0.7W it still distorts more at the same SPL. One difference though is that I did solder the terminals on the GR but quick, carefully and with 1mm wire.
