Sometimes a good new driver will appear when I had never heard of the maker before.
In the 6/02 issue of HobbyHifi, the Neo3 PDR and the Neo 8 were tested. The Neo 3 has good frequency response and good disto.
The Neo 8 has increadibly low disto, second harmonic well below 0.3% for most frequencies above 1 kHz at 90 dB, third at or below 0.03%, fifth below detection (0.01%). Between 500 Hz and 1 k, second is between 0.3 and 1.2%, third still benign.
Resonance frequency is 200 Hz, step response looks excellent (perfectly aperiodic except for traces of the 200 Hz resonance). Waterfall just perfect.
Frequency response rises very linearly between 400 Hz and 10 k by 10 dB, but there is a 6 dB peak around 12.5 kHz. I am not sure how much of this is due to the infinite baffle with unknown rear damping and the microhorn they routed into the 19 mm MDF.
Except for the semi-nasty frequency response, the Neo 8 seams to beat AMTs like the ESS AMT-1 or the Eton ER4 because it goes lower, has lower disto and a better step and waterfall behavior. Only the Manger might be a little bit better in the very low frequency range, i.e. below 500 Hz.
- has anybody used this driver?
- what would be the easiest way to correct the very linear rise out to 10 k?
