In Reply to: Parts Express announces full line of NEO drivers posted by BDP24 on October 8, 2020 at 17:17:16:
There is an earlier thread on this as well as a few threads on Audio Circle. Guys on the AC are testing all 4 models.https://www.audioasylum.com/forums/MUG/messages/24/243852.html
I have a pair of the "wide" NEO8's that I am testing. Above 250Hz is the GRS NEO8 in a baffle with a side wing, below are OB/Dipole subs.
The bottom plot (green) is the best in-room response that I could get to date by just changing the shape of the OB wing and an XO.
The top plot (purple) is using 4 high and low shelf filters to remove the peaks at the high and low ends and flatten out the center positive slope. There are no frequency PEQs used yet.
They sound very clear, detailed and are very efficient (I have padded them down by 8dB). They have a THD bump between [250-500]Hz (second plot) and roll off early on the very top end.
THD humps between [250-500]Hz.
