Initial impressions of the Seas Neos are two thumbs up //content.invisioncic.com/y282845/emoticons/2thumbs.gif.fdc3ba010dbb42b61704534b46d02fe4.gif
The sound is accurate, 'airy' and they are a good match to my articulate midrange and midbass. There is no harshness, but they can be a little bright. They are sort of neutral on bad music....detailed, yet somewhat forgiving. Nothing an EQ can't fix I guess. With high quality disks, they can really shine.
At high volume, there is some sibilance...especially with female vocals. Go figure. My test for this is some selected tracks off the Celtic Women CD. Lots of chances for ringing, harshness, and 'shhhh' and 'sssss' sounds. Overall they did quite well, but not perfect.
I currently have them HP at 5kHz @ 12dB/oct. I did try them in a two way with the Lotus Reference mids and they sounded best at about 3.15kHz @ 12dB/oct slope. I don't remember the other x-over points right now...but I think I have the Usher's LP at 4kHz or so.
They are mounted exactly where my Dyn MD100's used to be in the pic below....angled about 30* up from the dash with the left tweet at 30* off axis and the right tweet at 60* off axis. Together they are aimed at eye level directly above the front edge of the dash.
Dispite the poorly thought out design, for 28 bucks a pop you can't go wrong.
