    I liked almost every AMT speaker at a HT show so I figured I'll give them a try. Many options here:
    Above the planar horizontal
    side of the pillar crossfiring
    on axis and BG planar crossfiring

    I'll do the usual: FR, some polar-ish plots, HD , SPL

    If I like them I'll get another pair and stack them.

    WT2 results:
    Unit 1

    Unit 2


    The WT2 was really confused with unit 1. It gets to 16khz or so and thinks that's the FS, hovers about for a while then gives up lol

    Low LE, and ruler flat impendance. Not much else matters or can be derived.

    OEM stats for Scan for now:
    http://www.scan-speak.dk/datasheet/pdf/d2004-602000.pdf

    The Scan has a range of 3-14ohms in impedance compared to 4.25-4.35 ohm on the Airborne. The LE is also four times larger than the AMT's.

    The Scans blew up so there will be no TS parameters for them. I did get distortion and output readings before the incident so there will still be a comparison.

    Subjectively the AMTs sound amazing. A bit fatiguing maybe, but I haven't tuned them yet. I could not mount them vertically as the dispersion is much too narrow and the slight angle the pillar has is enough to shut the driver in. These are very directional. Next I mounted them horizontally and the dispersion is much better that way. The width of the AMT is the same as the width of the planar. This makes for a Geedes like dispersion matched but controlled setup.

    Can you please make some polar response plots for the AMT? Vertical and horizontal
    Very interested to try these especially for the price...

    Thanks,

    Do you want to see what it looks like in the car at some random points? Otherwise, the AMT has been tested in VC mag. The polar plots on the narrow side look comparable to a 1" dome. Basically, it seems to start beaming at 15,000hz or so. The longer side is very very directional, heavily beams from 4,500hz on, basically like a 4" mid. Here's the VC mag: Voice Coil - Voice Coil May 2012

    Other things to take away from that test that I really liked: Very low distortion 2.2khz and up, and all 2nd order as well. 100db or so 1w/1m sensitivity.

    I did take it down 8db or so compared to my 3/4 dome and it's still a bit too loud. The build quality is so-so. Some of the pleats are bunched together on one of them. One of the terminals broke off already. It's hole punched and a bit of pressure gets that lose no problem. Otherwise I like the grille, faceplate, some of the coating on the back (although it still stinks) and other machining.

    Interesting... Thanks for the test.

    I'm trying to figure out how to use one as a center channel tweet. Maybe flat aimed towards the passengers with the longer side parallele to the floor.
