    I've had these since new and only used them a few months active at 5k from a jl audio xd700/5v2 but I'm not doing them any justice installed in the dash and decided I don't want to mount them on the dash in the included pods which have never been used. Very nice tweeter IMO and not a lot of English info online but I believe there are a couple of reviews on diyma. No trades at this time as I already have way too much stuff laying around.

    ツィーター:Alpine DLXF-30T

    ・It is 3.0cm component toe eater, DLX-F30T of Alpine.
    ・I adopt coexistence "異径 dual voice coil" structure by the early start at the high level and wide middle level range reproduction. フラッグシップモデルにふさわしくリング振動板を常に安定して再生するバックキャビティ構造な どソフトドー ムの自然なしなやかさと、ホーンツィーターの応答性をあわせ持った革新的な構造のツィーターと なっています 。
    ・"The aluminum Lunt spacer" which enables certain installation. I fit the body suddenly and play a role as the stable base. The slant installation at the time of the setup is enabled, too.

    ・The back cavity structure that can keep a fixed atmospheric pressure of the rear of the vibration board.

    Specifications unit: 3.0cm .............................dual emission type tweeter
    Reproduction frequency band:....................... 3.5kHz - 60kHz
    Input biggest at a moment: ..........................120W
    Rating input: ..............................................40W

    dual emission tweeter

    Highlights:
    • Outstanding High Frequency performance
    • Neodymium Motor Structure with Copper Shorting
    • Dual ring radiator diaphragm (patented)
    • Non-reflective cast aluminum tuned air chamber to increase SPL and dynamic response
    • New Waveguide center plug (patented)
    • Copper-clad aluminum VC wire
    • Flat response well beyond 20 kHz
    • Low distortion
    Rather than a vibrating diaphragm like conventional dome tweeters, the large Ring Radiator tweeter moves linearly; this ensures low distortion and smooth response with no harshness. Dual suspension pivot points minimize distortion and maximize speed. An integrated Wave Guide provides optimized frequency response and sound dispersion. The back of the tweeter has a non-reflective cast aluminum tuned air chamber to increase SPL and dynamic response.The ring radiator tweeter, the same type you'll find in high-end home audio speakers, offers less mass than a typical dome tweeter, and its linear motion results in extremely smooth response. The tweeter's built-in wave guide helps to disperse the high frequencies more effectively. You can adjust the angle of the tweeter for best results in your listening position
