    Radian 1225-16

    Hello again,

    finally I got my hands on some Radian 1225-16 so I grabbed the 2426 and changed the dias,
    mounted them to the 2344 and made some measurement.
    Enough nice being said about the Radian dias, so I found a nasty peak just below 4k.
    My question here is could that be related to the back chamber?
    Comparing to the Fostex FD600 the damping is placed different.
    Right on the back cover the JBL and on the dia mount by the Fostex.
    Any suggestions? Can that peak be solved by damping?
    Would like to know before heading for a R-C link. Get the basic right at first.
    Also looked for xovers but that seems a stoney field to dig.
    The l-pads of the 4430 were just a bit to much to look at, is there a simple solution known?

    thanks in credit Roger

    simple 4344/45 xover needed

    Hello today,

    I found the issue for the peak in messurement of the 2426 with the Radian dias,
    The adjustment was incorrect. The other driver didnt have that peak
    so I keept searching, adjusted the one dia a little bit better and the peak is gone.
    I call that a win, problem solved.
    Sounds nice!

    The 2202 got a smaller doghouse and a highshelf with the dsp at the lower end.
    But taking the subs a bit to high, 160Hz, gives that sonor sound to voices in the lowend that I like.

    For future projects I am collecting some driver in the shelf.
    Got some stuff to build a 43XX monitor, not sure wich one.
    44 or 45 but while having the 2245 my only 15" is a K140 ready to be reconed.
    If I do it right the outcome will be a 2231a and not the 2235 needed for the 4344,
    wich monitor used the 2231a and wich components do I need for that one?

    Right now I'm waiting for some dustcaps to finish a 2122 recone what would lead to the 4345.
    Giving me the next question, wich one will feed my favour of sound.
    Is there a simple xover without lpads and charged C to get an idea? Those lpads get me puzzled.
    Had a messurment on the 2425 with the 2307 and was amased by the flat response.
    Gonna build a quick and dirty assemble to arrange the three driver to the upper end.
    Bass will be a front loaded Phonogen horn driven by a 2012h.
    2122h in the front with the 2425/2307 and the 2405 in a simple frame on top.
    Just for the fun and because its there. Need xover on that, would spare me a lot of work.

    So if anybody could help with that I will put some pics up sone. Thx
