  • Coaxial MT speakers w/ Separate Woofers . . .

    I have played around with car audio coaxials (Late 1980's JBL Studio Monitor 2 ways for car audio I have been dragging around since then) recently sitting in a small vented cabinet crossed over to a 12" paper woofer (Radio Shack) in a 1.6 Cu Ft cabinet and found them to be very inspiring with a little EQ applied.

    The point source nature and timing/depth of sound stage has me in its grip.
    The frequency response leaves a little to be desired but I want to continue experimenting with them.

    I find the availability of home hifi coaxials lacking in the marketplace and think that a MT cabinet with some better drivers once separated from one another and utilizing some DSP XO's can yield a good setup.

    The QTS is probably kinda high so what sort of small cabinet would be best for them?

    Thoughts?

    (you know I am going to do this regardless).



    The 12" woofer is crossed to the Coaxial with a PE XO at around 150 Hz.

    I've been playing with a coax for the exact same reasons. Just use the TS parameters in your favorite box program and shoot for a sealed box that's flat to half an octave below your cover point. Half an octave is enough if you use a LR48 for the xover.

      You might try mounting the coax in an open baffle, that is more or less how it is designed to be used. There are some benefits to an OB for midrange, first on my list is no reflections from inside the cabinet...
