    Re: MR994A MantaRay horns and 909-8A drivers

    TTBOMK when the amp power 'wars' began in the late '60s and drivers started burning/blowing up at an alarming rate to the point where folks started swapping in JBL components [at least around here] is when loading caps started showing up on all drivers that weren't built for the consumer market and circa '76 these were too in the few I have knowledge of.

    Did M14, etc., come with them? I only know the promo M19s I auditioned at the distributor did. My '71 808-8A prosound also has them plus back cover, ditto the '92? 909-8A pair a long gone now local bought at the distributor's ~closeout when they switched to B0$3 and I picked up the last pair of the so called 'Ultralites'.

    These came with both the loading caps and the back covers. I have no idea what the horns and drivers came out of, I just grabbed them because the price was right.

    Do the felt, remove the loading cap and change the diagrams and I believe you have a 902.
    Nice sounding driver.
    I have a pair of the same horns. Had them on top of the 19?s for awhile and I remember liking the sound.
    Play around with them. Try other drivers.

    Pascalite diaphragm and loading cap. Should be just about bomb proof.....
