    Hi from a new member.

    Hi, I've been lurking this forum and site, for years now. So...

    I am building speakers since probably fourteen years old. Projects were always cheap or even no budget builds, with a lot of recycling. A log time ago, when I was starting building speakers friend borrowed me one old speaker which looked a lot like D 130 but i am not certain if it was JBL or RCF copy of JBL, it was in pretty rough shape, and I have build several enclosures for it, and then had to give it back to owner. There was something special in that driver, that i never forgot.
    Six or seven years ago in one trade I have acquired two JBL K 130 driver, they were in very rough shape, so I reconed them with D 130 recone kits. Aftermarket ones. Blasphemy I know, but originals are so expensive.
    On this site I have found and build few bass reflex enclosures, but that wasn't it, so at the end I have built 4530 horns. Now, that was good. Well, almost good. Those horns goes down to about 60 Hz. So I have recalculated Jensen Imperial built in horn for D 130 and that should go quite flat to 45 Hz (according to Horn response) But, those are big and WAF is near the red area so I am thinking to build Hartsfield top loader instead. And that is where I stuck. Because it looks that plans for those speaker are drown on invisible paper.

    I saw that thread. Oldmics has put tremendous amount of effort in those so I hesitate to ask him. I also saw another thread, and I hope he found somebody to build those speakers.
    Thank You for help.


    There is a low quality video of my horns. This is first try, truncated tractix 300 Hz horns were made by me, and loading JBL 2445 drivers. Mounts for horns and drivers were not made yet so they sit a little bit funky on 4530. Crossover is updated since then, and now is; on D 130 third order 1000 Hz, on 2445 first order 1200 Hz and a L pad attenuator 15 dB. L Attenuator is bypassed with 3.7 uF capacitor in order to get out some hi tones. Crossover will be changed again probably after I get measure microphone.
