Hi Folks....im trying to track some info on a medium sized JBL hifi cabinet,circa 1972-73-74,it was a moulded plastic affair,with rounded curved corners,and had (if i can remember) a 12" and a...
I have all 3 of those drivers here,and of course all produce a different type of sound,depending on the type of cabinet...if u have the space to build a large cabinet,its worth trying an E155 18,with...
Just to add my 2 cents....recently removed a couple of K140 `s from a stage monitor that had aftermarket recones fitted (ribbed cones,black dust caps)...they sounded truly awful...weak,thin and...

Thanks Zilch,i always need those bolts,you would not believe how hard it is to find them here in the UK.
silly metric system we have here.:banghead:
Yes,the 4520 seems to go lower,and a little more efficient,you can use 2 4530`s placed together,as they acoustically "couple" quite well,but the 4520 is the ultimate in deep chest thumping...
Before your Dad starts to build some,you might want to try and find a 2nd hand pair,as you can buy these very cheap now,probually less than it would cost you in materials to build them!...they often...
hi Guys,anyone got a spare spring loaded black terminal for an 075? the top part (the small metal clip with the black cover) is missing from one of mine,i have the spring,just need top part if anyone...

I have E130`s in the 4560 cabinet and they sound really nice,but building that as a DIY project might be tricky due to the angles and curved surfaces of the horn,have a look on Ebay,as u can buy...
Yes,thanks guys, success HP! i gave it a good sharp whack as u suggested,and its now apart...was actually a fair bit of corrosion on the retaining screw thread when i got it out...anyway,all OK...
Hi Guys,a really silly yet annoying problem,trying to change a diaphamm on a 2402,cant undo the rear screw securing the phase plug,if i put any more leverage on it,its going to shear the screw...
Ok John,here`s the story....this driver belongs to a freind of mine,it was attached to a 2350 radial horn,and left pointing horn-mouth skyward in a leaky bus for a week after new-years eve before it...
Yes,thanks for the input guys,i found this cutaway photo of a 375 which gives a good clue to where the internal pond would be!..so i think maybe the tiny-hole approach would be the best bet.
...
yes,thanks Rob,i have taken the diaphramm out and dried all that,but can hear water sloshing inside the pot,behind the pole-plate if i shake it.
Hi Guys,ok,does anyone know how to take the driver apart,(the iron pot/magnet assembly)as i have one here full of water (dont ask!:banghead: ),and i cant see how to get it out,u can hear some...

Many thanks,Ian. London.uk.
I have come across lots of these 2x18 TCB subwoofers for sale over the past few years,mainly ex-club and install,and funny thing is,they are ALLWAYS either empty,or blown,or without the original...
Does anyone know if MWA Speaker Parts in Arizona are still in business?i emailed them 4 times,no reply?:blink:
Thanks guys,i will try emailing them.:)
Ian,london/uk
i tried Great plains audio,they dont have any...im sure someone must do a re-cone kit for these? there must be litterly thousands of these old Guass units lying around blown in peoples garages and...
hi Guys,i know its not JBL related,but i need help in finding four recone kits for Gauss 4583 15" drivers...they dont have to be original,an after-market kit would be fine....
