Francis, what drivers did you settle on?

I know you have been talking about PD 1550 and RCF MB15n401. 
But Why the RCF? 5,5mm Xmax??

I am still looking into drivers, but 18sound 15lw2400 and 15nlw9401 still tickles my thoughts.

Thanks guys , I know it's taken some time ,but you know good stuff takes time.
i know one be asking themselves why I got 4 holes in each cab , reason is I don't want loose cables in the cabs , one speaker will be wired 1+1- and the next 2+2- , so when using amps like the X4 ,depending on how many we are using a 4x4mm cable into the first cab and links for the rest and no loose cables inthe box making all kinds of noise , painting starts in the weekend , spraybooth ready and 30kg of warnex ready, so more pics next week

Hey Father-Francis, can't send you a PM yet so I'll reflood this topic...

did the handles fitted nice in the hatch part? i did some calculations long ago for a pd1550 and if they were correct those two wont fit. but that was long ago and i am about to build one.

i thought also on placing two retractile handles in each side were the one that is not in the hatch is if i cant put the ones in the hatch

so build is long done we got 6 of these kicking about the place, anyway, in afew weeks we should be getting our hands on 4xphilishaves. so next up will be building a nice top for them , any ideas that doesn't cut off peoples heads like the old Jbl ,that martin used in the system before,need something that can keep up two philishaves per side

Beautiful woodwork there!! and they ARE killer bins !
In my experience... three is not high enough to effectively use Philishaves.
 Phillishaves will sound best one aside as they create a highly efficient point source.(stacking more gets exponentially more difficult and needs to be done vertically)
 Ideally, they would be tilted downwards as to not dispose of half of their glorious sound to entertain the pigeons.
The half sized "lady shaves" are a better format but do not sound the same as the co-entrant 2x12  philis ( a ground breaking design even now ! ) They both use  a "phase plug" ( it isnt ) which is basically the same as any compression driver uses to recombine in time the diaphragms area  and then squish it through a smaller exit into a horn . The drivers that martin used had a very shallow dome that fitted the (very heavy) resin "compression  bung".......
As with a lot of things we could say " It was so good ,they had to stop making it!! "  (edit,  sarcasm alert!)
There are far more practical mid hi solutions that will out perform this format , bearing in mind that height will give you more of an initial advantage , and wont try to kill you lifting it .

I hear what you are saying but lots of old pics and some new , i find more than one per side , here is an example 
I'd say if they did it then it shouldn't be a problem , 
the ones I looked at have phase plugs, and it's kind of a vintage rig we are putting together .

Cool ,I hadnt seen that before,some nice stuff there  , but that first picture shows what I mean height wise ,who wants a philishave full in the face and how far do you think thats gonna throw? and the lower hf boxes too. It would be ok for a kids party thoughTongue Build two more 215s and your above the problem Smile
An interesting solution for 3 x215s ,Martin did some tall 3x12" with a 2".Very retro !
