righty ho, this is what has been going through my mind of late in terms of layout and operating priciples. the plan is very short on actual detail, the flares are not calculated etc, but you can get the idea from this. thanks again to nexus for hosting this picture.
basic points are as follows. the high and high mid horns are "floating" in the low mid horn mouth by being attached to the braces. unbolting these braces will allow access to these drivers and their crossover. to facilitate the use of a passive these two drivers are physicaly aligned within the cab, whilst the hf horn has to be slightly shorter that is no problem as the throw from the mouth will be unobscured by other cabinet components. there is a lot of potential for jiggling this around if we need to incorporate any inclination etc.
the floating mid horn may help cut down on diffraction wierdness, it may make it worse. as the low mid horn mouth is effectively the whole of the cabinet frontage up to the edges this should help the cabs couple when stacked. red bit on the back of the 6" is supposed to be a heat sink.
the 12" drivers are reverse mounted for voice coil cooling and to allow for an obscenely small rear chamber, the exact tuning of the bp-horn combo can be fiddled quite easily.
there is an easy dead space for handles at the top and bottom of the box made by the little seperator between the baffle and front flare piece shown on the picture, the side handles have been ommitted for clarity.
i also think that this is a good box size, big enough to house some decent horns with a bit of cunning but small enough to be manouverable. two will stack on wheelboards in a blatant copy of funktion 1 methodology. there is virtually no wasted cabinet space.
there's a bit more to it than that, but for starters i'm quite chuffed.
james.
