What is "ARCS", and why would you pull down a W8 system??
Some time back, I had the pleasure of running the first W8 rig sold in Australia (up until the owner decided to sell out..... damn), consisting of 4 W8C's and 4 WSX's per side (also occasionly hired in extra WSX's as well as the W8CM and W8CT long throw tops). VERY smooth sound, and it was this rig that made me realise what a high crossover point (3.5kHz) to a compression driver can do for the smoothness of the top end.
If you analyse the W8's toroidal phase plugs, you would find that they present a fast initial flare rate rather than a discontinuity - a technique commonly used to give better top end loading to a wide band horn. I believe the plug geometry also assists in pattern control, but I would imagine it would be very dependant on cone/dustcap shape. I haven't really given much thought to this style of plug, as it would probably involve a LOT of experimentation.
The 12" section goes fairly high (750Hz crossover point), but doesn't get that low - around 150Hz is the lower limit, which narrows the choice of sub box. If you look at the W8LC line array box, the 12" low mid is on a longer horn and port assisted to get much lower - something I will be playing with as well.
Cheers
