Nothing magic about them at all. Most of it is about the HF end. When people see the cost of GOOD top end drivers that work to a suitably low frequency that's when the interest ussually diminishes.

I agree with James that Steve's introduction to them is a good start.

But the 1.4" CD and wave guide aren't brilliant in the range after 7kHz - but you will find this unless you pay some big $$$  and get better CD/wave guide - system EQ will be needed to get it to sound right - as with a lot of LA's out there
Don't worry F$cked up bigger gigs than this one...........

Hello,

I'm from the Netherlands and new here, excuse me for my bad englishEmbarrassed
The past 6 years I was thinking about designing and building a small line array.
This year I build the first prototype cabinet, it contains a dublle 8" RCF low/mid driver and a 1"Renkus Heinz compression driver. The wave guide is my own design even as the complete rigging system.
On this moment I finished 6 cabinets, the covering of a single cabinet is 15 degrees vertical and 120 degrees horizontal (-6 dB point) from 100 Hz up to 16kHz.
This system is powered by a Roland M400 mixing desk, a Apex Intelli-X processor and Lab Gruppen amplifiers. The sound is a real 'line array' sound, very clean, loud and 'in your face' and much better as I ever had dreamed offBig smile.

I designed it all by myself, it is made from air-craft aluminium (watercutted ) and black anodised.
The bumper is also my own design, made from steel and black powder coated.
The other 6 cabinets are almost finishes and waiting for low/mid drivers.

Ok, here some pics from earlyer stages:

12 cabinets is a lot of workDead almost all panels have a lot of strange angles.


Lots of brainwaves, sleepless nights and prototypes for designing the rigging hardware

Here the first prototype watercutted.

And a picture from a 4 cabinet stack without grilles.

Very nice! Did your waveguides work as designed the first time or did you do quite a bit of tweaking and measuring beforehand to get them right? Do you find it still sounds good with only two or three cabs stacked per side, or does it need the full length of the line for best effect/dispersion control?
