hi,
i've had Scripts for my side sourrounds and rear surrounds for years. while the positioning is precise, the sound is very pleasent and if you want a near seamless match to your other stats, then this is the way to go.
you are bang on in your assesment that the panels are close to the wall - only about 6-8 inches - and Roberto is right in pointing out that the panels are quite small but paired with a cone speaker that handles much of the sound "power".
keep in mind that the Logos center channel - what some call one of ML's best center channels - only has 4" of space behind it's stat panel. many people would not trade their Logos for another center channel speaker due to the presence of human voices created by it. now how can that be?
For me there are two aspects of electrostatic speakers that make them magical - the soundstage and the realism. My CLS make a piano sound like a piano, makes a voice sound like it's next to you, makes a doorbell have the dog wander over the the entrance looking for a visitor...
but the CLS also create a soundstage that spans from the to right, from top to bottom and from back to front. this soundstage is affected by space behind the speakers more than the realism of the sound is affected by space behing the speakers.
Surrounds (Scripts) and centers (Logos) are not creating a soundstage matrix but are instead handling a single discrete channel. Because of this, the soundstaging requirements of the scripts are minimized, they are being handled more by the Dolby/DTS processor driving the speaker. That soundstage pan of a bullet whizzing from front to side to rear and then past me is not a product of the soundstage skills of my side and rear scripts, it is fully a product of my 7.1 processor and the production 5.1 mix.
The same is true of my CLS fronts when a car drives from left to right. It is the mixing and processing that creates the illusion - although the CLS certainly help a bit
now, when i turn off the blu-ray and switch the processor to passthrough analog and source things from my turntable, that is when the CLS soundstage shines, and the 4 feet of air behind them help to create the magic of a stereo experience.
so, in summary, in my opinion the Script is mounted too close to the wall to provide adequate soundstaging when used to create a stereo image - hence the floor mount version that ML created. That said, the Script does provide a great little panel based surround that matches well with other stats in your system.
