There are more than a handful of [op amps] that sound so good that most designers want to be using them as opposed to discreet transistors. Dave Reich, Theta 2009

The screen speakers look a bit low down towards the floor a few extra feet higher. The use in the home will be awesome sounding if you’ve got the room to place fronts in the room, otherwise you’d, wouldn’t have enough room to swing a cat around.



I’m baffled as to why Mr.6million dollar man, didn’t go with cinema pro.

Yeah I've heard and felt Martin Audio five-screen first-hand at the Empire Leicester Square back around September 2000 Gladiator and the Martin Audio was pants!

Thank god they have JBL back in that cinema with 56KW THX certification.

You wouldn't need to play it at the levels of cinema; those speakers have high sensitivity and would sound remarkable even at low levels a more, fuller sound would be noticed dialogue level will sound realistic also.

You fellows who are using big stacks (JBLsound4645 and Digital2004), what is your throw distance to your primary seating? The reason I ask is because the large stacks, being designed for long throws, are said to exhibit some strange issues in short throw situations. How does the stack resolve the issue of the relationship of distance between transducers and the throw distance? I would think that precise localization at home theater distances would be problematic. I also have heard that the big stack transducers comb filter each other and cause numerous problems at the crossover frequencies in short throw scenarios, but are not noticable in long throw situations. If the "home" theater is large enough, I would suspect that pro screen arrays designed for small cinemas would work fine. Just seems like the larger versions would bring problems. Tell us of more of your experiences with your systems.
