Yes, that specific vehicle had a lot of work done. It was also the first of it's kind, so the available options weren't as ready-made as they are today. But you entirely missed the point of that particular example. As long as you have room for the horns mounting them is not a difficult task, especially for a professional installer. Building for the 10" mids wouldn't be any more difficult than the work required to fit multiple drivers, as you suggested and as he was originally going to have done. And moderate tuning is all that's really needed to bring a horn into the realm of "sound quality" that would be satisfactory for this particular installation. I don't see how this route would be any more challenging than either the path he was originally intent on going or the route you've suggested, and the results would be better in just about every sense. Where is the downside? I see no problem to this, sounds logical to try out ... Impious, This was a great Moderators post, Logical, easy to read, and very nice straight on topic ... Thank you sir ... There was no need for ///M5 to be so arragant to me earlier, he could have just set back and let you answer. Then there would be no conflict ... Keep us posted Focalrock4life on what you do to your system ... Thanks, Randal ...
