Howdy All,To John Y,I also have both of those "top views" of the Metregon.As you can see by the attached picture the horn is not configured with the driver facing downward as those pictorial views suggest.Not to mention clearence is really close between componets.Both the one inch and two inch drivers face the rear of the enclosure.Also the N600 crossover was listed as one of the system options for installation into the Metregon in 1959 according to the SC 506 publication that I have.Now as far as machines are concerned I did price an original 427 AC Cobra by Shelby this past summer.WWWWAAAAAAAYYYYYYYY outa my price range.The repros are everywhere.The Shelby Mustang was bad but something about those Cobras.Best regards,Oldmics (who walks to the office)
