[QUOTE="Peter van Gils, post: 202246, member: 3943"] Yes, the operating principle is different, though the advantages and disadvantages are similar: they (can) have good frequency response, low distortion and good impulse response. There is low sensitivity and low power handling for both on the downside. My experience (in theatres by the way): 1 cabinet sounds stunning, multiple gives you lobing. I'm using conventional tops with the upper top stacked upside down on the bottom top to get the ribbon drivers as close to each other as possible. I still hear the lobing when walking up the tribune. I need multiple cabinets because 1 cabinet (12" front loaded) does not provide sufficient output. Your line array top should be better at coupling of multiple cabinets: due to the AMT and the distance between the drivers. Funny thing is: I'm currently building your DIY mid/high design with 90x50 horn because I like the concept of having a single point source. Let's see what this brings... ;-) [/QUOTE]
