The ideal width for our 120Hz line array is about 39”. In theory a flat 39” baffle will support our line array down to about 120Hz without baffle step or cancellation. That creates other problems along with being too wide for most home system. So we folded the baffle into an asymmetrical “U” shape. The inside of the back side is shaped to minimize cavity resonances. There a bit more to it but that’s the basics.
Hi Mike / @arion ,
I’m familiar enough with dipoles to understand the convenience of the U shape. I’m just dreadfully curious if you ever had flat prototypes and if so if you felt they were worth the excess floor space.
I’m asking in large part due to the very positive experience I’ve had listening to the SF Stradivari Homage and some gomments Troels Gravesen has made about how they seem to ignore the room they are in and impose the acoustics of the recordings.
Best,
Erik
