[QUOTE="Loren Jones, post: 2412, member: 829"] I am reluctant to post this for fear of exposing my considerable ignorance and inexperience, but here goes anyway. How much difference should it make if the woofer and port on a direct radiating sub cabinet are pointing 90 degrees off to the side as opposed to firing straight forward. In this situation the subs are sitting in front of a 3.5 ft high solid wall at the front of the stage. Passband is 25hz to 80hz. The reason I ask is that a musician member of our congregation asked me to try this out with our now groundstacked subs. Some members that sit toward the front of the room had been complaining that the bass impact was too much for them so this musician in the church begged me to try pointing them out to the sides to see if it lessened the impact at the front of the room. Well I humored him and sure enough in the first couple rows there was some noticeable decrease in the bass impact. I don't have good enough gear to reliably measure such a thing so I can only say that it subjectively did take some impact away in the front few rows. It didn't seem to create obvious adverse effects with overall coverage in the room. I wondered if most of the difference may be higher frequency stuff above the passband. The LPF is 24db/oct at 80hz but I am not sure of the topology. So what disadvantages are there to such an implementation. It seems to me the only time I have heard of subs not pointing directly at the audience it is in the creation of multi-cabinet cardioid arrays etc. Just by way of background the subs have probably about 45 feet between them at their respective corners in front of the stage. The room is about 100 ft square with a 28 ft ceiling and has a couple pie shaped wings out to each side. I am sure room effects predominate in this kind of a situation but I was just curious if there is any reason to absolutely not do this because it always does (fill in blank with undesireable effect that I am unaware of). Thanks for always teaching me a ton, Loren Jones [/QUOTE]
