Re: Flanking Subs vs Helper Woofers
Flanking subs do not get a summed signal - They get the same signal as the main speaker they are flanking, with a low-pass filter applied. They're stereo subs. That's one of the key distinctions between flanking subs and more distant distributed subs in ...

Re: 4 Pi revisited first impression
Thanks for posting here. As I read your post, I remembered the days about ten or twelve years ago when many people on this forum were "doing their own thing" like this, maybe as many as half of the builders deviating from the plans in one way ...

π Constant Directivity Cornerhorn: Bass Bin Design Details
I did consider making the bass bin of my constant directivity cornerhorns using a folded horn, like the 12π hornsub. But upon careful considerations, I found a lot of disadvantages in that approach. These considerations are described in some detail in ...

Re: Speaker Stand Article
I consider the loudspeaker position and its amount of panel vibration separately. Loudspeaker position and direction determines the orientation of the forward lobe, and it also sets the position of the node that energizes room modes. This is true eve...

Re: 7 Pi Plans
You've got mail! Beautiful photos. Is that the view from your home? About your room, four feet isn't really enough of a corner to provide the best response, but you would still have the benefit of not having a reflection from the closest walls. A...

Re: 3Pi speakers - various questions
Can you put the subs just to the outside of the mains instead? If you put them in the center, they'll act as a single source. Three feet of separation isn't enough, except to smooth self-interference from nearest boundaries which you won't have becau...

Re: 3Pi speakers - various questions
There is only one place in the front wall where I can place the subs, if not directly below the mains... flanking the center line of the room, as shown in the pic below... I get only about 8" of usable depth, about 48" of width and up ...
