I bought 4 subwoofers and I'm absolutely not doing a DBA! Hah!

@scotandholly, I’m pretty sure @erik_squires made his design choices with eyes wide open, and I respect them.  If you want to persuade him to go with a distributed multi-sub system, I guess you can try. 

(To avoid possible confusion I don’t use the initials "DBA" because they can also stand for "Double Bass Array", which is a very different approach.)

I'm teasing the DBA group by calling this a subwoofer project.

It's really a 2-way to 3-way, passive to active project specifically tailored for my living room. 

@audiokinesis, definitely not trying to persuade anyone, of anything. Just curious and wanting to add to the conversation. Certainly the big guys like Wilson, Magico, YG,  etc. have the same approach. But digging into the weeds, I thought you guys had a better idea, idk?

@scotandholly  There is a lot that went into this that has to do with my aesthetics, complete lack of willingness to add more bass cabinets and wanting to take the positive experiences I had with an active center channel and bring that over to my main speakers.

So, if you look at this from the perspective of "how to add more bass" this project won’t work for you. 

For me this checks off a lot of aesthetic and personal interest boxes.  Conversely I’m not about to try to convince anyone this would work for them.  Just sharing in the fun of the project.

Otherwise, those who insist I need to do DBA can look at this live picture of me and sigh away.

@erik_squires Your configuration reminds me of my Verity Audio Parsifal Encores which have an additional option of being able to position the woofer module so that the driver fires forward or to the rear depending upon which sounded better in the room.  Both cabinets are sloped as well.
