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

@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.

@jc4659  It's quite likely I've seen that before and it's stuck with me.  Unfortunately that (relatively) ugly plate amp is not going to want to be seen. :)

@erik_squires seems like lots of fun.  Thanks for sharing.

At AXPONA, SVS was demoing their surround system.  Sitting down. I felt the bass in my body and it shook my clothing. Not my cup of tea as I like crystalline highs and involving midrange.

Speaker and room coupling, haven’t seen your room treatments promoting lately which is important without overdoing it.

Lol @erik_squires not only are you razzing the dba crowd, but also the passive speakers only crowd. Good on you for doing what works best in your setup. I recently upgraded my subs to a pair of Rythmik F8 and absolutely swear by it. Small, light weight drivers in a sealed box to pair with my sealed box monitors and a high pass filter to keep everything separated. As for isolating the monitors, Isoacoustic Orea have worked really well for my setup. We want photos when things are up and running.
