Right now I'm playing with rear firing drivers. Since having had dipoles I really can't get used to box sound without it. It will be some time before I open them up and see what the electronics looks like, but I bought some Neutrik Speakon L8 male connectors to take advantage of the ZuB3 input connection on the back or the speakers. The AHB2 has Speakon L4 connectors on my existing cables; why not add 2 more leads per cable, see what we get?

There is plenty of depth to the room, but the sectional is too big to rotate the room and have my recliner in a reasonable position. I use the recliner a lot due to multiple spinal fusions.

I will never go back to Maggie’s after having these Zu's. And am experimenting with rear firing drivers to recreate the dipole effect of expanded spatial dynamics. So far a Fostex 4” Sigma works best, down to 200 hz. 

More pics to come as I add plinths and a final rear speaker design to the Zu's in a finished box.
