Awesome. From what I was told in this post
, the 328C's are an ideal match as they are almost identical to the SCS-8's, minus the mount-on-ceiling enclosure. However, the space needed above the ceiling for the crossover and backcan is something in the neighborhood of 12"+! So if mounting into an attic, no problem. If there's a room above your theater, that may post a challenge.
I was concerned about 2 things: cost foremost, and then above-ceiling space second. I eventually went with the 227C as it was less expensive and required less depth above the ceiling. Both models have the same baffle diameter (12") and use the same speaker grilles. Here's a pic of the 227C followed by its backcan - they're not small. I can only imagine how deep the 328 would have been!
I'm a little confused as to how to install these into my own ceiling - I think you have to drop the backcan in from the attic by cutting a 12" hole in the ceiling, which the flange rests behind. Then you screw the speaker into the backcan from the front. The rise from the flange is maybe 3/4" I believe, so if you have thick or multi-layer sheetrock, the baffle of the speaker will not be flush with the face of the ceiling, and then the grille - if used - won't be compatible.
This is all just cursory observation as JBL has not published any documentation on in-ceiling installation with the backcan. I asked about this in my own theater build thread and didn't get a response, but I'm still months away from any actual construction anyway.
