OK here goes...

DSP 1804 R/L
- or -
LRF 1804 R/L

DSP or LFR for the aforementioned reasons.

Now for the numbering sequence;
1 (extra driver) up front
80 rest of the array up front looks like an M80
4 (number of drivers in back)

L/R - should be obvious


A smaller version (if there will be one based on the M60 that I queried earlier would come out as:

LFR 1602

I (personally) think there needs to be additional number(s) to set them apart from the front-drivers-only speakers.

As part of a HT package, building on the "Epic" name, could be the "Intrepid" series.

OK, back to the fuel injection....
