I'm surprised packing space isn't important to you - most people buying active subs like these want to move them around.

If it isn't, then you're right I'd say, for your purposes you have to decide whether per-box lifting weight or sound quality is more important.

You might want to consider something similar to the PRX from another manufacturer that meets your lifting weight requirements better - I'm sure there are other good active 18" subs around that have neo drivers.

His answer was consistent with my prior understanding of what happens to subwoofer drivers and cabinets as they get driven near their limits. Extension and response also tends to even-out with sub groupings due to the way multiple similarly-sized cabinets give you essentially twice the LxWxH volume if you go 2X the number. There have been tests that show it.

Reflex designs (like the cabinets we're discussing) don't get much if any low frequency extension from coupling, as I understand it. Horn designs on the other hand very much do, as the frequency to which they play is dependent on mouth size. In other words, you will always get more bottom end from the PRX.

My knowledge is limited as to whether the response flattening will happen with coupled reflex cabs - I know this is the case for horns but I'm not sure about reflex.

EON supposedly has a more-wimpy & inferior woofer design, but like anything in audio I would expect trade-offs in voice coil size to possibly have benefits elsewhere. Is that wrong?

My gut feeling is that the EON's will be very much engineered down to a price point, and the quality of the drivers in them will reflect that. It may be the case that they have a lighter driver and a slightly better transient response but I wouldn't bet on it.
