Agreed, I was hoping they would redo their xB1 underseat enclosure for the xB2, but apparently that was a no-go.
I'm likely going with the single 13.

 

I can't decide what to do. I'm going to finish installing my old amp/sub but I'm not thrilled with having a sub box clearly visible in the cargo area or the space that it takes up. I could spend $175 for a cargo area cover to hide my sub, $150 on a Kenwood KSC-SW1 and hide it under the seat or $175 for the eD box and $50 for another 10" driver.

 

Losing usable cargo space and having somehting visible are two no-no's for me, hence my leaning towards the eD enclosures, choice of amp is making me favor the 13".
What are the specs on your amp Fred?

 

I remember when I had this box in the trunk of my 626. It was fine 95% of the time but 5% of the time, I really needed the space it took up. I also remember having windows broken on 3 occasions to steal speaker boxes, amps and radar detectors.

My old Kenwood mono amp is only 120W rms/240W peak but is 2 ohm stable at 160/320W. It's not much power but it could probably drive an efficient pair of 10" 4 ohm subs.
