The calculations I came up with are 10.94 cu ft. with a 18" driver. However I didn't account for the dimensions of the horn which will be a little smaller than that.
Based on published specs, the pioneer's optimum reflex = Vas/1.44 = ~196.53L/6.9404 ft^3 net, tuned to Fs, so ideally would use measured specs and if wanting the full 800 W rating, then the vent = 10" dia. x ~15.83" and this cab sealed comes inaudibly close enough to theoretical max flat.

Steve, I say junk the JerBiL Idea and pick up another 515-16 and turn it into a 5.1. I know that those big horns are hard to move, especially since we're getting older and are going to move. But the 288's on the left and right with some 808's on the mid's and surround and you won't be unhappy.
Hmmmm...well I already have these two...altec 605 and 511/802d...rear channels?Originally Posted by LOUDER
They sound incredible but they are ugly imho....not that i care.
If I painted the big horns real nice Altec gray...they would love pretty good I think...but I keep wondering if inside the new home that from 80-600Hz...the big mid bass horns are overkill. I wouldn?t know unless I actually built them.
But I?m laughing because you called the highest powered JBL 18? loudspeaker a gerbil/jerbil?
for some reason i see the image briefly, then it goes away and is replaced by 1?2....anyone seen this?
