Small ported enclosure for RSDC 12

Hey folks my first post here. Planning a system in my A4 wagon based around all of the PG RSD line. But I have a few questions regarding subs. Originally I planned for a pair of RSDC 12's in a 2.3 cu.ft. enclosure which fits fine. However, I re-arranged a few things and looks like I can fit nearly a 4 cu. ft. (before displacement)enclosure. My question is I know PG recommends 2.5 cu. ft/sub vented for SQ. I'm looking for more of an SQL type enclosure. What do you guys think of ~1.75 cu.ft. net vol./sub tuned to 34-38 hz. ? Will the lower enclosure volume kill my bottem end?
Opinions? Thanks!

http://www.youtube.com/watch?v=D7pUwlg2d14 itll give u an idea what a RSdC12 will do in a 2.3 cuft (before sub) with a port tuned around 27-29hz powered by a Ti600.2 bridged @ 8 ohms (300 watts rms) will do hope this helps. also I took the rubber boot off the magnet and used a polylining in the box heres my install link

Hey thanks knightrider! Awesome video and install. Sounds really good to. From the looks of it you're probably right around 2 cu.ft after sub and port displacement and the bottom end didn't suffer. Looks like your tuned fairly low as well. I think I may just go with the 4 cu. ft. box tuned around 29-32Hz. Ports are gonna be fairly long but I think I can get away with it. I'm gonna be running two RSDC122's on a RSD1200.1 @ 2ohms so I hope have enough power.
