If you give me a hug I might do it. I don't think the access panel uses T-nuts, so I'd like to keep the number of times I take that sucker off down to a minimum so the wood doesn't get torn to bits I'm curious too, so I might just suck it up, rip it apart and look. I know what's in there, but i have no idea what the driver inside looks like.... it's one of those mysterious 'no name CV' drivers whose specs elude everyone. ------------- http://bitcore.org/stuff/Bass_Tones/ - Bass Tones & Sweeps in 160kbit MP3 http://youtube.com/watch?v=mC9XqmyKaOY - I<3bass

well I've got a surprise for you.      What's going on below: Behind the driver, the baffle board's double thickness apparently does not extend all of the way back, as you can see. This is a picture at the back of the internal chamber, behind the driver, looking up.  Something interesting:  The cabinet *IS* the same cabinet for the Earthquake, the EL-36, so I'm not surprised. The only difference between the AB-36 and the EL-36 is the driver, the label on the back, and the front "heat sink" access panel. crap diagram I made real quick, measurements are good. Note: Any measurement that go from or to one of the main outside panels, is measuring the *inside* of the main panel, IE: from bottom to the back corner of the chamber is measuring from INSIDE the horn, not taking into account the thickness of the outside wood. The baffle's length is measured from the outside front edge to the back inside edge. the measurements 26 1/2" and 20 1/4" are for the dotted lines, measuring the OUTSIDE corners of the mouth joints. It's not to scale, duh, but the numbers should be good. There is about 1" between the top left corner of the enclosure and where the mouth meets the outer panel at the top,  I suppose people really want pictures of the throat, where we can't see, behind the driver. I'll get to that later as I didn't have pliers or my sockets handy. There are studs that extend from the other side of the baffle through where the driver is just bolted to the studs. bigified pictures here: http://www.bitcore.org/stuff/bass/Cerwin_Vega/Disassembly/big/ - http://www.bitcore.org/stuff/bass/Cerwin_Vega/Disassembly/big/ eidt: forum does not like the ampersand (&) in image url's ------------- http://bitcore.org/stuff/Bass_Tones/ - Bass Tones & Sweeps in 160kbit MP3 http://youtube.com/watch?v=mC9XqmyKaOY - I<3bass

Yeeeaaah, if that's the EL/AB, then screw measuring the rest of it! I knew someone out there has taken better measurements than I have. I'm going to mirror that. http://www.bitcore.org/stuff/bass/Cerwin_Vega/schematic.png - http://www.bitcore.org/stuff/bass/Cerwin_Vega/schematic.png My handwriting is actually pretty embarrassing anyways, so I'll probably delete that sometime soon. Yes, the AB driver is, well, kinda crap, I think... It's better than the one in the EL, (IMHO, I've previewed all 3 CV bins back to back before) and it takes some more power than the EL... However, even though the cone is really flexible, it's pretty stable in terms of wobbling off axis compared to any rubber/foam surround driver I've messed with - but it is a PA driver. Exams are coming up, I'm done on may 2nd, so if I have time later, I will measure the driver, unmount, and take a few more pictures.. Oh, if anyone in the US, near me, wants to buy this thing off me (local pick up only please!), get in touch with me. I can't really use this thing anymore, it's being stored at my father's house. I'm not trying to turn this into a sell thread! & please excuse my hijack! but I'm not sure where else I should list ONE used CV AB-36. Most everyone here is in Europe or overseas anyways. (first time I took the access panel off, & there's no damage, scuffs, or spilled beer on it either.) Please no more discussion about buying it, I don't want to troll. PM me instead. ------------- http://bitcore.org/stuff/Bass_Tones/ - Bass Tones & Sweeps in 160kbit MP3 http://youtube.com/watch?v=mC9XqmyKaOY - I<3bass
