[QUOTE="jacka, post: 1988138, member: 568366"] I'm trying to get an understanding of enclosures since my shop obviously doesn't know sh!t about the subject. Totally messed up the tuning Hz for my vented W3s. Well anyway. First off, I'm looking at recommendations and many say, for example, X.xx net cu ft. Now, if I wanted that exact about, I would have to add the driver displacement correct? and the MDF board doesn't play a role in that measurement, correct? Now on to vented boxes.. i'm lookin at soundsplinter recommendations and for the rl-p 12, they are saying 1.5 cu ft with 20 sq inch of vent area. i'm guessing that 20 sq in. means the visible port area from a 2D perspective, so a port of 1.6 inch wide and 12 inches will suffice for the requirement, am i correct? (my shop totally messed up on that part, and it shouldnt be that hard for them). Now tuning to certain frequencies is a bit hard to understand, how do I know how long to make the port? I guess that's all the questions I have right now. I'm looking to buy RL-p's next week and I don't really trust my shop to do me any good. I don't even know if they will make a sealed box to my preference. But yeah.. I'm just lookin for some info, I know a few people make boxes out there if you could quote me prices that'd be awesome. I don't really have the tools/room to build a box. Thanks. [/QUOTE]
