FG sound worse?

Yea, i have definitely noticed alot of douchey kinda people at the comps i go to. I just try and ignore it. What i love, is when some loser walks up when i'm about to run, and says "you know, you should get rid of those kickers". But, then i crush them,  So, next question. I know that this will probably be one of those "it just depends" kinda questions, but if i build this fiberglass enclosure (build it good), so that i can finally port these things (probably around 47hz) i'm hoping to gain at least 2DBs. Is this a realistic goal? I am told that CVRs really come alive in a ported enclosure (of proper airspace of course).

Also, i was wanting to make the ports changeable, so i can have 28 for daily, and 47 for comps. Anyone have any suggestions on the easiest way to do this.

Ports will definately make CVR's pound out some heavy dB's, just dont expect much for SQ.... of course I know those arn't gona be for SQ hehe. As for changable ports...... hummmmm..... the only way I could think that that would be possible to be to have 2 ports, 1 tuned to 28 and one tuned to 47 and have it where you can plug the cap from the inside (minimize distortion to the other port). I really cant think of a way that you could actually make physically changable ports."Shiny chrome when used in conjunction with bikini models is particularly effective in inducing brain deficit disorder"

Why couldnt you just have a port that bolted in and you could take the bolts out pop in the other port tube and put the bolts back in. Of course use a rubber seal around the flange of the port.Fortune: You will continue to take chances, and be glad you did.

A port's length cannot change without changing it's diameter also.  The longer port you have the wider in diameter it must be to accomodate the same tuning frequency.  The only possible idea (that I can make sense of) would be to create two ports, and just block the one not in use.

i have found that 2 things can make a huge diff in fg, 1) use some mdf for the large flat sufaces,it is best to make a small 't' on the flat sheet to brace the surface(obviously depending on the area of that sheet(like a 1*1,no biggie,but 2*1.5,run a 2" wide piece glued down the long way,to make a short 't')) 2) curve the fg as much as possible,cuves are always stronger,just like the sheet metal of the car,the edge of a curve on a panel doesnt flex,but the door panel does.. i guess one more thing,try putting expanding foam in the seams of like a wheel well,then shape it into a nice curve,then fg it.. think about a surfboard,itsjust styrofoamn with a thin layer of fg!just a little over 1/8 "..either one wouldnt do anything!,but together.. try some styrofoam instead of mdf if weight is an issue.. and you can,and should shape a brace like i said for the mdf into the foam.. if the 't' of mdf is too much,just use the 2" piece in the fg,with the EDGE of the mdf against the flat surface,it uses the same airspace,but is 10* stronger(probably more but..)PLEASE try some braces,you wont believe the diff!! a few small pieces mean the diff between being able to stand on the box,and being able to PARK your CAR on it..I mean park your car LITERALLY,i HAVE done it many times to show off the boxes i build..,and this is probably something many have thought of,but to find the volume,fill it with peanuts,and vacume them out.. for the anal customer,charge him more,and use sand,it cant change volume as much as sand..'Stereo' Mike
