Gold Member Username: Extrmndor3Chicago, Ill Us Post Number: 1661 Registered: Feb-06 | it will be pretty good, well im gonna be honest with you if ur going slot ported the end of the port try to put some bondo and sand it, the sharp corners will make some anoying noises, it will affect some turbulences inside the box, if i were u i try to make a box like that but witout the slot ported and put some flared ports u can buy them at tcab.com plus u can get any color u want, and it will be better it will almost ilimate all the turbulance in side the woofer(if u know how to place the port) and it will eliminate anoying sounds, u will have to internally brace it to help all the moving air and pressure u will have to go double mdf on the front side were u will place the woofer u will need to buy 3/4 mdf but like i said in front side try to put a double 3/4mdf to make it around 1.45 inch thick for better sound quiality and ge the most db's |

Silver Member Username: Crayola0Wisconsin Post Number: 537 Registered: Jun-06 | would flared ports be easier? |
|
Gold Member Username: Extrmndor3Chicago, Ill Us Post Number: 1664 Registered: Feb-06 | yeah sometimes flared port are easier if u use the right equipment, u can use a program but i forgot where it is i think its on carstereos.com to find the port lengh and port tuning yeah flared ports are better than slot ported makes good for better sound quility eliminate all the anoying sound or portnoise, plus u just have to cut a hole and place the port andput some liquid nails to make the ports tight well most of the high spl boxes have flared ports the car uaio box tcab.com only uses flared ports and they make some good thumpin boxes |
