Just because a material is dense does not mean it doesn't flex! MDF flexes more than a GOOD grade of plywood. Plywood is stronger and lighter, especially Birch but the cost usually scare people away. I know of a major builder using OSB to biuld there high output boxes and trust me it doesn't flex like MDF. Polo..  |

Bronze Member Username: LexuscoopPost Number: 47 Registered: May-06 | eventually the wood will like bend and stay there from the air pressure... you can wait till then, but im sure you'll eventually ubgrade your system anyway... we all do LOL |

Gold Member Username: RzarectorCoquitlam, Bc Canada Post Number: 1187 Registered: Dec-04 | how can you say plywood doesnt flex like mdf? have you ever tried to bend a piece of mdf? its brittle and it will break because it is pressed glue and particals.. you can curve huge arcs with 1/4" plywood, if you try and do that with mdf itl snap.. yeah the higher end plywoods are very strong .. especially when they come with twice the ply .. but your standard 30 buck a sheet plywood isnt as good as mdf for rigity |

Silver Member Username: AdddisorderWest palm, Florida Post Number: 237 Registered: Jan-06 | well it is in a 3/4 plywood box and i dont think your going to be able to bend that and i dont think the assassin builds that much pressure to really flex it, but the problem i am having is the circle where the sub it mounted is like bump from peices of wood chipping off so air come out from around the sub, i tryed to cover it over with caulking when the sub was out but it didnt entierly fix the problem. so i was thinking about just making the ring out of MDF but i dont know if i should just build a entire new box out of just MDF, so what do you think? |

|
Silver Member Username: AdddisorderWest palm, Florida Post Number: 239 Registered: Jan-06 | yeah im going to, but my problem is that when i cut the circle out of plywood it chipped around the edges letting air get out. im going to build a new box however i dont know if i should use MDF for the entire box OR if i should use a MDF ring and then have the rest of the box 3/4 ply wood what would be the best choice |
