TeejayBee Posted August 7, 2011 Report Share Posted August 7, 2011 Google search said a 3/4 4x8 sheet of MDF weighs 96lbs, and same size for birch is 70lbs so 26 lbs Quote Link to comment Share on other sites More sharing options...
zx10intn Posted August 7, 2011 Report Share Posted August 7, 2011 (edited) how much lighter is a sheet of bitch vs mdf.. ive always wanted to know i have never weighed it, but i would guess a 4x8 birch sheet weighs about 70% as much as the same sheet of mdf edit: ^^^ damn, close for a guess Edited August 7, 2011 by zx10intn Quote 1969 Chevy Chevelle 20/22" staggered Bonspeed Huntingtons wrapped in Nitto INVO's Mechman 250amp cs144 alt w/AVBM Kinetik 1800 main battery/Kinetik 2400 in the trunk Pioneer AVH-3200dvd Headunit (2) sets of Hybrid Audio Technologies Imagine components up front (2) DD 3512's d4 coils Sundown sax100.4 component amp Sundown saz-3000d subwoofer amp 5ft^3 box tuned to 34hz MY BUILD Link to comment Share on other sites More sharing options...
David Posted August 7, 2011 Report Share Posted August 7, 2011 I like mdf. Its a lil heavier but much easier to work with in my opinion, doesn't splinter when cutting or routering, and as long as you brace properly you can have a ton of power and multiple subs..

Stee-Z Posted August 7, 2011 Author Report Share Posted August 7, 2011 =P i have my MDF box, ill make a birch one this winter in wood shop, and see watch one i prefer =P... the only downfalls i'm hating on the MDF right now is how easy it cracks, its like handling a little baby while getting hit by a car..... hard to work with!... well not necessarily hard to "work with" but you just have to be careful about drilling, screwing , and screwing in the screws a little to deep, it will also "crack then" Quote (4)DD 9918's (2)DC 10k 8 6.5" focals 2 DD SS4 mid amps Audison Bit One processor Jl-cl-rlc line driver iPad in dash Dual Irragi 320a alts 8 batcaps 4000's Second Skin sound deadened Link to comment Share on other sites More sharing options...
jmilch Posted August 7, 2011 Report Share Posted August 7, 2011 I am a oak ply guy myself... Strong as birch and IMO it looks better. It may be $15 more than MDF, but it smells good when its cut, and it is MUCH MUCH lighter than MDF.

94retta(219) Posted August 7, 2011 Report Share Posted August 7, 2011 With sound you actully want the panels to be heavier. Its a way to dampen the box. People are saying ply is stiffer. Well it is but it isnt if that makes sence.. Long storie short, birtch resonates more then mdf does. Mdf is better imo Quote BUILD LOG Link to comment Share on other sites More sharing options...
Stee-Z Posted August 7, 2011 Author Report Share Posted August 7, 2011 well i guess its pretty much taste from what i'm understanding.. idk i'll make another box and see what i prefer Quote (4)DD 9918's (2)DC 10k 8 6.5" focals 2 DD SS4 mid amps Audison Bit One processor Jl-cl-rlc line driver iPad in dash Dual Irragi 320a alts 8 batcaps 4000's Second Skin sound deadened Link to comment Share on other sites More sharing options...

kryptonite Posted August 7, 2011 Report Share Posted August 7, 2011 I've used mdf and birch, ill never go back to mdf again. Lighter, stronger, doesn't get destroyed when it gets wet, less dust, when u sand it won't gum up the paper. Def worth the money but before you buy it at a big chain store like lowes or home depot or wherever OS local, check the contractors lumber yards. They are usually cheaper and better quality.
