It's a simple matter of a sub should not be used with any other space then what is recommended. Why would you buy a sub and then not use the space they say you should use? Space is free...

As far as the OSB, there's no point to even bothering with it. I'm all about DIY and price per performance with car mods... but OSB isnt much cheaper then MDF and isn't remotely designed for this applicaction.

 

^agreed

there are subs that are designed to run in very small enclosures. here are the specs of the 8" subs I will be running. I prefer SQL, not SPL.

well some guy gave me the subs im not even sure what brand they are, im going to replace them when i get some money. but their in a large box right now and sound pretty nice

 

Use it as a mold or something to make a nice solid FG box. Might as well do something productive with it. Even though that would probably sound like poop, you didn't end up wasting good MDF. Now that you have some experience...make a good one with the proper materials...

Experience is what you gain from failure...though I wouldn't call this a failure.

 

yeah, im going to use them mainly for measurements cause i liked how they fit. oh and i forgot to post a 2nd pic of the amp. a little door actually slides open to show the settings and fan

 

Box size and shape effects sound. If you go out of tollerances, too small will cause tears in the surround or other parts of the speaker because the air is compressed inside the box too much.

Too much airspace can cause distortion or damage from the speaker moving too much


Less airspace will cause higher pitched sound, more will cause lower pitched sound. You can gain alot out of the shape of a box too.
