August 29, 200916 yr I'm thinkin the pressure levels are going to seriously hurt lol, and i'm looking foward to this design
August 29, 200916 yr hmm... what did i just come up with???I dont know?!?!Is it possible that i was just able to produce a port area of 550sqin? Nah i couldnt have..... could i? Mouth dropping port area for comp use? hmm...What about daily? Well, that's easy... you physically can't listen to it at that level due to the way our ears perceive sound at incredible pressure levels...330sqin of port sound like enough for daily? I believe it's doable!that is 12sqin per cube which is fine for daily, Eager for the results? How did i do it?!?!?!I'll show it all to you once the design has been laid out in great detail.

This build is gonna be hard probably so i wont want to do it in my car lol, and its more then i would ever attempt to put in my car lol.
August 29, 200916 yr got over 70% of the box designedAfter i get it all designed, i will post it up.then i will take another day or 2 to put the finishing touches on it.I'll go ahead and tell u guys that the pic i'll be postin up soon will NOT show the subs or port... just the box design.The subs, port and bracing is an artistic part of the design and takes time.

Thats awesome!
August 29, 200916 yr you'll get to see the BOX, nothing else, but just that is pretty nice enough for the time being while i get more precise numbers...
August 29, 200916 yr Boxie Box before details have been added-Now workin on details...Stay tuned throughout the weekend...
August 29, 200916 yr Boxie Box before details have been added-Now workin on details...Stay tuned throughout the weekend...That is looking beautiful lol, great job so far!
August 29, 200916 yr yes, of course pay no attention to all the breaks in the wood and pay no attention to exactly how all adjacent pieces join together...It's easier to draw it like that because for those who actually build boxes, we can just look at the pic and know where to break a run of wood.. common sense, lol.I'm gonna try and build the subs and port right now so the only thing left is bracing...So dont go anywhere yet!

August 29, 200916 yr Competition\Daily use!The port will be double MDF on the top half, the bottom half will be single layered MDF with some pretty nifty bracing.The lower portion port is 333sqin- this is the DAILY port tuned to ~ 30hz.The top portion gets plugged and hwo it gets plugged is pretty neat too... there is a reason why the top is double sheeted... it's part of the plug bracing.The top portion of the port is 217.5 sqin.When the plug is removed, it will be tuned around 37hz with 550sqin of port! Massive!
August 29, 200916 yr OH DAMN!!! that is beautiful lol, we're going to have to start building next weekend lol. You're being a huge help, i would have hated to design all of this lol.

Massive!Are we going to make the plug out of mdf, then just put it in place and secure it in for daily, so it will literally be like a cork.
August 29, 200916 yr yep, that's how a plug works.Lucky for you, daily is more forgiving than pure competition is.I would not suggest sealing the plug as it's unnecessary and pointless.Even if there was any air leaks through the plug, the pressure output for daily would have an inaudible difference.You want it so that it can be easily removable. There are plenty of ways to do this without hassle. Those are little things. I'll start working on bracing tomorrow.
August 29, 200916 yr Author I come home to find literally 23 new notifications for this topic. I ponder for a moment and wonder .... What would cause such a drastic amount of posting? Could it be that Shawn not only posted prints but found an incredible way to get competition porting out of the box? YES!!!!! ... This thing looks awsome! I am pumped to start this. It is looking absolutely incredible. Thank you so much for all your help on this design Shawn. Without you this would have never been possible.

August 29, 200916 yr Author My main concern is would it be possible for a small child to be sucked into such a massive port if I were to reverse the phase on these subs?Seriously though how wide is that port on the bottom lmao!!!
