The 13 ply Baltic birch is outstanding,weighs a good deal more than the 7 ply Birch. via
Is fiberglass better than MDF?
You could easily fabricate two identical structures with the exact amount of fiberglass with different resonances, mdf should however be a lot more consistent of course per unit shape/size. Both are fairly easy to measure though--if you want comparisons, send me some to measure and I will do it for you. via

Can a sealed sub box be too big?
Sealed boxes will generally losen the air pressure inside, thus slowing down the woofer, thus reproducing a lower frequency. However after a certain point, it will become sloppy uncontrolled, and sound like trash. It all depends what your drivers specs are. via
Should I put polyfill in a ported box?

We spent right around $25, though your costs will vary depending on what you already have in the garage. via
Is bigger sub box better?
By making the enclosure a bit bigger it will become more efficient in many cases, increasing output. Remember, there is such a thing as too big. As the size of the enclosure increases, the mechanical limits of the woofer will be easier to reach. If the box is too small (by a reasonable amount) add power. via
Can you fiberglass over cardboard?
it will work. i went to michaels and got some cardboard 'bins' with caps on them and resin'd them for a test setup once. you could also use tuppawear or something like that. if its gotta be a specific shape, then cardboard would be fine because you can cuttape it together for a crude enclosure. via

What kind of fabric is used for a subwoofer box?
We recommend MDF (medium density fiberboard) or Medite (high density fiberboard), They are rigid, heavy and not porous like some particle boards. We recommend 3/4" (19mm) MDF although 1/2" (12.5mm) MDF is acceptable for woofers 8" and smaller. via
How much air space does a 10 inch sub need?
For a 10-inch woofer, the volume recommendation is 0.625 cubic feet, and the recommendation for an eight-inch speaker is 0.375 cubic feet. You can build a larger enclosure to allow for more volume of space inside to produce a flatter sound, which is better for music that is less bass-heavy. via
How do I make my subs hit harder?
You can also make minor upgrades to your subwoofer to make it hit harder. Change the small cone in front of the subwoofer, change the voice coil or get a new enclosure for the subwoofer. If you don't want to put much effort into it, just turn the volume to zero and play your track with medium bass. via
Is a sealed sub box better?
Sealed enclosures reproduce the low frequencies more accurately than ported enclosures because the air inside the box acts like a shock absorber, allowing the subwoofer to move back and forth in more control. via
What's the best wood to build a speaker box out of?
Our team of experts has chosen the Baltic Birch Plywood as the best wood for speaker box due to its high sound quality, density, rigidity, and durability. A subwoofer box building made with this wood produces the best sound quality with minimal tone distortions, resulting in more exact rhythms. via
What is marine grade plywood?
Marine Grade Plywood is an exterior structural panel, sanded on both sides, most commonly made from Douglas fir or Pine. Other species of hardwood may also be used for marine plywood, usually in the Marine (boating) industry. via

Can I port a sealed sub box?
You can place a port in your now sealed box. A simple hole saw and drill will do the trick nicely. Youll have to determine the net cubic air space. (net= space left after the subwofer is in) Then determine what tune frequency you want to port the subwoofer at. via
