The best way to cut carpet or vinyl is with a good quality carpet knife. It is not necessary to sand the subwoofer enclosure or subwoofer box if you are using carpet or padding under vinyl, since the thickness of the material will cover any small imperfections. If you are painting the subwoofer box, It is a good idea to apply primer under the paint. Play around with different amounts of polyfill until you get the desired results.įinishing subwoofer boxes and subwoofer enclosuresĪdd wood filler to holes and sand the box to make a smooth surface. Polyfill also "fools" a sub into thinking it is in a bigger box. This increases subwoofer efficiency by dissipating some energy that affects the sub, particularly the voice coil. Pillow polyfill and fiberglass insulation are common, though polyfill is a lot easier on your skin. It is advisable to put damping material inside a subwoofer box. inside a box take up space and should be accounted for when calculating internal volume. Always consider that blocks, braces, neon lights, etc. It is a good idea to put wood blocks on the corners for reinforcement. Bracingīoxes that are more than a foot on width or length or height, should be braced (use a piece of wood maybe 3 or 4 inches wide across the box, so that the subwoofer box does not flex). Seal the gaps using plenty of Liquid Nails or similar product. A couple wood braces can be added for screwing the port to the subwoofer box.

Make sure the hole is as perfect as possible to minimize gaps between the box and the tube. Consider the volume the port takes up when calculating the subwoofer box volume.

PVC tubing is very rigid, comes in different diameters, and is easily found at any hardware store.Ĭut the tubing at the desired length. If a pre-made port is not available, the most common material is PVC tubing. building a subwoofer box with a divider in the middle will be much sturdier. This could cause problems and even damage the other sub. Pre-drill about 3/4" deep, so that screws do not split the wood at the edges, especially when working with particle board.Įven though it is not necessary to have two separate chambers for two subs, it is best to take this approach for two reasons: First, if one of the subwoofers dies, then the volume of the subwoofer box will be "twice" as big, as seen by the sub that is still working. Screw joints (use 2" - 2-1/2" screws) every four inches or so. The fumes of some products will eat up rubber and other materials subs are made of. Let glue cure for at least 24 hours before mounting the woofers. Any leaks will degrade the performance of your subwoofers, not to mention the annoying noise air makes when being pushed out of a small hole. Use glue at all joints (cheapest and most used product is Liquid Nails). If building a subwoofer box with Plexiglas, do not use anything less that 1/2 inch thick.Ī common material used to mold complex shaped subwoofer boxes is fiberglass, but it is a real pain to work with, and several layers need to be applied for a solid finish.

Most common building materials are 5/8" or thicker particle board or medium density fiberboard. Materials needed to build subwoofer boxes and subwoofer enclosuresĪ subwoofer box has to be very rigid. Subwoofer boxes and subwoofer enclosures can be built in any shape, but it is difficult to calculate volume for complex shapes. If a sub is installed in a subwoofer box larger or smaller than what is supposed to, it will sound bad and could be destroyed. Some subs can't be used in certain types of subwoofer boxes, and have very small tolerances for box volume errors. Check with manufacturer or dealer for appropriate subwoofer box volume and design.
