Often times fiberglass is used in cars because of awkward shapes and sizes. Fiberglass is a rather resonant material this coupled with the fact that in home audio size restrictions are often not as odd it is far more efficient to use various forms of wood for speaker building.Ive seen a lot of custom fiberglass car boxes and was wondering why no one has done this with home audio to make one of those no baffle speaker enclosures
Car application fiberglass which the OP refers to is the latter of the two you described.are you talking about the clear fiberglass (like that of a basketball court) or fiberglass that can be molded into any shape?
I would look into using 5-6 layers of peel-n-seal/dynamat on the inside along with a material such as asphalt that has a strong ability to convert energy to heat. This would substantially reduce resonance. This would still not remove resonance, but I guess some is better than nothing - wood is still the best choice for home audio.I'd want to use some heavy damping material (lead/bitumen) and a lot of bracing in a fiberglass enclosure.
I think you are referring to bandpass enclosures. I guess it does depend, since this was a question in the diy speaker forum I thought he was referring to fiberglass enclosures that are seen in many custom installations in the car audio world. I guess only the OP can tell us.actually, most of the car sub enclosures here are wood and clear fiberglass combos ... to show some lights and drivers
i see, guess you are talking about the custom made one ...No offence but I think Mike c is confused floor wax and plexiglass are not fiber glass
thanks, it clears it up nowMaybe I can help and confuse you some more:
Fibreglass is a glass fibre matt/weave that is soaked in a polyester, vinylester or epoxy resin that hardens to create what is called a composite. This is used on surfboards, boats, planes and custom boxes/dashboards etc.
The wet stuff that is rolled over broken limbs is basically a bandage impregnated with plaster. It is basically plaster of paris.
the clear sheets of plastic is an acrylic based product that is called plexi-glass or perspex. It comes in sheets of various thickness and can be heated and bent.
