I went to look at some subs, and I saw the reg boxes with the subs in there, u know the reg wooden boxes, fine

then i saw the plastic boxes, where the sub is completely enclosed in the clear plastic box, in the plexi glass. Is the sound different in the plexiglass box?, better quality? quieter?

The walls will flex in a plexiglass box, and the response wont be as clean, especially at louder volumes. They look damn cool, but their performance is sub-par.

hes talkin about bandpass, and bandpass = pussy

He said the sub was completely enclosed in plexi. Bandpass boxes have tuned vents, so they arent completely enclosed.

1 inch plexi flexes?!?!?!

 

[pavell]

i don't really want that loud loud bass sound

i want more like the clean low sound
so would the plexi box be for me?

The problem with a plexi box, assuming that it is structurally sound, is that you can't insulate it. All boxes ideally are insulated either with dacron (pillow stuffing), or recaimed carpet padding. If you fill a see-through box, it won't look too good.

Why would a properly sized box need polyfill? Thats only needed if you have a box that is to small and need to make the sub "see" a larger enclosure. A properly sized or tuned box shouldn't need any polyfill. And the one thing you want to avoid is an absolutely square box---to avoid standing waves-----thats why you usually either want the plane that the subs are mounted on or the plane (side) opposite that sub to be at an angle to rid yourself of standing waves -----or if all else fails you can get deflex pads which will do the same thing if you have to have a square box. And yeah...plexi doesnt flex unless it is to thin....just as MDF will flex if it is to thin.

Even properly sized boxes need to be insulated. While having an angled adjacent rear wall does help conciderably, there is no substitute to insulation. If you have the time and skill to not only design a box out of plexi but also take the time to construct it in a way to help eliminate standing waves, then go for it. However, if your box is going to look like all the other plexi boxes out there -square or rectangle- your performance will suffer without insulating it. I brought up one trick that I use for plexi boxes a couple of months ago. I cut a piece of padding to the shape of the wall opposite the sub and carpet it a color that matches the box. Then glue it down. The difference is night and day.

IM NOT MAKING MY OWN PLEXI BOX

i saw a retail box, it had like glass covering or platic covering i dont know what it was

 

[FlipFlopBox]

i got a peice of plexi if anyone wants it lol i dont need it its 3/4" thick and its like 42x17???

Since your NOT making your own box, it probably DOES have an opposite wall parallel to the sub. Trying my suggestion will make a large difference, but not as much as proper insulation.

 

[enough_talkin]

i make boxes with a combination of mdf fiberglass and polycarbonate...plexiglass is shit...polycarbonate is strong though...3/4'' polycarbonate = bulletproof glass :machinegun: :cheesy: most of the polycarb i use is 1/4'' which is something like 25 times as strong as plexi and 250 times as strong as glass...it doesnt flex from what i know of it ... if its plexi forget it though...plexiglass is garbage

I wouldn't advise using plexiglass on a SQ or SPL box unless the box was for looks instead of performance. Reason? Because it flexes unless it is small peaces.
