What is the purpose of a transmission line enclosure?
Instead of reverberating in a fairly simple damped enclosure, sound from the back of the bass speaker is directed into a long (generally folded) damped pathway within the speaker enclosure, which allows far greater control and use of speaker energy and the resulting sound.
What type of subwoofer box is best?
MDF wood is ideal for making subwoofer enclosures. The wood is strong, durable, and thick enough to limit distortion of sound waves. A close second is a plywood, which is lighter than MDF, but sturdy enough to create the best sound-quality if laminated.
Are bandpass boxes better than ported?
1) Larger bandpass enclosures will have a smoother and deeper frequency response than a smaller bandpass enclosure but not as smooth as sealed or ported enclosures. This means that some frequencies will be much louder than others. Typically, one frequency gets very loud as compared to others.
What do you line speaker boxes with?
It is recommended that you loosely fill the speaker enclosure with polyfill and make sure it’s not blocking the ports, or line the walls with 1″ – 1.5″ acoustic foam. Your sealed midrange chamber should be heavily filled with polyfill, fiberglass insulation, or denim insulation.
Is vented the same as ported?
vented and ported are the same thing. if you mean slot-vented then say as much. even then, slot-vented and round ports serve the same mechanical purpose. It’s just a matter of box design, tuning frequency, etc.
What is a 4th order box?
A fourth order enclosure (vented box) is a sealed enclosure with the additon of a port tuned to a specific frequency. The port extends the low frequency response of the basic sealed enclosure usually providing a lower cut-off frequency.
Which is louder bandpass or ported?
a bandpass box will usually be more efficient and thus louder than ported or sealed. However, bandpass don’t play as deeply as they are usually tuned around 45-70Hz which may be loud but pretty much louds lousy doing it. If all you want is loud though, look at a 4th or 6th order bandpass box.
