What is a MLTL speaker?

Basically, an MLTL is a quarter-wave transmission line enclosure with a port. King, Mass Loaded Transmission Line (MLTL) speakers are now relatively straight-forword to design for the DIY audio enthusiast.

How do transmission line speakers work?

Inside a transmission line (TL) loudspeaker is a (usually folded) pathway into which the sound is directed. The transmission line acts as an acoustic waveguide, and the padding both reduces reflection and resonance, and also slows the speed of sound within the cabinet to allow for better tuning.

How do you make a transmission line speaker?

Here is how to design the transmission line : Find the length of the transmission line by dividing that wavelength by 4 (the quarter wavelength). Make a path from the back of the speaker to the front of the speaker, which is exactly the length you just calculated. The path can take different shapes.

How long does it take to build a transmission line?

Timeline: On average it can take 10 years or more to build a high-voltage transmission line. This timeline includes planning, scoping, mapping, environmental review, public comment, project approval, permitting, land acquisition, and construction.

What is line array speaker?

A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. Loudspeakers can be designed to be arrayed horizontally without behaving as a horizontal line source.

What is isobaric subwoofer?

An isobaric subwoofer box design sounds like something that only an experienced engineer can grasp. Therefore, isobaric stands for “equal pressure” or “constant pressure“. The main idea of the design is that you have 2 identical speakers, and 1 small chamber between them.

Why are there 3 power lines?

Because they carry 3-phase alternating current. When there are just 3 cables, the circuit is closed by ground. When there are 6 cables, it is a double-circuit power line. When there is a 4th cable, that is the ground cable and it is above the others, to protect them from lightning.

How much power can a transmission line carry?

Transmission line voltages vary from 44,000 to over 765,000 volts. The higher the voltage, the more electricity the line can carry.

Are line array speakers good?

Vertical line arrays and column speakers tend to provide good control of the vertical coverage, but provide a predetermined horizontal. Unless designed with an eye toward the real beamwidth characteristics of each cabinet at each frequency, this can result in unexpected interference between the two loudspeakers.

What is array audio?

It is a series of loudspeakers that covers the same frequency range and is stacked above one another. The key to a line array is that the speakers face slightly different vertical angles, allowing them to consistently cover a greater depth of field than a single PA speaker can.

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 is an mltl?

Basically, an MLTL is a quarter-wave transmission line enclosure with a port. Now, some may argue that this is a bass reflex enclosure – and the line is indeed a bit blurry. However, rather than engaging in a lengthy discussion on naming conventions, I will use the term MLTL to describe a ported quarter-wave enclosure.

What is a transmission line speaker?

Quarter-wave transmission line speakers employ enclosures that are tuned to provide low-frequency extension for the speaker driver. There are several types of transmission line enclosures and one of the more popular ones is the mass loaded transmission line (MLTL).
