What is 4K & 8K?

4k HDTV Facts:

• 4K HDTV provides four times (4X) the picture resolution of a regular HD (High Definition) TV.
• The horizontal picture resolution of a 4K TV is approximately 4,000 pixels
• 4K is already playing at a theater near you, but you probably didn’t even notice – DigitalTrends.com
• The equation is simple more pixels = more picture details

Whether it is a television, a tablet, or a smartphone, more pixels mean more detailed picture. The main concept is a screen where the pixel is invisible to the naked eye. A good example is Apple’s “Retina” display or the Curved 4K Ultra High Definition models — the best way to experience 4K is to stand right in front of  a 4K HDTV to look for any pixels at all. Because the picture is so sharp and clear, you can have a seat closer to an 4K HDTV to add even more of an immersive effect.

What distance is recommended  from the human eye and a 4K TV screen? Most scientists say sitting 1 to 1 and 1/2 times the total screen height, versus 3x times the screen height for a 1080p HDTV. That is closer than most people normally sit to watch HDTV however doing so really transforms the experience to a vivid adventure — All the screen surface completely fills your field of vision, making you feel like you are in the scene. Add to this appropriate room lighting and a Dolby surround sound system to un-mistakenly intensify this feeling of immersion.

Content or Compatibility Problems Again with 4k HDTV?

All 4K HDTVs come with built-in features such as 4K upconversion/scaling which takes the video signals and fills the 4-times greater pixel count of the 4K screen thanks to processing enhancements that make a 4K HUTV completely compatible with all your existent video components. If upconversion would not exist, a 1080p Blu-ray signal would appear as a small rectangular image at the center of the screen, with black bars on all sides.

4K TVs with Big Screens?

1080p resolution looks fine on screens 50″ or less because from a typical viewing distance you won’t notice the screen’s grid of pixels. But a 55″ or  larger screens benefit from a much higher pixel count, making the pixel grid virtually invisible. 4K HDTVs not only offers a more detailed picture, but also allows you to sit closer to a screen and/or view a larger screen while enjoying unprecedented clarity.

4K with Full LED Backlighting – See to Believe It!

After LG launched the world’s first 4K Ultra HD TV late in 2012. Now their first 2nd-generation 4K HDTVs are here, with even better picture quality than the one from 4k HDTVs. In addition to 4K pixel power, these 4K TVs use backlighting called NANO Full LED full-array backlight with local dimming.

8k HDTV Facts:

• 8K HDTV provides four times (4x) the picture resolution of a 4K HDTV.
• The horizontal picture resolution of a 8K TV is approximately 8,000 pixels
• The equation gets simpler more pixels the better picture details shown on the screen
• Futuristic Resolution – TechRadar.com

Do All Those Extra Pixels Matter in a 8k HDTV?

Short and simple, absolutely, yes! HDTVs gave you two mega pixel image (2MP) now imaging how  a 33 MP image looks like.  33,177,600 pixels to be exact!

8K Content?

Think about this: Tokyo olympics will be broadcasted in 8K HDTV thats only 3 years away from now (2017) Also, VR (Virtual Reality) already uses 8K resolution.

A New 4K and 8K Era

The era of 4K Ultra High Definition is already here to stay, look online for a tv mounting service near me and get your 4K or 8K HDTV mounted on the wall. Then just sit on your favorite recliner, stretch your legs, turn on your sound system to set the right mood grab the popcorn and enjoy movies and visual content like never before thanks to advances in technology. 8K HDTV is completely inevitable – it is already here!

Understanding Speaker Parts

It is very important to understand the parts of a speaker since it helps to demonstrate how speaker specifications compare to each other.  A complete understanding of how a speaker is built internally provides enhanced knowledge that can be visualized to depict what difference count on different type of speakers for the space.

Basic Speaker Parts

The Driver

A loudspeaker is defined as the sound driver or driver.  The driver is the main element of the speaker system since it converts line level voltage from your speaker amplifier into sound by pushing and pulling air molecules in waves that the human ear interests as sound.  A driver can be made from different materials — from the reinforced paper cone shape, a metal dome diaphragm or a carbon fiber element; all within a metal coil.

The Enclosure

Made from wood, plastic and in some cases drywall or concrete, the enclosure is the box or cavity where the driver is mounted. The enclosure can contain one driver or several drivers.
No speaker can exist without an enclosure.  The dimensions of the enclosure determines the volume of air movement, Therefore, the sound force a speaker can create in a given room.  This correlation states that the the size of a speaker enclosure should be related to the size of the room.  A loudspeaker engineered for a bigger room will unfortunately not sound as good in a smaller room. And correlatively, the same holds true for the other way round.

Speaker enclosures come several designs such as ported reflex that have a hole in the front or back to leak more bass.  Fascinating enough, some others are completely sealed — well designed sealed enclosures tend to produce more accurate sound.

Well-made speaker enclosures use structures that have been reenforced and mostly referred to in speaker specs as a braced enclosure — to reassure that the enclosure vibrate as little as possible to avoid undesirable coloration to sound especially at the resonant frequency of the enclosure which tends to be closer to the upper bass frequencies.

The Diaphragm:

The diaphragm is the device that convert mechanical motion into sound waves.

The Cone:

The cone is a diaphragm which is attached to the voice coil.  The cone is the part that contains a bigger surface and is designed for maximum air movement when the voice coil moves.  The body of the cone can be made from paper, carbon fiber, black polypropolene, aluminum, titanium, phenolic, magnesium, granite, fiberglass, ceramic or kevlar.

The Voice Coil:

Made from copper wire, the voice coil is an electromagnet that provides the motive force to the cone by the reaction of a magnetic field to the current passing through it.  The voice coil is a set of windings wound around an aluminum, nomex, kapton or other material form.  It is made using flat or round wound wire. Nominal impedances are 2, 4, 6, 8, 10, 16 or 32 ohms.

The Dust Cap:

The dust cap is a diaphragm designed to cover the voice coil opening other internal parts of the speaker.  It can be made of paper, aluminum, felt, rubber, screen, or polypropolene.

The Spider:

Made from treated paper coated with adhesive glue, the spider is located internally inside the speaker and its main function is to preserve the voice coil aligned properly and to reassure that the speaker comes back to its normal position between vibrations.  Its like a safety mechanism that ensures all interior parts stay in place. The Spider snuggly fits around the voice coil and is attached to the speaker basket.

The Surround:

The surround is the poly-foam, foam, butyl, accordion or a single cloth or “m” roll cloth ring that holds the cone and the basket together.  It acts as a suspension system that works harmonically with the spider to bring the cone to its normal position between vibrations.

Driver Diaphragm:

The driver diaphragm is attached to the metal basket via an acoustic spider suspension at one end and a flexible surround at the other.

The Basket:

The basket is the structure made from aluminum or plastic that protects all the interior parts and serves as and structural reenforcement so no additional distortions can be created.

The Gasket:

Made from foam, rubber or chip cardboard. The main function of the gasket is to minimize vibration between the driver and the enclosure.

The Magnet:

The magnet is made of a group of metals called the ferromagnetic metals.  These are metals like iron and nikel. These metals have the special property of being capable to be magnetized.  On a speaker the magnet is a big mass located on the back of the speaker.  The magnet serves as an negative or positive inverter for the the voice coil which in returns makes the diaphragms move and make the driver make a sound.

The Assembly:

The diaphragm, spider and surround are firmly attached to a voice coil suspended by a magnetic field created by permanent magnet.  The entire assembly is free to move in accordance with the movement created by the voice coil in response to the electric signal.  This movement moves air in the room to create sound.

Speaker Design

It is very important to understand speaker parts by the way the are designed since it helps to demonstrate how speaker specifications compare to each other.  A complete understanding of how a speaker is built internally provides enhanced knowledge that can be visualized to depict what difference count on different type of speakers for the space.
