INSTALLATION RECOMMENDATION FOR OPTIMUM PERFORMANCE

Important Note : Vanishing Series Loudspeakers are not magnetically shielded and should not be placed closer than 1’ (30cm) from a CRT (tube) television or video monitor.

Important Note:
You should have a thorough understanding of and adhere to all local building and fire codes. Also, you should be familiar with the area behind the wall or ceiling into which you plan to install your speakers. Always use wire that meets appropriate building and fire codes. (Note: Wiring is best performed by an experienced professional.) When installing your loudspeakers, be aware of the weight of your particular model and the sturdiness of the material into which you are installing the speaker. Be aware of any concealed studs, electrical wiring or plumbing in the wall or ceiling into which you are installing the speakers. If you doubt that you possess the necessary skills or tools, consult your Polk Audio dealer or a professional installer.

LOUDSPEAKER INSTALLATION

You will need:Polk Audio 625RT 2-way In-wall Speakers
\(1\)

  • Pencil for marking the location of installation.
  • Keyhole saw, utility knife or material- appropriate tool for cutting drywall or other wall material.
  • Level.
  • Screwdriver, preferably powered, with Phillips Head bit.
  • Power drill with appropriate bit (optional, for starting wall cut).

IMPORTANT INFORMATION BEFORE YOU INSTALL YOUR LOUDPSPEAKER

Wall Or Ceiling Surface Preparation
If you’re installing your Vanishing Series speaker into a heavily textured wall or ceiling (e.g. stucco or popcorn finish), you must prepare the wall surface immediately around the speaker  cutout. Sanding and smoothing the wall or ceiling surface will ensure the speaker and grille both seat properly and flat to the surface.

IMPORTANT INFORMATION SHOULD YOU CHOOSE TO PAINT YOUR GRILLES
Because of its ultra-thin profile, the Vanishing Series Sheer-Grille™ requires a specific painting procedure to ensure smooth, even coverage. The grille scrim and perforated grille come assembled and require no disassembly.

Paint Recommendation
We highly recommend you use a can of spray paint matched to the wall color you want the Sheer-Grilles to blend with.

Important Note: Never use a brush or roller to paint the grilles, as this will clog the perf holes.

To paint the Sheer-Grille

  1. Elevate the Sheer-Grille off of a flat surface. This will ensure even coverage of the grille frame and make it easier to pick up. Mounting Idea: Two spray can caps will raise the grille high enough.
  2. Hold the spray paint about 12″ from the grille and at a 45° angle.
  3. Apply one light, thin coat, moving evenly side to side over the grille, then work your way around the perimeter of the grille to ensure you cover the grille frame.
  4. After each application of paint, wait approximately 1 minute, rotate the grille 90°, and apply the next thin coat. Important Note: You must rotate the grille 90°. Use your hands to define the next 90° rotation and always rotate the grille in the same direction of travel.
  5. Three light, even applications should cover the grille and frame adequately. Remember to work your way around the grille frame to cover it evenly and completely.

SURROUND SPEAKER PLACEMENTPolk Audio 625RT 2-way In-wall Speakers
\(4\)
Polk Audio F/X® surround loudspeakers give you nearly endless placement options. But remember that where you place your surround speakers requires some careful thought, as installation requires that you cut a hole in your wall or ceiling.

Diagram shows speaker locations for 5.1 and 7.1 systems, when two additional in-wall speakers are installed in the rear wall.

Left/Right Orientation: F/X® surround loud- speakers have a left/right orientation, and each speaker is clearly marked on the serial number label on the back of the magnet for installation on either the right or left. Right and left are defined from your listening area as you face your system’s center channel.

Center Channel Speaker Placement
Install the 255C-LS or 255C-RT as close as possible to ear level. If the speaker needs to be installed higher, aim the tweeter down as required.

Do not block the center channel with your TV or furniture.

Please Note: For more on speaker placement go to: www.polkaudio.com/education/article.php?id=15 or www.polkaudio.com/downloads/hthandbook.pdf

ROOM ENVIRONMENT CONTROLS

Imaging (65F/X-LS model only)
F/X Surround Loudspeakers offer switchable “Diffuse” and “Solid” imaging patterns to create the surround effect you desire.
A “Diffuse” image is defined as one which creates a “cloud” of sound; think of the effect as ambient sounds which fill the environment all around you, but are less localizable.
A “Solid” image is one which creates a more pin-point sound; sound is more localized. The location of sounds in the sound field is more identifiable.

Tweeter Switch
(LS and RT models except F/X models)

Filter— If your listening room is very reflective, with smooth sheetrock walls, hardwood floors,  and non-cushioned furniture, the sound will be overly “bright” and unnatural. Selecting the “Filter” setting compensates for the effect of reflectivity in a hard room. Tweeter attenuation flattens room response, without hindering higher frequency response, for warmer, more realistic sound and more accurate imaging.

Norm— If your room is not reflective, with curtains, artwork, lots of cushioned furniture and carpeting, sound will be absorbed by the room, resulting in more realistic reproduction and more accurate imaging. In this case, select the tweeter “Norm” setting.

Wall Distance Switch

(65F/X-RT and all LS Models except the Center Channel)
In-wall loudspeakers excel when placed more than 2’ (60cm) from side walls. If position limitations demand that in-wall loudspeakers be installed closer than 2’ (60cm) from side walls or ceiling, the proximity of the surface can result in a response “bump” between 50 and 200Hz.  This can cause in-wall speakers to sound “boomy.” The “Wall Distance” switch flattens response and eliminates “boominess” without sacrificing deep bass response, for more lifelike sound.

WHEN TO USE THE PROVIDED PORT PLUG

Important Note: Use the provided port plug when you are installing any of the in-wall loudspeakers listed below in an area larger than a standard open stud bay. Ensure the plug seats all the way into the port.

The port plug should be used on the following models:Polk Audio 625RT
2-way In-wall Speakers \(9\) 265-LS, 65F/X-LS, 65-LS, 265-RT, 65F/X-RT & 65-RT.

FREQUENTLY ASKED QUESTIONS

What dimensions do the cutouts have?

12-3/4″ H x 7-1/4″ W or 323.90mm x 184.2mm

Is a 2-way speaker good?

The sound quality is frequently better if a signal is solely separated into high frequencies and low frequencies.

What is a 2-way speaker system?

The woofer and tweeter are two different types of drivers found in 2-way speakers.

Why do speakers have 2 inputs?

Dual-input terminals are provided by manufacturers so that customers may bi- wire their home theatre systems to increase audio fidelity and provide a more expansive aural environment.

Do I want 2 way or 4 way speakers?

It’s possible that a 2-way speaker will create sound of a far greater caliber than a 4-way speaker.

Do 2 way speakers have good bass?

Because they have a dedicated woofer, two-way speakers are effective for bass. The woofer handles the low frequency, but you can choose to add an extra subwoofer to enhance the low bass tones and enhance your listening experience.

Do 2 way speakers need an amp?

Even though it’s not really necessary, acquiring an amp for them is strongly advised. It might not only be about getting fantastic sound while you drive.

Do 2 way speakers need a crossover?

A crossover is necessary for 2 way, 3 way, and 4 way speakers. A Low Pass Filter or a crossover will be required if you install a subwoofer.

What is the difference between 2 way and coaxial speakers?

Coaxial speakers are often coupled in the manner of a woofer and a tweeter, whilst 2 way speakers are typically paired in the manner of a subwoofer 1 and a subwoofer 2 to provide the highest quality sound.

Do 3 way speakers have more bass?

Although they don’t create as much bass, they are simpler to install and generally function effectively. For more complex configurations and high-end audio systems, 3-way speakers are preferable.

Do you need a subwoofer with 2-way speakers?

Although a subwoofer is not necessary for speakers to work, it nearly always makes sense to add one to a set of speakers, particularly smaller bookshelf speakers.

Can a speaker be both input and output?

Speakers are output devices since they receive information from computers (consider cellphones, laptops, tablets, etc.).

Can you plug 2 speakers into one output?

The only actual options for connecting two speakers to a single amplifier are parallel and series connections. You can often connect speakers in parallel if they have an impedance of 8 ohms or higher.
