Our take on the Niles Cynema™ Soundfield CSF48P

Sound bar speakers: room-filling sound with less clutter

Add big sound to your TV without a roomful of speakers. Sound bars require minimal space and wiring, and their sleek designs complement today's flat-panel TVs. Most sound bars have their own built-in amplification, so you won't need to use a home theater receiver. Some models use advanced surround processing and carefully aimed speaker drivers to simulate the effects of a full home theater audio system.

Engaging home theater sound from a space-saving, in-wall speaker

The revolutionary Niles Cynema Soundfield in-wall sound bar system may just be the perfect combination of stealth and home theater performance. This three-channel speaker package installs flush under your wall-mounted flat-panel TV and connects to your home theater receiver, taking the place of the left-, center-, and right-channel speakers of a traditional surround sound system. You'll enjoy impressive levels of clear, detailed sound to accompany your favorite TV shows, movies, and video games. The speaker's magnetically attached, low-profile MicroPerf® grille can be painted to match the color of your walls for a nearly invisible look.

Modular design means no cutting or drilling of wall studs required

Niles' innovative in-wall mounting system allows the speaker to be perfectly centered under your flat-panel display without the need to cut or drill wall studs. The system includes three self-contained, sealed speaker modules that tuck down and into the wall between the studs, then snap into place on the Cynema Soundfield's mounting frame. Each module can be adjusted horizontally along the width of the frame to achieve optimum imaging and separation.

Features

Overview: The Niles Audio Cynema Soundfield System is the first in-wall soundbar that installs flush below your wall-mounted flat panel TV. The CSF48p is a passive system that includes three self-contained speaker modules (for left, center, and right channels). These speaker modules tuck down into the wall cavity between the studs, and can be adjusted along the mounting rails for best separation. The system comes with a flush-mount grille for a seamless look.

Speaker Modules: The three speaker modules are self-contained sealed enclosures with dual 2" x 3" oval woofers and a 1" silk dome tweeter. The curved rear wave enclosure tucks down into the wall, while the drivers fire out of a 9" x 3" frame on the front. Only 3-1/2" depth behind the drywall and 3" of clearance inside the wall below the cutout is required. The woofers are angled slightly upward toward the listening area. Gold-plated spring posts are mounted to the bottom of the enclosure to connect your in-wall speaker wire. Speaker module dimensions: 9-5/8" L x 4" D x 6-1/2" H.

Audio Performance: The speaker modules should be connected to the left, right, and center channel outputs from your A/V receiver. Each module has a nominal 6Ω impedance, and can handle up to 100 watts. Other speaker specifications include:

  • Frequency Response: 65Hz - 25 kHz
  • Sensitivity: 86dB, 1 kHz @ 1W/1m
  • Max SPL: 105dB (LCR system)

Grille: The CSF48p comes with a white metal MicroPerf grille that attaches magnetically to the in-wall mounting system's frame. The 48" x 5-1/4" grille is only a 1/4" thick to give an unobtrusive appearance. The grille is paintable to make it virtually disappear into the décor.

Installation: The Cynema Soundfield System is easy to install. The flexible and unique In-wall Mounting System lets you install the system without cutting or drilling into the wall studs. A cutout in the drywall of 45-1/4" W x 3-3/4" H is required. (A cardboard template is included to assist you in making the cutout.) Four screw-down brackets and two clamp-down end brackets are included to hold the top and bottom rails in place. The three speaker modules snap into place between the studs, with covers and joiners to fill in the gaps. The modules can be adjusted laterally along the rails for optimum imaging.

Wiring: Since the speaker terminals will be inside the wall cavity, in-wall speaker wire will be required. When running loudspeaker wire inside walls or ceilings, you should use special jacketed cable (CL-2 or CL-3 rating) to protect the wire and to meet fire prevention and building codes. Please consult your local building official for code compliance. The recommended wire gauge depends upon the length of wire required from the amplifier to the speaker:

Length of Wire
(Amplifier to Speaker)
Wire Gauge
Less than 80 feet 18 gauge
80 feet to 200 feet 16 gauge
More than 200 feet 14 gauge
