SPK-CCF848 - Overview 3

3 Overview

The SPK-CCF848 ESD™ (Equal Sound Dispersion) Ceiling Speaker is a high-

performance complete K-overage ESD ceiling speaker that can be mounted on the

ceiling and appears as a suspended ceiling tile.

The SPK-CCF848 is constructed with a central driver and four pivoting tweeters

and is housed in an enclosed shallow enclosure.

The Kramer complete K-overage ESD provides unmatched sound response in a

suspended ceiling device for the professional (PRO) and educational (EDU)

markets. This means that you get the sound you need but with a reduced number

of speakers.

The SPK-CCF848 speaker features:

• Complete K-overage ESD™ – a patent pending design with 4 pivoting

tweeters that direct the sound, based on the room environment, for equal

sound dispersion (ESD)

• Wide 180° sound dispersion

• One Kramer ESD speaker that replaces multiple standard speakers for quick

and easy installation

• Excellent bass response that is optimized for music and high−quality voice

reproduction

• 4 pivoting tweeters, 3/4” (6Ω) with silk domes

• A polypropylene cone woofer (8Ω)

• A 40W RMS power rating

• Smooth frequency response

• A shallow 4-inch depth (approx. 100mm)

• RoHS compliance

Compliance to RoHS means acting in full accordance with RoHS regulations that
restrict the use of certain dangerous substances commonly used in electronic and
electronic equipment

4 SPK-CCF848 - Overview

• A choice of models: full tile or half-tile size, stereo or mono (see table below)

• A bass port for a bass reflex effect (for educational models)
