CC65T White/CC65T Black 6.5˝ Commercial 70V 2-Way In-Ceiling Speakers

Introduction

The CC-T series 70-volt in-ceiling speakers are perfect for commercial applications where you want high-quality sound with the capability to reach loud volumes. These speakers are designed to handle music, PA announcements, chimes, and more. We combined high-quality home theater audio with 70-volt technology, delivering the best of both worlds. With selectable tap wattage from 2.5W to 20W, these speakers are versatile for any commercial setting.

These in-ceiling speakers are precision-tuned for optimal audio at both high and low volumes. For superior musical sound, a 2-way speaker is essential, with a dedicated tweeter for highs and a dedicated woofer for lows. The polypropylene woofer cones produce clear, rich mids and deep bass, while the Mylar dome tweeters provide clean, crisp highs. The included sheer grilles allow flush installation and can be painted to match any decor. High-quality spring-loaded push terminals ensure secure wiring.

 

Setting the Taps

The tap is the selector knob located at the rear of the CC-T Series speakers. It allows you to set the wattage that the built-in transformer will draw from the amplifier. CC-T Series speakers have taps set at 2.5, 5, 10, 15, and 20 watts for 70-volt input, providing full customization of the sound output based on the needs of each area. For example, in a restaurant setting, you might set dining room speakers at 5 watts, outdoor seating speakers at 10 watts, hallway speakers at 2.5 watts, and bathroom speakers at 5 watts.

A great advantage of 70-volt systems is that you can mix and match various speaker types, such as ceiling speakers (like these), wall-mounted speakers, subwoofers, and more.

Wiring

70-volt speaker setups allow you to run very long lengths of speaker wire without signal loss. Connect all positive terminals of the speakers to the positive 70-volt terminal on the amplifier. The negative terminals of the speakers should connect to the COM (negative) terminals on the amplifier. Impedance is not a concern in 70-volt systems, as the power remains constant.

Ensure that the total wattage of the speakers (number of speakers multiplied by the tap value) does not exceed the output power of your 70V amplifier. For example, with 5 speakers set at 20W each, you’ll need an amplifier with at least 100 watts (5 x 20 = 100W). It’s recommended to select an amplifier with 15-20% more power for optimal performance, so in this case, a 120W amplifier would be ideal.

Below this sits a secondary multi-zone terminal strip labeled 70V SPEAKER ZONES OUTPUT (ZONES 1 through 6).Positive Connection: A red wire runs from the 70V binding post up to the positive ($+$) terminals of five ceiling speakers.Negative Connection: A black wire runs from the COM binding post up to the negative ($-$) terminals of the five ceiling speakers.Speaker Array (Top):Five circular ceiling speakers shown angled side-by-side in a horizontal row.Parallel Wiring Layout: The red positive line connects to the positive ($+$) terminal of every speaker in series along the top. The black negative line connects to the negative ($-$) terminal of every speaker in series along the bottom, demonstrating a daisy-chained parallel circuit.

The black negative wire connects to the negative ($-$) terminal of the first speaker and continues to the negative ($-$) terminal of the second speaker.Impedance Summary (Right): Large text on the right side reads "4 Ohms at the terminal", reflecting the total parallel resistance load created by pairing the two 8-ohm speakers.

 

Installation

Tools Needed: 

  • Drywall Knife 
  • Level
  • Phillips-Head Screwdriver 
  • Wire Strippers
  • Ladder
1.) Using the included template, cut an opening in the drywall.

Always allow at least ½˝ between a wall stud and the speaker cutout or the locking tabs will not be able to swivel into place.

A technical installation schematic labeled with the number 1 in the top-left corner detailing the template preparation step: Leveling Tool: A bubble level tool is positioned horizontally across the top edge of a paper template sheet to ensure straight alignment. Cutout Template Details: Features a central circular dashed line labeled "TEMPLATE Cut-out and levelling template" with crosshair centerlines extending vertically and horizontally. Printed text along the four crosshair outer points reads "Attach plumb line to crosshair". The bottom of the paper sheet reads "1:1 SCALE". Tracing Action: A pencil on the left points toward the outer dashed circle, demonstrating tracing the circular pattern onto the mounting surface.
2.) To remove the grille use the included hook tool. Insert the bent end of the tool into one of the holes in the grill. Gently lift the grill out being careful not to bend it.

A technical installation line drawing labeled with the number 2 in the top-left corner detailing speaker grille removal: Speaker Housing: Shows a circular ceiling speaker lying flat, featuring a smooth outer bezel flange, a mounting clamp visible underneath, and a fine mesh protective grille covering the driver assembly. Removal Technique: A hand at the lower-right stabilizes the speaker rim, while a hand at the top-right uses a thin removal tool inserted under the outer edge of the mesh grille to detach it from the speaker bezel.

3.) Connect the speaker wires (be sure to observe proper polarity), set taps to the desired power setting (see diagram on the facing page), and insert the speaker into the cutout with the locking tabs facing inward (See inset).  
A technical installation line drawing labeled with the number 3 in the top-left corner, detailing the ceiling placement process: Main Diagram: Ceiling Opening: Displays a circular cutout opening in the ceiling with speaker wires hanging down through the center. Upward Insertion: Two thick upward-pointing arrows indicate pushing the body of the ceiling speaker assembly straight up into the prepared hole. Speaker Profile: Shows the exposed front speaker cone, central tweeter assembly, outer bezel flange, and rear mounting hardware. Inset Box (Bottom Right): Clamp Detail: A close-up view showing a mounting dog-leg clamp mechanism, with a curved directional arrow illustrating how the mounting ear rotates outward to grip the backside of the drywall ceiling.
4.) Use a Phillips-Head Screwdriver to turn each screw clockwise. This will cause the locking tabs to swivel into position. Continue turning each screw clockwise until you feel resistance, securing the unit to the back surface of the drywall.
A technical installation line drawing labeled with the number 4 in the top-left corner, detailing how to secure the speaker mounting clamps: Fastening Action: A hand at the bottom uses a screwdriver engaged with a front-facing screw head on the speaker bezel. Circular arrows around the screwdriver shank indicate turning clockwise to tighten. Clamp Mechanism Movement: Curved and downward-pointing arrows above the mounting bracket show that turning the screw causes the dog-leg clamp ear to swing outward and move downward. The clamp ear pulls down tight against the top surface of the ceiling material to sandwich the ceiling board securely against the outer front bezel.
5.) Before replacing the grill, attach the provided strips of adhesive to the speaker. They will help to hold the grill in place. Gently push the grill into the corresponding grooves on the speaker face until you feel some resistance.    
A technical installation line drawing labeled with the number 5 in the top-left corner, detailing the final grille reattachment step: Mounted Speaker Housing: Shows the installed circular ceiling speaker facing downward, displaying the center tweeter, woofer cone, inner screw mounting holes, and outer bezel ring flush against the ceiling surface. Grille Installation: A round, mesh metal grille is positioned directly below the speaker assembly. Two large upward-pointing arrows on the left and right indicate pressing the grille firmly upward into place to snap or magnetically attach it back over the exposed speaker faceplate.

Side Profile & Measurements (Right): A lateral cross-section diagram detailing the front grille curve, mounting flange, rear driver basket, clamp assemblies, and magnet depth: Overall Outer Diameter: A vertical dimension line spanning the total height of the curved front grille faceplate measures 9.01" (9.01 inches). Cutout Diameter: A vertical dimension line across the rear mounting chassis indicates a cutout opening requirement of 7.6" (7.6 inches). Mounting Depth: A horizontal dimension line at the bottom extending from behind the outer mounting flange to the back of the clamp structure measures 2.91" (2.91 inches). Total Depth: A horizontal dimension line at the top measuring from the front edge of the convex grille to the back of the mounting assembly indicates a total depth of 3.1" (3.1 inches).
