The key dimensions for the HDZ-W12 subwoofer are:

Overall Diameter: [12-7/8″] ⌀328 mm

Cutout Diameter: [11-1/16″] ⌀281 mm

Mounting Depth: [7-3/8″] 186.5 mm

Grille Protrusion from Mounting Surface: [1-3/8″] 34.8 mm

Displacement (Overall height from back to front of grille): Information derived from adding mounting depth and grille protrusion, total depth behind mounting surface + depth in front. The diagram shows [1-7/8″] 48.4 mm as the dimension from the mounting surface to the front of the cone surround, and [1-3/8″] 34.8 mm as the grille protrusion from the mounting flange. Total depth is [7-3/8″] 186.5 mm.

The key dimensions for the HDZ-W10 subwoofer are:

Overall Diameter: [10-7/8″] ⌀276 mm

Cutout Diameter: [9-1/16″] ⌀229 mm

Mounting Depth: [7-7/16″] 188.5 mm

Grille Protrusion from Mounting Surface: [1-3/8″] 34.7 mm

Displacement (Overall height from back to front of grille): Information derived from adding mounting depth and grille protrusion. The diagram shows [1-3/4″] 45.9 mm as the dimension from the mounting surface to the front of the cone surround, and [1-3/8″] 34.7 mm as the grille protrusion from the mounting flange. Total depth is [7-7/16″] 188.5 mm.

The DC Resistance (DCR) for the Status Series subwoofers is measured with the voice coils in series configuration.

To achieve a 2Ω load with one dual 4Ω voice coil subwoofer (HDZ-W12 or HDZ-W10) and a single amplifier, wire the voice coils in parallel:

1. Use a jumper wire to connect the positive terminal of Voice Coil 1 (VC1+) to the positive terminal of Voice Coil 2 (VC2+).

2. Use another jumper wire to connect the negative terminal of Voice Coil 1 (VC1-) to the negative terminal of Voice Coil 2 (VC2-).

3. Connect the amplifier’s positive output to VC1+ (or VC2+, as they are now common).

4. Connect the amplifier’s negative output to VC1- (or VC2-, as they are now common).

This configuration presents a 2Ω load to the amplifier. The provided diagrams show jumpers between the terminals on the subwoofer for this configuration.

To achieve an 8Ω load with one dual 4Ω voice coil subwoofer (HDZ-W12 or HDZ-W10) and a single amplifier, wire the voice coils in series:

1. Use a jumper wire to connect the negative terminal of Voice Coil 1 (VC1-) to the positive terminal of Voice Coil 2 (VC2+).

2. Connect the amplifier’s positive output to the positive terminal of Voice Coil 1 (VC1+).

3. Connect the amplifier’s negative output to the negative terminal of Voice Coil 2 (VC2-).

This configuration presents an 8Ω load to the amplifier. The provided diagrams show a jumper between VC1- and VC2+ on the subwoofer for this configuration.

To wire one HDZ-W12 or HDZ-W10 subwoofer with two amplifiers (one amplifier for each 4Ω voice coil):

1. Important: Please remove any jumpers between the voice coil terminals on the subwoofer when using this configuration.

2. Connect the positive output of Amplifier 1 to the positive terminal of Voice Coil 1 (VC1+).

3. Connect the negative output of Amplifier 1 to the negative terminal of Voice Coil 1 (VC1-).

4. Connect the positive output of Amplifier 2 to the positive terminal of Voice Coil 2 (VC2+).

5. Connect the negative output of Amplifier 2 to the negative terminal of Voice Coil 2 (VC2-).

In this configuration, each amplifier sees a 4Ω load from its respective voice coil.

To wire two HDZ-W12 or HDZ-W10 subwoofers to a single amplifier for a 4Ω total load, follow these steps (as shown in Example 3 of the application diagrams):

For each subwoofer:

1. Wire its two 4Ω voice coils in series to create an 8Ω load per subwoofer. To do this, connect the negative terminal of Voice Coil 1 (VC1-) to the positive terminal of Voice Coil 2 (VC2+) using a jumper on each subwoofer.

2. This leaves the positive terminal of Voice Coil 1 (VC1+) and the negative terminal of Voice Coil 2 (VC2-) as the main connection points for each 8Ω configured subwoofer.

Connecting the two subwoofers to the amplifier:

3. Wire the two 8Ω configured subwoofers in parallel to the amplifier.

– Connect the VC1+ terminal of Subwoofer 1 to the VC1+ terminal of Subwoofer 2. Then connect this common positive point to the amplifier’s positive output.

– Connect the VC2- terminal of Subwoofer 1 to the VC2- terminal of Subwoofer 2. Then connect this common negative point to the amplifier’s negative output.

This configuration wires each subwoofer to 8Ω, and then the two 8Ω subwoofers in parallel present a final 4Ω load to the amplifier.
