NOTES:

- This is the exact mounting depth of the driver, and does not include provisions for air flow from the vented pole piece. Clarion recommends at least 1" of clearance behind the driver to facilitate air flow and proper cooling.

3. Subwoofer Break-In Period

All new speakers require some amount of time to break in. Depending on the application, this may take between one and four weeks. To accelerate this process, you can manually 'break in' your subwoofer before installing it. With the subwoofer sitting on a scratch-resistant surface, connect it to an amplifier and play a 25Hz sine wave at a level of 10V (8V for SFW) for a period of four to six hours. If you have any questions or concerns, please do not hesitate to contact your Authorized Clarion Dealer.

SFW ENCLOSURE DESIGN NOTE:

When constructing an enclosure for the SFW1051, please ensure the subwoofer is mounted in so the cone does not come into contact with any object (back of seat) when in use. This may require the installation of a grill or recessing the subwoofer into the enclosure. The subwoofer may be damaged if it comes into contact with any surface while in operation.

ENCLOSURE DESIGN NOTES:

• All enclosures should be constructed of at least 3/4" MDF. Particle board is not suitable for any enclosure and may result in the subwoofer system offering poor performance or the driver may be damaged.
• All panel joints should be sealed with appropriate caulking (latex or rope caulk). Do not use Silicone.
• All joints must be secured with screws or nails.
• Any panel exceeding 4 square feet in area (2'x2' or 1'x4' for example) should be braced internally for resistance to flexing
• All enclosure volumes are net and do not include the displacement of the subwoofer, ports or bracing. Please include these items in your enclosure calculations
• Clarion does not recommend the use of passive crossover networks with our subwoofers (inductors, chokes). Use an amp with an electronic crossover for the subwoofer to achieve optimum performance.
• Where noted, please use a subsonic filter to protect your Clarion subwoofer from over-excursion situations that may cause damage.
• All specifications are subject to change without prior notice.

6. Calculating Enclosure Dimensions

There are several important equations required to facilitate the calculation of enclosure dimensions. You will ultimately want to alter then dimensions for your enclosure to maximise the usable trunk space in your vehicle. The following example will show the general procedure to calculate the dimensions for an enclosure suitable for 2 SRW1251/SRW1252 subwoofers.

The calculations below will provide the enclosure depth, allowing you to construct your enclosure and enjoy bass, the way it was meant to be heard.

What you need to know: Example:

Maximum Trunk Width 35 inches

Maximum Trunk Height 15 inches

Net Enclosure Volume 2.5 cubic feet

Material Thickness 0.75 inches

Driver Displacement 0.06 cubic feet

Port Dimensions 4" x 7.5" long

Step 1: Measure the trunk width and height. Take note of seat belt mechanisms, strut tower protrusions and trunk opening size when measuring.

Eg: 35" wide by 15" tall

Step 2: Calculate the gross enclosure volume. This includes the net enclosure volume, plus the displacement of the drivers, port(s) and any bracing. There is no bracing being used in this example, however Clarion recommends an enclosure of this size be properly braced.

Eg: 2.5 ft ^3 net volume, 0.06 ft ^3 per speaker, 0.049 ft ^3 port.

Gross Volume: 2.5 + 0.06 + 0.06 + 0.049 = 2.665 ft ^3 or 4605.12 cubic inches.

Step 3: after subtracting the material thickness from the maximum width and maximum height, we can calculate the depth of the enclosure.

Eg: 4605.12 ÷ ((35-0.75-0.75) × (15-0.75-0.75) = 10.18 inches.

Step 4: Add the material thickness to the inside depth calculation and you have the outside dimensions of you enclosure.

Eg: 10.18 + 0.75 + 0.75 = 11.68 inches.

Width = 35" Height = 15" Depth = 11.68"

Step 5: You can now cut and assemble the panels for your enclosure. Make sure all joints are perfectly sealed and there are no air leaks anywhere. If you choose not to wrap the enclosure in carpet, use foam gaskets when installing the woofers to ensure an air-tight seal against bare wood.

Converting cubic inches to cubic feet

To convert cubic inches to cubic feet, divide by 1728

To convert cubic feet to cubic inches, multiply by 1728

Port Volume Calculation

The equation to calculate the volume of a round port is: Radius x Radius x Pi x Net Depth.

The net depth is the total depth of the port minus the thickness of the wood it is mounted in. For our example using a 4" port, 7.5" long, the equation would be: 2 × 2 × 3.1416 × (7.5 - .075) = 84.85 cubic inches or 0.049 cubic feet.

Wedge Style Enclosures

To further maximize the available storage space in your vehicle, you may choose to have the back panel of the enclosure follow the angle of the rear seat back. To calculate the volume of the enclosure, we need to find the average depth of the enclosure.

In our example, we had an enclosure depth of 11.68 inches. To calculate the top and bottom panel depths of a wedge enclosure, we need to know how much deeper the bottom is than the top. Follow these steps

Step 1: Place a board on the trunk floor and slide it to the base of the rear seats.

Step 2: Cut a small board that when combined with the thickness of the first board, is the total height of the enclosure. In our example with would be 15 inches, so the board would be 14.25 inches.

Step 3: Stand this board up on the first board and slide it toward the back of the trunk until it runs into the top of the seat back. Mark a line at the rear edge of the board.

Step 4: Measure from the line to the end of the bottom board. This is how much longer the bottom board is than the top. For this example, we will say it is 5 inches.

We now need to calculate the new depth of the enclosure, knowing the bottom is 5 inches deeper than the top. The average new depth of the enclosure is half of 5 inches, or 2.5 inches.

The top of the enclosure will need to be 11.68 - 2.5 = 9.18 inches

The bottom of the enclosure will need to be 11.68 + 2.5 = 14.18 inches
