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 ft3 net volume, 0.06 ft3 per speaker, 0.049 ft3 port.

Gross Volume: 2.5 + 0.06 + 0.06 + 0.049 = 2.665 ft3 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) x (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.

In contrast, the Clarion SFW series primarily focuses on versatility and space-saving design. These shallow-mount subwoofers are ideal for vehicles with limited installation space. Despite their compact size, SFW subwoofers do not compromise on sound quality, producing impressive bass that can rival traditional subwoofers. The advanced cooling system integrated into these models allows them to perform efficiently without overheating, making them suitable for various acoustic applications.

The Clarion SRW series is designed for those who crave a premium audio experience. These subwoofers utilize cutting-edge technologies such as high-damping rubber surrounds and double-stacked magnets, which contribute to superior sound fidelity and minimal distortion. The SRW subwoofers are optimized for both sealed and ported enclosures, providing flexibility in setup to meet individual preferences. The innovative voice coil design also enhances heat dissipation and power handling, enabling these subwoofers to deliver consistent performance even under extreme conditions.

All three series incorporate user-friendly installation features, including easy-to-follow wiring diagrams and adjustable sensitivity controls. Their sleek designs ensure they integrate seamlessly with various vehicle interiors while appealing to aesthetics.

In summary, whether users seek powerful bass from the SW series, compact solutions with the SFW line, or premium audio performance from the SRW models, Clarion offers a diverse range of subwoofers that cater to the needs of every car audio enthusiast. With their commitment to quality and innovation, Clarion continues to set benchmarks in the automotive audio landscape.
