Building an Enclosure

To work properly, the walls of the enclosure must be rigid and not flex when subjected to the high pressures generated by the speaker's operation. For optimum performance, we recommend using 3/4" MDF (Medium Density Fiberboard) and internal bracing. The enclo- sure should be glued together and secured with nails or screws. MDF is porous; therefore, it is suggested to also seal the outside walls with polyurethane.

Calculating Volume

Calculating volume is merely a matter of measuring the dimensions in inches and using the formula:

 

Box Volume =

Height x Width x Depth

 

 

 

 

1728"

 

 

 

(cubic feet)

 

 

 

 

 

 

 

 

 

 

 

 

If two facing sides are of uneven length, add them together and divide by two to take the average. Using this number will give you the volume without the necessity of calculating the box in sections and adding the sections together. The thickness of the baffle material reduces the internal volume so this must be subtracted from the outside dimensions to determine the internal volume. The speaker itself also reduces the internal volume. The amount of air displaced by each model is listed on the specification sheet and should also be subtracted from the gross volume calculation.

Subwoofer Crossovers

There are two operational types of crossovers, passive and active. Passive crossovers (coils or inductors) are placed on the speaker leads between the amplifier and speaker. An active crossover is an elec- tronic filter which separates the audio signal fed to different amplifi- ers. For optimum subwoofer performance, we recommend using an active 80-100Hzlow-pass crossover at 12dB/octave.

RFP-1418/1815, RFP-1412/1812, RFP-1415/1815, RFP-1410/1810, RFP-1408/1808 specifications

Rockford Fosgate, a renowned name in the audio industry, has consistently delivered top-notch subwoofers that elevate the listening experience. Among its impressive lineup, the RFP-1415/1815, RFP-1410/1810, RFP-1412/1812, RFP-1418/1815, and RFP-1408/1808 stand out for their powerful performance and advanced technology.

These subwoofers are engineered to deliver deep, resonant bass that enhances any audio system. One of their standout features is the advanced cone design, which optimizes sound output while ensuring durability. The cones are crafted from high-quality materials that allow for superior flexibility and stiffness, contributing to a more precise bass response. Additionally, the subwoofers feature a large voice coil that enables them to handle greater power and operate efficiently even at high volumes.

The RFP series embraces cutting-edge technologies that enhance their overall performance. The use of high-temperature voice coils minimizes distortion, ensuring that your music sounds clear and undistorted. This is crucial for bass-heavy genres where muddiness can plague lesser quality subwoofers. The incorporation of an innovative cooling design ensures that the voice coils remain at a manageable temperature, thus prolonging the life of the subwoofer and maintaining performance over time.

Another significant characteristic of these subwoofers is their flexibility in installation. They can be configured in various setups, making them suitable for a wide range of vehicles and audio systems. Whether you're looking for a single subwoofer setup or a more complex multi-subwoofer arrangement, the RFP series adapits easily to your needs.

The RFP-1415/1815 features a dual 15-inch setup designed for exceptional bass impact, while the RFP-1408/1808 is a compact 8-inch option that still delivers impressive low-frequency response. Meanwhile, the RFP-1410/1810 and RFP-1412/1812 offer versatile 10-inch and 12-inch sizes, allowing for a balance between size and performance.

While aesthetics might not be the primary consideration for all users, these subwoofers come with a rugged yet sleek design that complements any sound system setup. Their robust construction not only contributes to their sound quality but also ensures they can withstand the rigors of daily use. In summary, Rockford Fosgate's RFP series is engineered for those who demand powerful, deep bass without compromising on clarity or durability.
