CALCULATING ENCLOSURES

It is difficult to give exact box dimensions that are universal for all cars and trucks. It is for this reason that you must be able to calculate the space in which you have available in order to achieve the proper air volume required.

It is recommended to build your enclosure from 3/4" thick MDF (medium density fiberboard). Make sure the enclosure is sealed airtight.

Calculating External Volume

1.) To calculate box volume, measure the outside Width x Height x Depth of the enclosure. Example 12" x 14" x 9" = 1512".

2.) Next you must convert cubic inches into cubic feet. To do this, you must divide the cubic inch total by 1728". Example 1512 ÷ 1728 = .875 Cubic feet

Calculating Internal Volume

1.) To calculate the internal (net) volume of the above box you must first multiply the thickness of the wood you are using by Two (2). Example 3/4" x 2 = 1.5".

2.) Next subtract 1.5 from each of the outside measurements of the box.

Width

Height

Depth

12-1.5=10.5

14 -1.5 = 12.5

9 -1.5 = 7.5

3.) Multiply the new totals (H x W x D) Example: 10.5 x 12.5 x 7.5 = 984.375

4.) Next you must convert cubic inches into cubic feet. To do this, you must divide the cubic inch total by 1728" Example 984.375 ÷ 1728 = .5696 cubic feet.

QC154 specifications

The Quantum Audio QC154 is a high-performance speaker system designed for audiophiles and discerning listeners who demand exceptional sound quality. Combining advanced technologies and meticulous engineering, the QC154 delivers an immersive audio experience that is both powerful and nuanced.

One of the standout features of the QC154 is its dual 15-inch woofers, which are specifically engineered to produce deep, thunderous bass while maintaining clarity in the mid and high frequencies. The woofers utilize a proprietary cone material that enhances rigidity and minimizes distortion, ensuring that bass notes are not only loud but also well-defined. This makes the QC154 an excellent choice for both music enthusiasts and professional audio applications.

At the heart of the QC154 is its state-of-the-art crossover network. Quantum Audio has integrated a sophisticated 3-way design that utilizes high-quality components to ensure seamless integration between the woofers, mid-range drivers, and tweeters. This design allows for a wide frequency response, providing listeners with crisp highs, detailed mids, and robust lows. The tuning of the crossover is carefully calibrated, delivering an audio profile that is balanced across all genres of music.

In terms of build quality, the QC154 is constructed from durable MDF with a bass reflex design, which effectively enhances the low-end performance. The cabinet is reinforced to minimize vibrations, ensuring clean sound output even at higher volumes. Additionally, it is finished with a sleek, professional-grade veneer that not only looks great but also provides added durability.

Another notable technology featured in the QC154 is the high-efficiency neodymium magnet in the tweeter. This allows for exceptional high-frequency response and sensitivity, translating to a sound that is both lively and detailed. The result is an immersive soundstage that draws listeners into the performance, whether it's for casual listening or critical listening sessions.

The Quantum Audio QC154 is equipped with multiple input options, allowing for versatility in setup. It can easily connect to a range of audio equipment, including mixers, amplifiers, and home theater systems. Its compatibility with various audio technologies makes it a valuable addition to any audio setup.

In summary, the Quantum Audio QC154 blends premium materials and innovative design to provide an outstanding audio experience. With its powerful woofers, sophisticated crossover network, robust construction, and versatile connectivity options, this speaker system is sure to satisfy even the most demanding audio enthusiasts. Whether for concerts, studio monitoring, or home listening, the QC154 stands out as a top-tier choice for quality sound reproduction.
