optimal crossover setting

We recommend using an active crossover with a 12 to 18dB per octave low pass filter slope, and setting it to an initial setting of 80 to 90Hz as a good starting point. This is an optimal crossover setting on most vehicles.

inverting phase

Depending on the placement of your subwoofer enclosure and associated components, it may be necessary to invert the phase of one or another of your system’s connections in order to gain better subwoofer/mid-range blending. Inverting the phase simply means switching the positive connections with the negative connections at the amplifier. If you choose to do this, invert the phase of only one set of speakers (either your mains, or your subs, never both).

low frequency cut-off for mid-range speakers in systems with subwoofers

Now that you have a subwoofer in your system, you may want to decrease the amount of bass going to your midrange speakers. This will get you better mid-range sound and increase the power handling. There are two ways to roll off the bass before it gets to your mid-range speakers. One way is to use

a “bass blocker,” a capacitor placed in series with the speaker input. Bass blockers are installed in series, one end connected with the positive lead from your amplifier and the other end connected to the positive lead of each of your speakers. Bass blocker capacitors (200 microfarad @ 100V, non-polarized) are available at any Radio Shack or electronic parts supply house. The other route is to use an electronic crossover device that allows filtering below 100Hz or so. Find these devices at your authorized Polk dealer.

1201, 1240DVC specifications

Polk Audio, a renowned name in the realm of audio technology, has made significant strides with its impressive subwoofers, particularly the Polk Audio 1201 and 1240DVC models. These subwoofers are engineered to deliver deep, powerful bass, enriching any audio experience, whether it’s for music, movies, or gaming.

Starting with the Polk Audio 1201, this subwoofer features a robust 12-inch cone that efficiently reproduces low frequencies, ensuring that users feel the impact of every beat and explosion. One of its standout characteristics is the use of a durable, but lightweight composite material that improves sound quality while reducing distortion. This allows for clear, resonant bass at various volume levels. The 1201 also incorporates a high-efficiency motor structure, which maximizes power handling and provides a competitive edge over many other subwoofers in its category.

On the other hand, the Polk Audio 1240DVC presents even greater capabilities with its dual voice coil setup. Each coil can be powered independently, offering users greater flexibility in wiring configurations. This feature is particularly advantageous for audiophiles looking to customize their setups. The 1240DVC utilizes a larger 12-inch cone and an innovative suspension system that enhances linearity, resulting in more accurate sound reproduction. Additionally, the subwoofer's vented design allows for improved airflow, reducing heat and allowing for longer playtime with consistent performance.

Both models showcase Polk Audio's commitment to quality, featuring a robust build that can withstand the rigors of intense audio sessions. They incorporate advanced technologies such as Dynamic Balance to minimize distortions and ensure a cleaner sound profile. Furthermore, both subwoofers are designed to integrate seamlessly with various home theater systems, making them versatile choices for both casual listeners and serious audiophiles.

In terms of installation, the 1201 and 1240DVC come with detailed guidance that simplifies the integration process. Their dimensions and designs allow them to fit comfortably into most setups, whether in a car or home environment. Overall, the Polk Audio 1201 and 1240DVC are stellar choices for anyone aiming to enhance their audio experience with powerful, precise bass. Their cutting-edge features and technological advancements solidify Polk Audio’s reputation for delivering superior sound quality in a variety of settings.
