A Closer Look At Car Audio Crossovers

Car audio crossovers are a class of electronic filters designed for use in audio applications such as hi-fi. A dynamic loudspeaker driver that is commonly used is incapable of covering the entire audio spectrum all by itself.

Crossovers split the audio signal into separate frequency bands which can be handled by individual loudspeaker drivers optimized for those frequency bands. Let’s take a closer look at Kenwood’s KE-600 Crossover, KPX-F801 Crossover and Kenwood KPX-L101 Crossover.

Kenwood KE-600 Crossover

Kenwood KE-600, one of the most advanced signal processors, is a 6-Way electronic crossover with built-in parametric equalizer and a DC to DC power supply for high voltage outputs and low noise.

It has input selection, phase switching, variable level controls and the following outputs: subwoofer, low-pass, low-cut, high-cut and high-pass. It is a great component for multi-amp installations and is available for around $370.

Features

● DC to DC converter.

● High-frequency output.

● Input selector.

● Different phase switches.

● Subwoofer output from 30Hz to 800Hz (low-pass).

● 6-way multi-amp configuration.

● Variable level controls.

Kenwood KPX-F801 Crossover

Kenwood KPX-F801 Crossover is a 3-way passive crossover network. It is available for around $75.

Features

● Guard circuit that protects against excessive tweeter inputs.

● Special capacitors and inductors for audio purpose.

● Phase inverter switch for midrange and tweeter.

Kenwood KPX-L101 Crossover

Kenwood KPX-L101 Crossover is a low-pass passive crossover network. It is available for $50.

Features

● Special capacitor and inductor for audio purpose.

● 80Hz crossover.

Remember, an audio crossover splits the incoming audio signal into separate bands that do not overlap at all, and which, when added together, gives the signal unchanged in both frequency and phase response.

Car GPS – 3 Benefits Apart From Finding Your Location

Most people are very thankful to have a car GPS system installed in their vehicles because it helps them navigate with a great deal of ease. These high tech devices help drivers find places that are hard to locate because of unfamiliarity since they mark the location of the vehicle on a road map. Like most people who use these devices, you are sure to appreciate this feature which is after all the main benefit it offers. However, you will also be glad to know that a car GPS system also offers many more benefits. Needless to say, all GPS systems do not necessarily offer the same features and their prices vary accordingly.

Some of the additional benefits offered by vehicle GPS devices include:

1. Alerting of emergency services in case your vehicle breaks down or is involved in an accident. This can prove to be a lifesaver in certain situations, especially when the people in the car are not able to call for help themselves. This is generally a paid service but plenty of people feel that it is a worthwhile investment for very obvious reasons.

2. Helping the law enforcement authorities locate your car in the event that it has been stolen. The police will be able to track your car’s movements with absolute accuracy thanks to its GPS device. This will also help minimize the damage to your car since you’ll be able to get it back from the criminals before they have had a chance to strip it of its valuables.

3. Providing you with information about nearby places of interest. If you generally spend time looking for restaurants, hospitals, ATMs, gas stations and the like then your GPS device can be programmed to pop up information about nearby places that you seek. It will also give you directions to reach the place in addition to the estimated driving time; all extremely useful information that can help you to drive better.

Make sure that you select the best possible car GPS system for your vehicle based upon the features that it offers. Be sure to select a device of the right size so that it does not take up too much place on your car’s dashboard. Price is also a very important factor to be considered. The many options available in the market these days ensure that you will be able to find the right device at the best possible price.

Tips on Improving Your BMW Car Audio

Okay…you own the “Ultimate Driving Machine,” and even though you may not speak German, you have a pretty good idea of what freude im fahren is. The right BMW car audio can only add to that “Joy In Driving” of course – and the right BMW car audio deserves only the best BMW speakers.

The BMW car audio system is already pretty impressive, but a good thing can always be made better – particularly if your BMW is an older, yet still serviceable model built before the advent of such wonders as the iPod or satellite radio.

In fact, just having the right BMW speakers can be the difference between BMW car audio that is merely “great” and that which is – as the Germans would say – ausgescheisnet!! (the word ausgescheisnet has no direct English translation, but is several degrees beyond wunderbar.)

If you are thinking a upgrading your BMW speakers, you will probably want to go with coaxial speakers, as these are easier to install and include their own drivers and crossovers. These BMW speakers are suitable for most audiophiles, but if your tastes run less toward Muddy Waters or Bruce Springsteen and more toward the the New York Philharmonic or St. Martin-In-The-Fields Academy Orchestra, separates will provide the best sound quality when it comes to those ultra-high violins and piccolos and deep, rumbling contrabasses and tubas.

If you really want to take your BMW car audio to the next level however, consider installing horns. These type of BMW speakers are expensive, and you may need to install an equalizer – but they are second-to-none when it comes to picking up mid-to-high range frequencies.

For those who want to separate the vocals or solo lines from the ensemble, center channel speakers are a good choice. These are specialized BMW speakers that can be installed virtually anywhere in the vehicle; their main function is to bring solo, vocal and melody lines to the forward part of the cabin.
