MB Quart Reference Series Speakers

Ohhh The 21st Century!

Technology has come a long way! For many years the construction for speakers was very simple; usually steel, foam, and paper. This worked fine but as the technology world advanced, car speakers needed to be updated. In order to improve the overall system performance, the MB Quart Reference Series speakers were introduced.

Offering component or coaxial speaker system with a 30mm tweeter, these systems provide deep and powerful sound. Each speaker features a low resonance cast ABS composite basket which allows the magnetism to be focused at the speaker providing louder sound with less power.

Standard foam material never lasted. Test after test, speakers and subwoofers with bland foam construction quickly dried out and easily deteriorated. MB Quart knew there had to be a more stable material to use which soon was discovered.  Additional improvements eventually included a UV treatment to increase reliability even more!

WideSphere Design

The Titanium WideSphere tweeter is a new inverted dome design providing 30 kHz of usable frequency range. The unique tweeter is designed to provide equal performance in both on-axis and off-axis configurations. With 180 degree sound dispersion technology, the tweeter eliminates high frequency loss allowing you to position or mount almost anywhere! Flush, angle, or top mounting methods are held securely with aerospace adhesives creating a long lasting, durable installation.

Crimping and Stripping?

Forget about crimping conductor end sleeves! Spring loaded terminals can be connected twice as fast making your install quick and easy. The connection is tight and resistant to all sorts of vibrations allowing you to be stress free when it comes to any loose wires.

 

Grill or No Grill

The Component speakers also feature a grill piece with removable mesh for a progressive look. As compared to Onyx series, Reference speakers offer better frequency response and more versatile options with enclosures.

Passive vs Active Crossovers

You may have heard the term “crossover” before. No, i’m not referring to SUV/hatchback vehicles or Chris Paul doing work on the court. I am in fact referring to audio crossovers. Most speakers are not going to be able to reproduce the entire spectrum of musical frequencies without distorting. For this reason, crossovers are put in place to separate frequency bands in order to get the best performance. There are two type of crossovers: passive and active.

Passive Crossovers

2-Way Passive Crossover

One of the main differences between the two is that passive crossover networks are unpowered which means there is no external power source.  They use capacitors and inductor coils to passively send frequencies to their desired drivers.  For example, in component speakers,  the crossover will passively send the high frequencies to the tweeters and the mid and lower frequencies to the mid bass drivers.  They will be wired in-line between the speakers and amplifier.  The amplifier’s output will be connected to the crossover’s input and the mid-bass driver and tweeter will be connected to the crossover output.  The disadvantages with passive crossovers is they are not usually adjustable and will actually cause a loss of wattage.

Active Crossovers

Active crossovers are a different story.  They are essentially electronic circuits that divide the frequencies. They use the input side of the amplifier rather than the output like a passive crossover does.   It is a common conception in the audio world that active are more accurate and flexible than passive crossovers.  Active crossovers are adjustable and have variable filters such as low-pass,  high-pass, and gain.  They also have deeper crossover slopes.  This allows for a more customized and desirable sound for the user.  Another advantage to active crossovers is their ability to allow bi-amping.  This means you can use two amplifiers channels to power multiple drivers.

Usually, a component set of speakers will come with a passive crossover. However, the general consensus is that active crossovers are more accurate and a lot more flexible.  However, if you are looking for a good fixed signal then there is nothing wrong with passive crossovers.  Ether way you’re going to need one or the other in your audio system so what are you waiting for?

Car Sound Staging and Acoustics

Focal No. 7

The Stage is Set

Many people are convinced that buying high quality car audio equipment will automatically guarantee them a top notch sounding system.   Fact of the matter is, there are many factors to take into consideration when installing aftermarket sound components in your vehicle.   Sound staging is one of the most important aspects in that it can make the difference between a good system and a great one.  The basic concept of sound staging can be best described as trying to recreate a stereo recording as a live performance.  Think of the basic format of a band:  You have a singer, one or two guitarist, a bassist and a drummer.  Someone who has proper sound staging should be able to listen to the recording and hear the singer in the center, the guitarist on the left, the bassist on the right, and the drummer behind the singer.

Speaker Placement

Sound Staging

The placement of a vehicle’s speakers can drastically affect its sound staging. Common vehicles usually only have a standard 4 speaker system.  This can often result in poor sound staging creating a very artificial sound.  However, this can be improved by adding speakers such as the Infinity Reference 6032cf. The Unipivot feature allows the tweeter to be pointed at the listeners location even when the speaker is mounted off axis. Passionate audiophiles will go above and beyond to ensure that their speakers are in locations that will provide optimum performance.  This might include modifying door panels or building custom kick panels to accommodate midbass drivers and tweeters.  Some may create mounting devices which allow them to raise the speaker above the dash for improved imaging and staging.  Installers might achieve better sound staging by adding additional speakers to the equation in locations such as pillars or under seats.

Interior Acoustics

Sound StagingA vehicle’s interior characteristics can help determine sound staging as well.  Different surfaces will have various responses to sound waves depending on how they absorb or reflect them.  For instance, a surface such as glass will be reflective and cause sound waves to bounce around.  A surface such as upholstery will cause sound wave to be absorbed.  This can greatly affect how your speakers and subwoofers reproduce music.  For example, if you were to put identical sound systems in a Rolls Royce and a Toyota Corolla, they would sound very different.  Adding a digital sound processor such as the JBL MS-8 can improve staging significantly with its automatic time correction feature, allowing the sound from each speaker to reach the listener simultaneously.  Audiophiles will often apply sound dampening material to door panels and trunks in order to control interior surfaces and reduce unwanted vibrations.

Let’s be honest, there is no perfect sound system, but understanding how to take advantage of every small detail can mean a world of difference.

Coaxial vs. Component Speakers

By Gideon V. – Sonic Electronix Editor

Ever wonder about the differences between coaxial and component speakers? Your host Seth Wilde gives a complete breakdown on component vs. coaxial speakers in the latest episode of SonicElectronixTV, our YouTube channel. This episode is actually part one of an ongoing series on car speakers.

If you are looking to purchase a set of auto speakers, you are probably wondering what the difference is between coaxial and component speakers. Coaxial speakers are essentially one full-range speaker. A coaxial speaker has a midwoofer and tweeter attached. The coaxial speaker has one terminal and one small built-in crossover, which is used to separate the frequencies running to the tweeter and the crossover. The Kicker KS650 is a great example of a traditional coaxial speaker.

Component systems have a mid-range speaker, a tweeter and a crossover. The tweeter does not arrive mounted onto the middle of the woofer, because the system comes with a separate tweeter and crossover. Some component systems allow you to manually mount the tweeter in the middle of the woofer, or you can opt to mount it elsewhere since the tweeter is separate from the woofer. The crossover is also separate from the woofer, so you can choose where to mount it. Unlike the coaxial speakers, the component systems are first connected to the crossover, then to the speaker and finally to the tweeter. While coaxial speakers require one input connection with the speaker wire running directly from the amp, a component system will require three different connections and three sets of speaker wire. Precision Power PPI 356cs is an example of traditional component speakers.

If your car has one speaker per door panel, coaxial speakers are probably the way to go. Component systems require a more advanced install, but for vehicles with separate tweeters, they are a good option. Component systems will likely give you a higher quality sound too.
