Many car audio customers ask if it’s necessary to choose a specific size or type of speaker to play certain kinds of music. Do paper-cone midrange drivers handle classical music better? Do 15-inch subwoofers reproduce kick drums with more accuracy? Let’s take a look at how sound works and explain the benefits and drawbacks of different speaker sizes and designs.

Frequency Content in Music

Whether you’re listening to Nine Inch Nails, Neil Young, Taylor Swift or Metallica, all performers and musical instruments cover a surprisingly wide range of frequencies. The male voice typically covers frequencies from 125 Hz to over 3 kHz. For female singers, their voices typically fall between 200 Hz and 4 kHz.

When it comes to instruments, their frequency ranges are much wider. An upright piano extends from less than 30 Hz to more than 4 kHz with harmonics that extend even higher. A triangle has significant energy right up to 15 kHz. What most people don’t expect is that an instrument like a snare drum covers a surprisingly wide bandwidth. The fundamental is at 275 Hz, but harmonic content extends solidly up to 6.5 kHz before starting to roll off.

The Importance of Audio System Frequency Response

For a high-quality car stereo system to sound good, we need the system to cover as much of the audible frequency range as possible. For most of us, this means we need everything from deep bass at 30 Hz or lower up to the highest of highs between 15 and 20 kHz. To achieve this, we need at least two speaker sizes; in practicality, three sizes work better.

The next requirement is that the frequency response of our sound system needs to be relatively smooth with a pleasant balance. Some people like a little more bass while others like laid-back high-frequency reproduction or a little extra sizzle on top. In almost every blind test performed by speaker manufacturers, the midrange response (150 to 4,000 Hz) of the system should be as flat as possible for vocals to sound accurate.

The Three-Way Audio System

Most audio systems installed in vehicles use a three-way design. The term three-way describes the use of three differently sized speakers, each operating in different frequency ranges to recreate the recording. In a factory-installed sound system, you may have an 8- or 10-inch subwoofer in the rear parcel shelf or cargo area to reproduce bass frequencies below 80 Hz. A 5.25-inch or 6.5-inch woofer in each of the doors will play from 80 Hz up to the crossover point with a midrange driver on the dash or a tweeter in the sail panel. For a tweeter, the crossover is likely around 4 kHz; for a midrange, it could be between 250 and 450 Hz. Using multiple speakers reduces system distortion because small speakers aren’t being asked to work at high excursion levels to produce low-frequency information.

Does Speaker Size or Material Matter?

Does it matter what size speaker you use in your car audio system? To keep the answer short and sweet, larger speakers typically reproduce low-frequency information better. However, this doesn’t have to be directly associated with bass. A 2-inch midrange on the dash of a Jeep can play down to 400 Hz without any problem, whereas a 1-inch tweeter needs to be crossed over at 4,000 Hz.

The drawback of using larger speakers is that their output becomes directional at higher frequencies. An 8-inch woofer in the door of a sedan will need to be paired with a midrange in the dash to produce even sound throughout the listening environment. The phenomenon of speaker directivity is purely related to the cone diameter and not the speaker’s design or materials. Directivity is one of the reasons why some systems use a four-way design with dedicated midbass and midrange drivers.

So, back to our question about speaker sizes and music types. Does speaker size matter? In terms of the sounds the speaker is reproducing, speaker size does not correspond to a specific type of music, only to a specific range of frequencies.

Does Cone Material Affect Sound Quality?

Choosing a material for a speaker cone requires balancing three criteria: mass, damping and rigidity. For example, a metal speaker cone may be light and rigid but could run into problems with resonance at higher frequencies. Paper, plastic and composite cones all have their strengths and drawbacks. The speaker designer’s goal is to choose a cone material and design that will function without distortion within the desired frequency range. The speaker doesn’t know what kind of music is being played, nor does your source unit or amplifier.

How Do I Choose the Right Speakers for My Car Stereo?

When it’s time to upgrade the stereo system in your car or truck, visit a local specialty automotive enhancement retailer. They will inspect your vehicle to confirm speaker size and location, then suggest a combination of sizes to meet your needs. Your goal during the audition process is to choose a solution that sounds accurate and detailed, especially at high volume levels.

If you’re wondering how they’ll make sure the system sounds good with the music you enjoy, the answer comes in the form of tuning. If you include a digital signal processor (either as a stand-alone piece or one built into an amplifier), the installer can calibrate the system to ensure smooth response and the right amount of bass and high-frequency output to meet your needs.

If you drive an Audi car or SUV, your local specialty mobile enhancement retailer offers a variety of entertainment and safety upgrades. Whether you want to update the technology in an older vehicle, add heated seats to make a cold morning more comfortable or improve the sound system so your music sounds like you are at a concert instead of listening to a clock radio, your local specialty mobile enhancement retailer can help. Let’s look at a few popular upgrades common to Ingolstadt’s finest cars.

Audi Audio and Infotainment Upgrades

If you have an older Audi that will accept an aftermarket radio, upgrading to a solution that includes Apple CarPlay and Android Auto is a wise investment, especially if you spend a lot of time in your car. These voice recognition technologies let you ask your smartphone to send text messages, make phone calls or dial phone numbers without you having to take your eyes off the road. You can choose the song, artist or genre of music stored on your phone or pick from streaming services like Pandora, Tidal, Google Play Music or iHeartRadio to entertain you on the way to work.

Detailed and turn-by-turn navigation directions are available to the address or business of your asking. Navigation solutions like Waze and Google Maps work with Android and iOS-powered smartphones to ensure that real-time traffic information is used to optimize your route.

If you have a newer Audi, your local specialty mobile enhancement retailer can upgrade the factory-installed sound system to deliver reduced distortion, more output and, most importantly, dramatically better bass response.

Remote Car Starters and Convenience Accessories

Whether you live in the cold North or the balmy South, nobody wants to get into a car or truck that’s freezing cold or swelteringly hot. A remote car starter is a perfect solution in both cases. With the press of a button on a long-range remote or a quick tap on the screen of a smartphone application, the engine in your vehicle will start, and the climate control system can start making the vehicle more comfortable.

You may want to consider adding an alarm system to your starter to protect a nice set of wheels or to provide a warning if the car is jacked up. We mentioned smartphone control already. Did you know you can use an app on your phone to control your remote starter? These telematics systems also offer the ability to locate your vehicle and display that information on Google Maps, right on your phone. If you share the vehicle with family members or coworkers, you can check its location whenever you want.

Security and Accident-Avoidance Solutions

If your Audi didn’t come with a backup camera, adding one isn’t a problem. There are hundreds of camera options, and depending on your vehicle, we can integrate the camera with the factory color display in the dash, an aftermarket radio or a replacement rearview mirror with an integrated color LCD screen.

Another popular upgrade is parking sensors. These work like a backup camera, but warn you automatically when you are approaching an object.

Other safety options include blind-spot warning systems that use ultrasonic or radar sensors to let you know when a car, truck or motorcycle is in an adjacent lane. Many of these systems switch to a cross-traffic alert mode to provide warnings about oncoming vehicles when you’re backing out of a parking spot.

Rear-Seat Entertainment Systems

If you take road trips with your family, adding an overhead or replacement headrest entertainment system can turn that dreaded “Are we there yet?” into near silence for many hours. These video systems include wireless headphones that let your rear-seat passengers watch their programming in peace. Many systems can play DVDs or video files from a USB memory stick. Some even have built-in gaming systems to help pass the time.

Lighting Upgrades

If the headlights on your Audi just aren’t cutting it, many options are available to enhance what you can see once the sun sets. HID and LED headlight upgrades are very popular with older Audi vehicles that came with incandescent lighting systems. Many retailers can source and install replacement headlight assemblies if yours are looking a little ragged or faded.

Window Tint and Paint Protection Film

People choose to have the windows of their cars and trucks tinted to enhance the appearance of the vehicle, to improve its security or to make it more comfortable. A rich, dark tint can make a dramatic change to the way a car looks. If you are concerned about unscrupulous folk peering in your windows, window tint can help conceal the contents of your vehicle. Finally, choosing a ceramic or multilayer heat-rejecting tint film reduces the amount of IR heat energy from the sun that can enter your vehicle. These films are available in almost transparent shades for use on windshields, where legal, to block even more heat.

If you care about how your Audi looks, then you may want to inquire about paint protection film. This transparent film can be applied to any smooth surface to prevent impacts from rocks, gravel, sand or salt from scratching or chipping the paint. Originally developed to protect the leading edge of helicopter blades from damage during the Vietnam War, the urethane layer is amazingly durable yet can be easily replaced if damaged.
