The first thing to do is to think about the possible limitations of your car’s sound system, and determine what is best for you. There are many places to find car speakers—the Internet, custom audio stores, manufacturers, etc. All of these options offer in-depth specifications regarding their available 6.5-inch car speakers but here are a few things to guide you in finding the ones right for you.
6.5-inch car speakers offer a distinct performance advantage over their 5-inch brethren—an audible improvement in low frequency reproduction. The lowest audio frequencies have always required massive air displacement in order for our ears to accurately filter the sound. Small cones simply cannot move enough air mass to reproduce the very lowest tones, but 6.5-inch deliver up to 20 hertz improvement in low-end response, which is a bit closer in reproducing the full audio spectrum.
Here are some of the best speakers to choose from.
Pioneer’s PRS series offers two models for $500 and $550 per pair, respectively. At the high end price-wise, the C720PRS series is based on exceedingly light, yet stiff 6.75-inch woofers and adjustable tweeters. Pioneer’s slightly larger diameter results in very good low-end response, good power handling capability and extreme flexibility of tweeter installation and performance options. Pioneer’s D-Series retains the components design at very affordable price points. There are two 6-inch models—TS-D1720C and TS-D720C— that also use 6.75-inch low ends, adjustable tweeters and separate crossovers for a very reasonable $220 and $200 per pair, respectively.
JBL’s Power series is a “best buy,” based on a larger 6.5-inch 2-way component system. Separates provide many more options during installation. JBL’s Power series range from low $200 to $450 per pair. JBL’s Grand Touring series offers a low end component choice for around $250 and 6.5-inch configurations in both 2-way and 3-way coaxial design for under $200 retail.
Infinity, originally created as a competition brand for JBL by the company that owns them both, Harman Industries, is similarly based on superior build quality and performance standards. Three Infinity component speakers are offered in the 6.5-inch configuration: the Kappa Perfect Series 6.1, the Kappa Series 60.9CS 2-ways and the more economical Reference Series 6030CS 2-way component system. The Kappa Perfect’s biggest difference from its two companion models is its 1-inch deep tweeter. With a median street price of $250/pair, these component speakers look like a bargain.
The Infinity Kappa 60.9CS is the “better” of this “good/better/best” trio. There’s the improved low frequency response of the 6.5-inch mid bass/woofer, so called because the very lowest bass is from 20 to 40 Hertz. With an adjustable tweeter level and web/street prices as low as $129 for a pair of these speakers, they offer a great bang for the buck.
Infinity REF6030CS is the base model of the Infinity component series. It offers excellent low-end frequency response down to 35 hertz, is ideally matched to standard vehicle wiring, and includes tweeter level adjustment on the crossover. Available for $119.99, 6.5-inch component speakers are readily affordable.
It really is a buyer’s market for car audio speakers, and given the variety of vehicle interiors, it is really the most important thing to get what you want. Go to your local car audio shop or Best Buy, and audition several speakers with different amplifiers from the units on display.
Although these are only of the few things to think about when choosing car speakers, the ideas above should help you when shopping. By weighing the pros and cons of each type of 6.5-inch car speaker, you should be able to whittle the list down to one. Remember, there is no perfect car speaker but there is one for each one of us.
