How to Buy the Best 6x9 Car Speakers

How To Buy The Best 6x9 Car Speakers

1. Sound Quality

The sound quality should be one of the most crucial and perhaps the first factor to consider when choosing 6x9 speakers. Keep in mind that the main reason for buying these speakers is to give your sound system an upgrade.

When it comes to the sound quality, you need to make sure the speaker you get provides enough clarity as this is what ensures you get to enjoy your music.

It is important to note that the sound quality you get is not always apparent before you try out the speakers. However, other things like construction, sensitivity, and power handling should give you a clear idea of what to expect.

2. Power Handling

Power handling determines how much power the speaker can take with no distortion or damage. The rating is usually in watts, and here you need to consider both the peak and RMS power handling.

For the peak power, good 6x9 car speakers have a rating of between 100 and 1,000 watts, depending on the model and brand. However, something with a 600-watt rating like the Alpine SPE-6090 is often perfect as it strikes the right balance between price and power.

The RMS or nominal power, which is the speaker's actual operating power, can be as low as 45 watts, and for most of these speakers, it hardly goes beyond 300 watts.

It is also essential to make sure your sound system's head unit can handle the speaker's power because if it cannot, you need an external amplifier or have to upgrade the head unit.

3. Construction

The speaker's overall construction determines both performance and durability and is hence a crucial factor to take into account.

It is vital to ensure all speaker components from the cones to the surround and tweeters use high-quality materials for long service life. The speaker basket and coils should also be made from sturdy materials that can withstand abuse and vibrations.

4. Impedance

A speaker's impedance is the effective resistance to the flow of electric current, and it determines how much power you will need to run through the speaker. The higher the impedance, the more power you need to run the speakers.

Most 6x9 speakers have 4-ohm impedance, but you can get a few models rated 2 or 3 ohms. However, it is vital to make sure that the impedance matches your head unit's rating to ensure optimal performance.

5. Sensitivity

The sensitivity rating measures how loud a speaker will be to cancel out external sound and enhance the clarity of what you are listening to in the vehicle.

When shopping for 6x9 speakers and most other types, any model with a sensitivity of at least 87 dB at 1w/1m is often preferable. Something that delivers an even higher sensitivity than this, like the 93 dB at 1w/1m that you get with the Polk Audio DB692, is even better.

6. Frequency Range

Frequency response measures the range of highs and lows that the speaker's drivers, which are often a woofer and tweeter, can produce.

6x9 speakers that can capture most sound notes across the frequency spectrum are always the best. Most models have a frequency response of anything between 30 Hz and 25 kHz.

The lower the range can go, the better, as you can enjoy more of the subsonic frequencies like shallow bass notes.
