Pros:

  • Best of 6.5-Inch speakers
  • Great customer service
  • High-quality build
  • 1-year warranty

Being the largest speaker in the GTO line, the GTO629 works great. It sports the same engineering as the GTO639 (reviewed below), which provides an amazing combination of clarity and power. We’re talking about a 6 1/2-inch speaker that is both polypropylene and mica-reinforced.

The speaker weighs about 10 pounds. However, the price is still a pretty good deal for what you get. When you buy this speaker, you also get a 1-year warranty from the manufacturer and a 30-day money back guarantee with it, a definite plus in our books.

The speaker has a resistance of 4 ohms that means you will need a 4-ohm stable amp to use it. Fortunately, if you have a receiver-amplifier combo, the 4 ohms should be no problem.

Frequently Asked Questions (FAQ)

What is the best 6.5 inch car speaker?

If you’re looking for the best 6.5 inch car speaker then look no further than Polk Audio DB651. This has an impeccable build quality, great sound, looks cool and comes at an affordable price.

It is no doubt that Polk Audio DB651 is one of the best speakers in the market. Other options which can go head to head against Polk Audio DB651 are Pyle Pro PDMIC6865 and Kicker DS625.

What are the loudest 6.5 speakers?

Loudness is a subjective attribute that's hard to compare between products. Manufacturers rarely are forthcoming with decibel ratings when describing the sound of their products.

After hours of research, we used the Schebler True RMS Power Test Kit to determine which speakers had the best sound quality ratings. We also asked reviewers, audiophiles, and everyday users which speakers they preferred musically versus just on loudness.

What are the loudest 6 1/2 inch speakers?

Generally, bigger speakers mean a bigger sound. However, things get more complicated than just back size when it comes to finding speakers with more decibels. Larger speakers need more power to actually get to more than 70dB. Two smaller speakers in the same price range as one larger speaker will typically pack a bigger sound, but only if the total wattage of the system matches the larger speaker.

A similar trick is to compare the sensitivity rating, which gives a good indication of how much power the speaker will need to reach a certain volume. The inverse square law means that if you double the distance between the speaker and your ear, you will need four times the power to reach a similar volume. That means when you are looking for speakers for different applications, it’s important to make sure you match the sensitivity rating to your need.

Do 6.5 speakers have good bass?

A pair of 6.5” speakers will be able to handle bass just fine, and some of the larger sizes will be able to do even better. A pair of 6.5” speakers can handle a tight bass range of up to 80 Hz (called 80 Hz or 80 Hz bass) and this is the highest range possible. The lowest frequency you can expect out of a pair of 6.5” speakers is 40 Hz, and this will require certain specifications to reach that frequency.

Most of the inexpensive brands you find for an entry level car will have limits of around 70 Hz on bass. Some more expensive brand will have a specs limit of 90 Hz, and the expensive brands will generally have a limit of 100 Hz.

Conclusion

Do you consider yourself a "sound snob?" Do you want the power of a Wood tweeter? Do you want a truly high-end feel and functionality when you listen? Check out the Polk db651. These speakers bring the best technology to your sound system. In the faceoff between the Polk db651 and another excellent speaker, the Infinity Kappa 693.9i our experts clearly preferred the polished sound and powerful bass from the Polk.
