Those who want a high-end listening experience typically opt for 6.5″ speakers, which are popular in compact and subcompact cars. In-car speakers with a 6.5-inch diameter are the most widely used size since they can be installed in a wide variety of vehicles. You can get them in both midrange (treble-only) and full-range (coaxial) varieties. It’s possible to improve your car’s audio system by installing new 6.5-inch speakers while avoiding the expense of swapping out the entire factory setup.

Look at Sonic Electronix’s five best-selling 6.5″ full-range car speakers of the year based on reviews from actual buyers!


Durability: 4.7 | Value: 5 | Features: 4.7 | Design: 4.9 | Usability: 4.9

The N-Series raises the bar for what it means to be “Entry Level,” with superior sound quality and reliability that leaves the competition in the dust. The components and layout of the NVX NSP65 were chosen for their superior performance.

The NSP65 6.5″ Speakers are built to last and sound great without breaking the budget. The mid and low frequencies are reproduced faithfully by the sturdy yet lightweight polypropylene cone material.

Achieving pinpoint accuracy is facilitated by the Nitrile Butadiene Rubber Enclosure’s linear bearings. While the Stamped Steel Basket ensures the speaker stands firm and strong for years to come. Last but not least, the High-Temperature KSV Voice Coil offers optimal current distribution and heat dissipation.
Together, these components can produce powerful, full-range speakers.

The NSP65’s 20mm silk dome tweeters faithfully reproduce the NSP65’s luscious treble, making it sound incredibly warm and smooth. Usually, this material is reserved for high-end component systems, but NVX has included it in their affordable speakers.

Thanks to the built-in filter network in this speaker, attaching them to a wall or door is as easy as plugging in the wires. The N-Series also features 3-1/2″, 4″, and 5-1/4″ round speakers, as well as 4″x6″, 6″x8″, and 6″x9″ oval options. You needn’t look any further than the NVX N-Series Speakers if you’re shopping for a set of speakers that puts excitement before frills.

“Great budget speaker” – ★★★★★

I put these in the front doors and some NVX 6x9s in the rear deck on a Cobalt to replace blown factory speakers. They were just running off the (extremely weak) factory GM radio.

I was very, very impressed with their performance as a budget speaker. The tweeters were bright without being too harsh, and the bass response was unreal for the tiny amount of power they were getting from the head unit. Now, they didn’t slam like subs or anything, but it was solid bass.
