Features 5

  • DURABLE CONSTRUCTION: Built to withstand the demands of the automotive environment, these speakers feature rugged construction and durable materials that can handle the vibrations, temperature fluctuations, and moisture commonly encountered in cars. The robust design ensures long-term reliability and consistent performance, even under challenging conditions.
  • CARBON FIBER CONE: These speakers feature a carbon fiber cone that offers lightweight yet rigid construction, allowing for accurate and responsive audio reproduction. The carbon fiber material helps to minimize distortion and break-up, resulting in clear and detailed mid-bass and mid-range frequencies.
  • 4 OHM IMPEDANCE: The speakers have a 4-ohm impedance, which makes them compatible with a wide range of car stereo systems and amplifiers. This impedance rating ensures efficient power transfer and optimal performance, allowing you to achieve maximum volume levels and sonic impact without straining your audio equipment.
  • HIGH-QUALITY SOUND: With their 6.5" size and optimized design, the HC-CMB65 speakers produce punchy and well-defined mid-bass and mid-range frequencies, enhancing the overall audio experience in your car. Whether you're listening to music, podcasts, or audiobooks, these speakers ensure that vocals and instruments are reproduced with clarity and realism.

Description

The Carbon series speakers were precisely engineered with sound quality and power handling in mind delivering a truly immersive listening experience. The speakers feature carbon fiber cones which greatly increase long term durability and a soft rubber surround which smoothes the responsiveness of the lower frequency range. The 1" silk dome tweeter delivers crystal clear higher frequencies and combined they cover the entire full range spectrum of sound. Factory speakers are made from cheap materials like paper and in most cases do not even have tweeters which means more than half of the audible frequency range is lost. Harmony Audio Rhythm series speakers are designed to directly replace the factory speakers dramatically improving sound quality and reproduce music like the artist intended. The speakers are available in a wide range of sizes and are constructed from high quality materials like polypropylene cones, durable rubber surrounds and 1/2" or larger PEI dome tweeters. Factory speakers come in a wide range of sizes and mounting configurations which is why Harmony Audio offers 7 different models. Many of them include multiple mounting hole positions so can be installed in virtually any vehicle. The speakers feature high powered but slim magnets that will fit into even the tightest door panel or shallow mount dash. Another unique feature is the silk dome tweeters which do not extend past the frame of the speaker which is important when installing a door panel back into its factory fit location.

Good speakers
Size: Midbass 6 1/2"
Best speakers for the price ran them through a amp and couldn’t even set them to the voltage they are rated for wouldn’t push the speakers to far though will buy again

Good quality and loud!
Size: Midbass 8"
great budget option! I put these in my demo truck and they have great sound quality and can be easily heard over the loud bass. With them being in a demo vehicle and them being so affordable I'm not so worried about them being damaged. But really they have good clarity and where a perfect fit for the custom door pods I made. Would recommend! ... show more

Not what I was hoping for, they can't handle the power at all.
Size: Midbass 8"
Just installed these tonight to replace some CT sounds 8in Midrange speakers in my 3 way setup. Needless to say these things can't handle the power at all. Got them cause I'm running the Monolith line of Harmony Audio subwoofers. While the subwoofers are really decent I can not say the same about the 8's midbass. I think I'm gonna return these and get my money back and go with a better quality brand. Maybe DS18 or something else. Edit 8/14/25: After checking my connection and my gain settings on my amplifiers I was able to get these to play nice and loud without them continuing to bottom out and sound distorted. These things once you get the gains settings on them right do come alive. I had to adjust my initial review from 2 stars to 4 stars. Wish they could take a little more power but they aren't bad at all for the price. ... show more

Can you put a price on happiness? Apparently 50 bucks is all you need.
Size: Standard 3 1/2"
It took me four tries to find these 3.5's but it was so worth it. They sound natural and clean without being harsh or fatiguing. They blend in nicely with the 6.5 CDT's I have in my front doors. I'm all about the sq and with some tuning and an amp, music is all around me. I was able to shoehorn them in the front dash of my Sonata with a bit of fabricating. Not too hard. I wish I had tried these from the jump. IMO these little guys don't get enough love. From the silk dome to the big magnet to the carbon cone and nice frequency response and sensetivity. Plus they feel solid and made to last. ... show more

Ok sound
Size: Standard 5 1/4"
The speakers have an ok sound. Not as loud or with as much base when compared to other brands of equal production ratings. If you are looking for an affordable replacement, this are the ones to buy.

Amazing sound
Size: Midbass 6 1/2"
I have 2 sets if these. Was powering them on the harmony 800watt 4 channel. They are loud and clear even at half tilt on my rca knob. Qent down to 1 set in my civic and still was able to hear it clearly over the bass. Will buy again and recommend them even for home audio set up
