Description

Introducing the Harmony Audio Carbon series competition grade subwoofers that feature a massive 2.5" voice coil and at least 2000 watts power handling or more! The subwoofer features a carbon fiber paper reinforced cone with a high roll foam surround for maximum SPL excursion. The massive double stacked magnet motor delivers earth shattering bass response and power handling capabilities that simple cannot be matched. Live in Harmony! Why do all Harmony Audio subs feature interwoven tinsel leads? The answer is simple we demand nothing but the best. A tinsel lead is a small wire that connects the voice coil to the input terminal and if you look at most other subs its positioned so when the subwoofer is playing the cone will actually slap into the leads creating a pop noise when playing. The advantage to an interwoven tinsel leads is both increased durability and performance which is what Harmony Audio is all about. The greatest enemy of a car audio subwoofer is heat which needs to be quickly dissipated for a sub perform correctly and is crucial to prolong the life of the subwoofer. Harmony Audio Rhythm, Alloy, Carbon & Monolith series subs feature large slotted vents directly under the spider which allows cool air to quickly reach all the sensitive components. The Flatline series features a unique fin shaped heatsink that transfers heat away from the voice coil. Cutting corners is not the Harmony Audio way and while other manufacturers may be cutting out features to save a penny we are focused on producing a superior performing subwoofer. Take the wire terminal for instance probably one of the most important features of the sub which is what handles the power transfer from your amp to the sub. Many other brands now use a cheap spade terminal that takes longer to install and who knows if it will even stay connected once installed. All Harmony Audio subs feature a spring-loaded push terminal that will accept direct speaker wire ensuring the ultimate connection and power transfer.

Don't Sleep on Harmony Audio... their products are legit!
Size: 2 Ohm Style: Two Pack
I am by no means an expert, or a professional when it comes to audio equipment, but what these units are producing and the amount of air they move, is not what you normally get at this price point. Usually the higher the price, the better the sound. Not in this case though, the price you're paying is for some wally world specials, but what you're getting is a well built, high quality materials, and a work horse of a subwoofer. I have a set of the 12's and a set of the 10's and they both are equally impressive. Biggest suggestion that I can give you, is allow them time to be worn in, they are stiff AF when you get them. As they warm and flex, they get better. I'm running the 2 10s with dual 2 ohm vc's at a combined 2 ohm load to the amp. Running a RD.1500.1 JL Audio amp and these subs eat every watt and can take way more. The 10s are in a custom built box under the back seats, box is tuned (ported) to 32hz. My 12s are each powered by a Harmony Audio 1500/1, and they could easily run way more power. Wired to a 1 ohm load each, and in a custom box built to Harmonys air space requirements. ... show more

Replaced SKAR DDX-10 with this harmony C-10 and it was the right choice
Size: 2 Ohm Style: Single Pack
I replaced a SKAR DDX-10 with this harmony carbon 10 and it was the right decision to make for sure, the SKAR hit hard but the sound quality was poop but SPL was great. So I put this one in and crossed my fingers lol AFTER PROPER BREAK-IN STAGE was done man this subwoofer out performs SKAR all day. The SPL is great but the sound quality is 100 times better. Everyone who has heard my system tells me there is a night and day difference between the 2. Sad part is I am using a SKAR amplifier and harmony subwoofer sound better with this amp then skar's own subwoofers lol ... show more

Great sub.
Size: 2 Ohm Style: Single Pack
Sounds great, hits really hard in my full size Yukon. Super heavy. I had two 12" xplode subs in a dual bandpass box before and they were nowhere near as loud as this single 10 in a sealed enclosure. Get em now before the price goes up. Only thing that sucks is the carbon fiber in person don't look like it does in the listing... ... show more
