Played 2 of these in my car and i instantly fell in love. Left my wife because this is all i need. Sub is so loud my ex wife still hears it 2 states away. It not only sets off all the car alarms in the parking lot but if i park close enough to my bosses car, he doesn't have any windows left! 10/10 amazing sub must buy.
Not quite DD Audio.

Not quite DD Audio, but wow! For the savings these sub's are awesome. Big difference in cone area versus their smaller sub's because of the cones depth, which results in a big difference in sound.

I got 2 of these 18's. When they came in the mail the first thing i thought when i seen them is "im gonna need a bigger amp" but i hooked up to my kicker 1800 just to hear them, and oh hell did they hit hard. Way louder than my 4 15" mtx 8000's on over 6000 watts. That little amp jammed the hell out of these monsters. They handle the power yet play loud as hell on low watts. Love'm never go back!

This sub will pound really hard like I pound my girls but I have 1 of these and my friend can hear me form about 2 miles away. And this almost broke my windshield and now my nipples get hard from the cold air.

I got 50 of these and my friend could hear me 15 miles away, I put 50 of these in my bus and got a bunch of amps and it's alright bass.
The HDC series isn't just some off the shelf woofer designed in the virtual world. It is the product of over two years and hundreds of hours of real world research and development. Many of the HDC's features are only found on woofers costing twice the price. When compared to our competition the HDC series woofers have more cooling, more throw, more motor force, and stronger cones. These woofers work great in everyday street beating or all out gut wrenching SPL builds. We have spared no expense to give you the best subwoofer value on the market today.
The HDC comes with your choice of three different high performance voice coils. For the street beaters we offer a four layer, round wound, dual 1ohm or dual 2ohm copper coil. If you're in need of a straight SPL woofer we offer an 8 layer, flat wound, dual 1ohm Aluminum coil. To increase our coils thermal handling we use the highest temperature adhesives available to us.
Suspension systems are generally a weak link in a woofer design, and often the primary reason for woofer failure. Over time, especially in high power applications, suspension begins to sag and as a consequence it can no longer control the voice coils movement. This generally results in a torn suspension or smashed voice coil. To avoid this we use a multiple spider configuration engineered to maintain rigidity over extended periods of heavy use. We also hand glue our triple joints to allow for better glue penetration and saturation of the high stress areas.
HDC DIRECT CONNECT LEAD WIRES
High excursion subwoofers require a lead wire system that doesn't flop all over the place or break. We use the direct connect system (no terminals) because it works the best. With our direct connect system you get no annoying lead slap noise, no rips or holes burnt in the spiders, and no flimsy lead-in wires.
