Question: What type of box would be better for these speakers, ported or sealed??
Document: Received item as advertised. These speakers work great and have a great deep base. Put these speaker in my sons Dodge truck in a box that had some cheap speakers that had no base. These worked much better.
Great price for a couple of subs deal, got them just in time for the weekend and had to upgrade my amp to a Brutus 1200.1D amp with a sealed enclosure but I would like to go ported instead to see how much of a difference they make in sound.
These subs are great, they handle very good, very sensitive if you like music clean and no distortion, I got em in a sealed box 1.75 Cubic feet and they hit hard... bass is deep and loud, can be too much sometimes but i think i may try these with ported box,, or a smaller sealed box.
This pair of 12 inch kenwoods is literally shaking my car apart. I barely fit them in the trunk of my 67 mustang. I put them in a sealed box, which is about 1.5 cubic feet. I currently have em hooked to a 650 watt amp mono. This amp gives them plenty of power, but you could easily add a 1000 watt amp and still do just fine. All hooked up with 8 gauge power cable. These speakers are excellent quality.
I got this speaker because of there price . (2) for $60. I use a sealed box & theses subs pound hard. They have a nice clean loud bass. I put these in my wife's car. Paired them w/ a older Excelon 1600 Watt class D AMP. I'm vary impressed. Kenwood did an excellent job on these subs.My wife & I have Kenwood everything in our cars, same decks same 4x amp, front & rear speakers. (Subs & sub amps are diff.
I started with a boss R1100M amp and the mtx terminator 12 package, both were horrible and provided very little bass. After being frustrated. i decided to order these, stick them in a sealed box, and pair them with a Belva bb2000D amp, and boy do they slam! i have them in the back of a 2000 ford crown victoria and they make my trunk flex from the amazing bass, the subs are great and i would recommenced them to any one of my friends.
Now, put them in a ported enclosure, and they'll probably tear your car apart.Bottom line: Great subs, and for the price?... I don't want Type R's or JL W-whatevers. They make your drive more enjoyable, and are more than worth the purchase price. **UPDATE:I decided to build a ported enclosure for a single 3013. It's still awesome. Hits every low, and takes up half the space! Just buy them.
Have these hooked to a kenwood 9105d amp and they hit hard. I have them in a 1.27cuft sealed enclosure. They  recommend .75 - 1.75 cuft sealed and around 2.0 for ported per sub. I noticed these have a pretty smooth response curve all the way up to my x-point of 80hz. They have a real tight clean sound. They also have a vented pole piece and vents on the side of the coil. Couldn't pass up this offer of two for $60.
Ive had medium line of jl audio 12s in the past I got these cause i was thinking they would be around same quality. I was wrong they are better these things hit alot harder with the right amp setup these things slam.
(The boom is very good, especially for how shallow it is. I bet the regular depth ones can boom even better.) A different friend had some MTX's, and they were about the same as the JL's. Anyway, what I would HIGHLY recommend, is get 1 Kenwood, and then one other brand sub woofer. Just make sure it'll fit wattage and such. You'll get the best of both worlds.
Answer: ported gives you really loud bass, but sealed give you that rumble in your seat. I like sealed better but they are both good, I also heard that sealed can kill your sub faster than ported.
