Kicker 12" L7 ported box?

Question

I am planning to have a custom ported box built for my 2 12" kicker l7 this weekend. I saw this box on eBay let me know what you think.

I might have it built exactly like that one. The problem is it only has one chamber and one vent for both. Do you think this will be a good box? I want my l7 to be loud and boomy. The dimensions will fit perfectly inside my 01 accord trunk. I am open to any suggestions. Let me know what you think. Thanks in advance.

I don't see why they would sound bad in such a large enclosure. Kicker recommends many different enclosure options that you can put those subs into. The largest one is up to 3.25 cubic feet!!! And that is for 1 sub. I think that enclosure would probably be an ok one. I couldn't say for sure without checking it on some enclosure building software. From what i've seen from recommended enclosure sizes from kicker that is not too bad.

The only thing that I would say to look at is the port tuning frequency. If you are looking into more SPL and a boomy sound then that is kind of a low tuning frequency. Usually if you are looking for SPL you will have a higher tuning frequency. With a lower tuning frequency i would say that enclosure is built for more SQ then SPL. That is not to say that it wouldn't be loud though.

Putting two subs in a single chambered enclosure is pretty common for vented enclosures. It take up less space then an enclosure that has dividers in it. It also allows you to have a single port and not have 2 seperate ports. This will also help to save space. The sound will most likely not be effected much by having a single chamber. The downside is that if you ever blow a sub or if one of your subs is not performing well then you will risk damaging your other sub.

One suggestion I would give you is to make sure the vent has a big enough cross sectional area. If it is too small you will have port noise. From the picture it looked big enough to be ok. If you really wanted to make sure that the enclosure will look good then you can run it through a program like WinISD which let you see exactly how the subs would perform in an enclosure like that. Also, with an enclosure that big it is a good idea to use bracing to prevent flexing in the wood.

Good Luck!!!!

Kicker L7 woofers are one of the best on the market, but it doesnt matter how good a woofer is it can still be made to sound like **** and pop. So when you have your box built get the little booklet that comes with the woofers and have the person building the box build the ported box to the specs of the manufacturer, because if they build the ports to big then the woofer gets to much air and it will pop and if they build them to small it wont get enough and it will sound muffled. When they build the box weather it is sealed or ported the box will look small because kicker L7 are made to give you the maximum amount of base with less airspace. I have those woofers and I have them in a sealed box and they sound ******* nice and they ******* pond. I say dont waiste your money on ported at all just get a regular sealed box and spend that extra money on a really good amp because that will make the biggest diference in sound and power

Along with stone, mud and animal parts, wood was one of the first materials worked by early humans. Microwear analysis of the Mousterian stone tools used by the Neanderthals show that many were used to work wood. The development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials.

Answer 9

those are fairly expensive subs. if you're not an experienced box builder, i would buy a good prefab box. i see all kind of crappy boxes people TRIED to build. some are probably held together with duct tape and zip ties.

Answer 10

Bad idea. The subs will not perform well in such a large chamber.
