    Box for 2 12 L7. Need help bad!!!!

    Ive tried two different boxes for these subs and I know these sub can do way more damage!!!!! Ive tried these 2 boxes:

    32w x 15h x 24d 1 2in port that goes back 18 5/8 This box was a monster but they told to do a 2nd port and it would do even better.

    34w x 15h x 24d 2 2in ports that goes back 18 5/8 This the sorry *** box that they told me to build and was worse!!!!!!! When low bass hit, the subs barely move!!!! I decided to put polyfill behind 1 of the subs and that one outdid the the other. Then, I plugged the port up on the other sub and that one outdid the polyfill. I got more sound from doing this but it still *****!!!!! The bass is not solid @ all.

    Can someone help me please???????? Thanx

    2 2in ports? I'd have more port area than that for a single 10.

    Re: Box for 2 12 L7. Need help bad!!!!

    Everytime I do a bigger port I would get 1 or the other. I got high bass but, when the low end hit, the subs bottom out. I had 1 2inch port that out did all the boxes Ive had. so, the local shop told me to add another port to the box and I would hit twice a hard. I figured out what the prob was, When I added the port, I added 2 inches to the port and didnt take the inches away from another section of the box. So im going to take 2 inches off the height. Will that help????

    Have you looked the www.kicker.com website? I have almost always DL'ed the specs or talked to there techs on the phone and told them my situation. They have never steared me wrong! Noone knows there stuff better then them! As for the L7 12's I have used the recommended specs from the site for the large ported enclosure and everytime sound beautiful!
