? concerning dual ports for a single sub

W00t! I thought that was right....
But, wasn't sure, Wine gives you a bad feeling the next morning or well afternoon....

I'll second that, I was dizzy and I swear the walls were moving.

It doesn't give you a very good buzz either.... I had the crappy feeling of the buzz but not the good feeling... I was very unhappy.....

Now Jeger on the other hand.... Makes you fall at a party and not even remember it.... But you know you did fall because of the big bruise on your hip.... *Speaking from experience*

i have a box similar to what you are talking about and i think it looks nice. It's 38 wide x 14 tall x 14.5 deep. here's a pic.

how q sound at 30? is 2.2 to small in your opinion, would u like to have lets say 2.5?

Mike

also it doesn't look bad either

38.5 wide x 14.5 height x 16.5 width - .75" of mdf you have a good: 4.175cuft to play with. so if you go with a 2.5cuft enclosure tune to 32Hz with 2 ports each port being 13" x 1.5" x 37.23" that will give you 39sqin of port area per port. more then enough to keep port noise down. and thats an even smaller enclosure 3.727cuft. so you still have room for sub displacement and lots of bracing to make the enclosure super solid.

I have a Q at 30 hz in a 2.5cube box and I absolutely love the low end. I'm guessing it could be louder, but I would rather have it quieter up in the higher frequencies and dominate the lows.

well here the plan, i have a single 12" fi q, and ill be tuning around 28 - 30 hz. I have a big trunk car, and really want to take advantage of its width. so i was going for dimensions like 38.5 wide x 14.5 height x 15.5 - 16.5 width. now i really want to use this big width but i think it would look akward having a port on only one side and the sub far away. i was thinking of having my fi q centered and run 2 L ports to the front sides of the box
Something like you see with dual sub setups

Now here the ?

How would i go about figuring out how much width and length and area i would need of the port, i have single port plans of a 2.5 cu ft. box @ 30hz after displacements and stuff and i have a port area of 40, port length of 39 and port width of 3.25, how would i turn this into a dual L port design, im pretty sure you dont just divide by 2 .

would a maze port actually be better then an L port for going for a dual port on a single sub?

Help me out and guide me, if one of you guys wants to work on one, use the dimensions above

Mike-

tuning this isnt a problem for me duder.

I've done them before, and actually prefer them for single sub setups

well i wanted to get my plans, so you didnt have to use ur time , seeing how ur already doing alot, it one thing out of the way.

But if u insist and its your speciality pimp, sending pm right now.
