CHeck your polarity. Make sure both cones are pushing out together, then pulling in together. If they are opposite, they will fight each other and give you the response you described.

I have problems both in and outdoor.

I found a suggestion about installing horn subwoofers, here is it: http://www.soundlightcrew.hu/hangfaltervek/rutsevaria.jpg

Not so complicated, I have 2 so I installed as the first pictures shows.

My problem: There is almost nothing bass "kick" in the middle section, I have painted a very poor about how I hear it.

I also tried the subs installing vertically, it's the same.

Here is my masterpiece: http://img811.imageshack.us/img811/1913/subgo.jpg

Red is where I hear nothing bass, at green it kicks very hard.

By the way the subs are 21", 600w but I think that doesn't really matter. The inside of the box is not so complicated, its something similar to what I painted.

Does anybody have idea how should I make it?

Try unplugging one of the subs to see if it gets better. Your drawing suggests that the subs are out of polarity with each other.

I know they're different, but the Martin WSX sub puts the mouths of the subs together (their driver is not exposed like yours).  Have you tried placing the subs as such?  Also agree with driver polarity.

Thanks for your help very much (I don't know how I didn't find out polarity...)

It's interesting (for me) that now the polarity of the subs are different, and now the sound is very good in the middle. Is it normal? I mean, the polarity is normal at one sub, and changed at the other.

Thanks

It is unclear what you mean by that statement. If the output of each sub is in polarity with regards to the other one, they will sum together and be louder than a single sub. If the output of each sub is out of polarity with regards to the other one, they will still sum together, but be less bass than a single sub.

You need to check your wiring from mixer output to subwoofer input to determine that it is all wired correctly to maintain the same polarity throughout the signal chain. If you have had to change the polarity to make the subs add together positively rather than negatively there is something wired wrong.
