NEO Dan , bjorno ,
First of all I am sorry for my bad english...
I am planning to buy Kicker 15L7D2 tomorrow and I need your precious advices . I have to go with Car Sub because I could not find HT Sub Driver in my town.
Tapped Horn Loaded design is too big for my room and I think that Kicker Square drivers playing agressively if you infront of the driver.
Could you please help me to find best possible 35 hz Bandpass design for this sub? Maybe I can get better result than sealed or ported designs for SQ .

This box takes very little floor space, how much smaller would you need the box to be?

This subwoofer is longer than my floorstanders and this will be located in the living room .
I am thinking 20x20x40 inches maximum .
amplifier will be NU3000DSP Behringer Bridged ...

Agree with Dan..A BP box would at least occupy >60 x 60 x 60 cm^2 floor space..See picture:

IMO,I think you should consider an optimal closed box (Small footprint +f-3dB=~39 Hz) instead and use EQ for BW down to 35 Hz.

With the nu3000dsp I would build two enclosures loaded with the D4 drivers.

I can think of it.

I need an honest advice if you think the tapped horn is the best design I will try to make this box...

This design is more efficient and has better response and power handling than the sealed box. Use the 2008 or 2011 S15L74 driver with the coils wired in series to make an 8 ohm speaker. This configuration will allow you to run up to two subwoofers on your bridged amp and give you >1000w each.
