Push-pull LF driver for up to 250Hz

[AdamZuf]

Hello guys,

I want to have a 2 driver, top quality, push-pull floorstanding cabinet that can be crossed as high as ~250-300Hz, 2nd order at least.
Should extend to <35Hz at least -3dB.
The box can be as large as 110 liters (55 per driver).
I can have up to 12" drivers (rotated, for a slim box), but less diameter would be nice and open design possibilities, however not crucial.
Don't want to go more then $200 per driver.
Sensitivity is better then power handling, as always.

Should do well with all types of music except classical. I prefer a fast and very dynamic sound then soft and laid-back.
It's not intended for HT.
My living room is medium size.

The drivers will be at 90cm height, if that's of any concern.


Any good suggestions?

Thanks
Adam
