Anybody tried from Thomann "the box pro Achat 110 M"

If, this: ---> http://www.thomann.de/at/the_box_pro_achat_112_ma.htm

The low frequencies start at the 10 inch box only at 70Hz, which makes for the bass range may be problems. Therefore, the 12 inch box of this series is likely to be more appropriate. Still unbeatable http://www.thomann.de/yamaha_dxr_10.htm
Better save more money and buy something professional? Just my thoughts....
