Was looking for a subwoofer that would fit in the TV bench. Fell for this when others in the same format saw little plastiga out and not as solid. Run the base with a pair of Dali Zensor 5 and am very satisfied. Run the crossover frequency quite low when it just will complement Dali speakers in the lower register. Does the gateway back to the wall, removing the back cover of the TV bench so I have about 20 cm to the wall. The base is best suited for music with "round" and smooth base because of basreflexlösningen. It does not have the same speed as a sealed enclosure. There are better basses for 4000kr, but if you like me do not want a box visible so this option is very good.
