Very nice full tone sourround speaker. The best i ever had.
They work 5.1 with jamo concert 7, (earlyer concert 11) concert 8 center, and a SA sub elektro 100.
IT is not new, but a very nice balancend sound, with a nice onkyo factory.
Sound from 18 hz and up.
The dipol method is working very fine.
Next i want 2 more, going to 7.1.
