It's been a year since I have this pair of bbs!
They are powered by an amp AudioPhony CX850:
2x425w RMS into 8ohms for pregnant are given 265w RMS.
The amp pushed back, they do not budge!
This is an excellent quality price. It is robust, reliable, and they sound ultra clean! (For a more rock rather see in Wharfedale).
Also they are not trs heavy (but rather cumbersome.
It's a bit lightweight for a room sound to FTEs (prvoir another bass amp and 2, and thus a small filter!) But they are perfect pourjouer in a bar, or in return for sc only in a large room.
If I re c'tait Do not hesitate one second!
