It is coupled with a 550 Ashdown little bastard (handmade 50 copies).
The bass is really deep and rich with more than 15 leading shoot. The point of view of power is more than enough.
All bass sound that rose above hell.
I leave it in my studio because this box is 50 kg and difficult to move alone considering its size. For concerts, I use a 4x10 Trace Elliot and Ashdown AD-600.
The price / quality ratio on clearance (259 euros) is unbeatable.
