Hab einen Kolleg aus DE angefragt. Kennt sich mit Car HiFi gut aus, und hat mir auch die Anlage von meinem EX BB6 vorgeschlagen und war voll zufrieden damit . Hab auch noch mit dem Verkäufer über das Thema diskutiert und er meinte es gäbe in seiner Preisklasse nix besseres... 
Ich persönlich hab keinen blossen Schimmer über Car HiFi...

Product Description
A brand new concept in enclosure design - a totally acoustic friendly environment has been created for the FLI woofer - a large curved top is formed and tapered down to its base, this curved enclosure offers a perfect acoustic channel which automatically deletes enclosure resonance. The baffle boards at each end of the enclosure are angled forming a double wedge design. The double wedge offers increased pressures inside the tunnel maximising bass output. The enclosure is designed to work with a single woofer working against the opposite wedge or dual woofers firing into each other further increasing enclosure pressure and cone control with significantly increased output. Overall the new FLI design offers a very compact bass system that is capable of generating tighter, deeper, bigger bass than conventional enclosure designs.
