Infinity Kappa 9.1 Series II 4-ways speakers. These speakers have the extended switches at the back (see P.8 of the manual, weblink below), allows the bass response to go down to 25 Hz, or 29 Hz at normal position. I paired the speakers with Yamaha M85, the speakers filled the room with moving air and sound, it was dynamic and fuller when compared with PSB T8. Conditions are Good consider these are decades old vintage. The photos represents the general current conditons. The grilles (not shown in photos) are good except the fibric will need to be replaced. All parts works. Sell them because they take up too much space. Manual: http://www.infinity-classics.de/technik/manuals/Kappa-xII-om.pdf Local pick up or you can arrange the shipping. Will help to load when pickup. https://youtu.be/ljk8s4hB8Ho https://youtu.be/7HexzAL3BJw https://youtu.be/4EbeynlnCu0 https://youtu.be/IQjCmrqBX3M https://youtu.be/IQjCmrqBX3M
