The speakers have been in storage for a good year and not used.. I am the second owner and believe the original owner had all drivers redone with factory drivers.. they sound exceptionally clear thru the mid/hi's sector with good soundstage.. good lows too! You will need a good 150w+ to push these babies! The only drawback to this deal is that 1 of the midrange drivers (see pic), the magnet separated from the voice coil (glue let go? fix?) but it sells on ebay for $94.. This is a review I saw online but best to google and read various reviews/specs: In Conclusion: The Infinity Kappa 6.1s are a solid choice for those looking for clear, detailed sound, especially in the mid and high frequencies. However, users who prioritize deep bass or listen at higher volumes may need to consider proper amplification and speaker placement to get the most out of these speakers. Guys... please be serious and not waste my time nor yours.. I will NOT reply to texts nor SCAMS..
