Hello Simply Speakers Team ! Thank you for the quick and competent delivery. I have a pair of Infinity Kappa’s and my Mid-Dome’s were damaged. I took the old domes out and it was very easy to put in the replacements. Now my Kappa's Sound like new, maybe even a bit more detailed then before ;-)

Good price and sound quality
With my Infinity Kappa 7 speakers still having excellent sound, the affordable replacement of my one damaged Polydome speaker has restored them to their original sound quality.

I studied to find the best solution for my kappa 8 speakers . I had refoamed the bass speakers 4 years earlier and I considered reconing and this meant shipping the speakers to a speakertechnicean who can do this . Then I found these speakers for sale that are brandnew. It was very easy to replace the old suckers and used a small nail and hammer to screw the 4 original screws in place . The sound is superb and I hear that the new midrange speakers are doing a great soundjob , probably somewhat better than the originals . I recently bould sewell thick speakerwire and additionally get improvement over the old monster wire I was using . Friends are impressed with the sound of the speakers . My amplifier is a Yamaha DSP-A1 . I recommend those new domespeakers to anyone and don't forget to spend some extra on thicker speakerwire . Enjoy !

Excellent Product
These speakers were shipped very quickly. They are exact replacements in size and sound quality of the original speakers. Replacement was a snap, mounting holes aligned perfectly and resoldering for proper phase was very easy. Very pleased with these speakers and quick service from your company. Thank You!

Speaker works really well. I need to replace the one in the other speaker now as the new one has a brighter sound that the original 30 yr old one

Great Replacements
I’ve owned my Infinity Kappa 82 for 26 years and can’t imagine owning something else. My midrange Kappa Polydome speakers finally succumbed to time and multiple shipments. I wasted devastated until I found these replacements. I soldered them in and and completed my speaker restoration by replacing my woofer foam surrounds, dust cover replacements and the my midrange speaker replacements. My speakers sound as good as when I bought them in Okinawa in 1993. Great replacement for Infinity Kappa 8s!

Sound is awesome. Very good construction. My only criticism is that the terminal connections were on opposite sides (way too close to each other) as per the original design and more clearly marked positive/negative. But like I said, they sound really really GOOD!
