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!

Mr
Hi, Thanks for the pair of 6" Midrange Dome 3" replacement. I have since had them replaced in my Infinity Kappa 7 speakers and the sound is awesome, and of good quality. probably as good as the original. A couple of minor points which you may already know of: 1) The screw holes don't quite line up; and 2) We couldn't directly plug the connectors as the new terminals are significantly smaller than the original ones. So a modification had to be made and the connectors had to be soldered (apologies if I didn't use the correct technical terminology! Regards Cheruvari Vishvanath (Vish)

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!

Replacement for AR/Advent Dome
This midrange unit replaces a single mid-range dome from AR/Advent previously purchased from Simply Speakers. It was damaged during moving. If the AR unit is available I would choose that over the Infinity. The Infinity does quite well at lower midrange but it lacks the presence of the AR unit . This is noticeable when switching from channels at the amp. Some vocals seem to lack emphasis . While the impedance is higher on the Infinity I don't think that is the reason so much as the response at the higher frequencies. However, it does perform acceptably if it is the only choice. I am very pleased with the service from Simply Speakers. I spent my discussions with them on the Woofers I chose and should have spent more time discussing an alternative to the AR unit which was not available at the time.

Beautiful Replacement.
This really knocks it out of the park, you really hit the mark with these. As far as I’m concerned they are as good if not better than the original’s. I ended up using these on my sons kappa 8’s. They really livened up the old Kappas and we think they look Great ! They really sound excellent to us and I’m betting they will really settle in nicely as time goes on. I can’t wait to purchase another pair for my Kappa 9’s. The only downside was one dome was crushed during shipping, I was able to separate it and push the dome back out. Highly Recommended.

Q:
Greetings. I have two questions. The sensitivity rating on this driver (6" Dome Midrange, Infinity 3" Fabric Dome, 6 Ohms, M-330) is 92dB with one watt at one meter, whereas the Infinity Kappa 9's that I own are rated at 89dB. However that rating was for the entire speaker system, not (as far as I know) for the individual driver(s). Is this appropriate? My second question is, if I were to install this fabric dome in one of my two speakers and continue to use the factory polypropylene dome in the other, will the two speakers work well together or could there be a coloring of the sound would make them sound unnatural together? Thanks, David Ryden
Asked by:
David
- 8/29/2015
A:
It is always best to replace these in pairs as they are not exactly like the original Polydomes. The sensitivity rating from Infinity is for your entire cabinet, and the midrange drivers are higher on their own, but the crossover pads them back accordingly so there are no issues using them with the other original components.
