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

The part worked like a charm. Easy to install, and fit into the existing slot like a glove. The sound performance is just like the original.

Bought 4 Infinity 3" Fabric Dome, 6 Ohm, M-330s. Replacing worn out mids in a 4-unit Kappa 7 installation. Mounting screw hole positions did not exactly match the originals and had to be drilled out a bit to fit. Once all was assembled, testing showed the new mids were much more efficient than the originals and mid range sound was too strong. The system included two 1/3-octave equalizers and with pink noise and a calibrated spectrum analyzer the combo speakers/and room were re-balanced just fine. It's great to have the amazing system of 4 Kappa 7 speakers working properly again!
