Many years ago Infinity stopped the production of the legendary 4 Ohm 902-3075 & 902-5793 Polydomes. The midrange driver was used in the series: Infinity Kappa 5/6/6.x/7/7.x/8/8.x/9/9.x
There are 2 different possibilities for repair. Lovers of originality will choose the option to retrofit the original driver with a new diaphragm. The original Polydome has a bend in the middle frequency range, but still has a very silky and soft sound, which makes voices sound authentic and emotional.
Vintage Infinity: Classics from the 80s and 90s worth preserving!
