I bought a pair of Infinity RS3b's new back I think in 1978. They were really nice speakers at the time. Over the years the foam around the drivers and front baffle rotted and I refoamed the drivers. The baffle I replaced with carpet That I cutted out and glued on. But the sound was OK until I started to changed the crossover, connectors and internal wiring to a much higher grade. Mundorfs, V-Caps, Duelund resisters, flat ribbon inductors, Cardas internal wirings and speaker posts, and took out those music destroying internal fuses and tweeter midrange controls. What a difference in sound!! The sound is organic and highly transparent. It's well worth the time and expense to do the mods. It is a uniquely sounding speaker that is very musical.
I am trying to decide between a vintage pair of infinity rs iiia and triangle borea BR08. I will have them in a large open living room and I listen to rock, pop, and country music. I will be pushing them with a pro-ject audio rs amp. The infinities are legendary speakers but obviously are older and may need to be refoamed. The BR08‘s are new. I will save a few hundred going with the infinities. Is there a big leap in speaker quality between the two? Are vintage better made? Any input would be greatly appreciated. I should also say I am not looking to blow the doors off the house. I am looking for great sounding and detailed sound. I am open to any other suggestions. There is no particular reason for these two other than they are in my price range of around 1k and they are available in my area.
the room they will be in is 20x30 with a 10’ ceiling. And the specs on my amp are as follows.
