As i said earlier the 950s were upgraded last year in line with the the latest versions of the s150s and the new 750s,. They all now have the same badges, drive units, but the crossovers were also upgraded along with the speaker terminals so is a substantial upgrade. So the newly upgraded 950s sound different to the original 950s that have the pro tweeter and the new 750s sound different than the original 750s also. The 950t Tripole surround speakers were not upgraded, so if you want an all Satin finish and want the newly upgraded 950s then the 150ts will match the 950s Satin finish. I had the upgraded LCR in room versions of the 950s and the current 150ts along with a V12 subwoofer in my living room and the timbre matching and blend was great.My understanding is the current 750’s use the same tweeter and woofers as the 150’s. I’m not sure if the 950’s were updated in the time that i’ve owned mine. (Mine are 3 years old) The 950’s and 750’s measure slightly different in the highs. I’ll attach graphs.
The cabinet of the 950’s is definitely nicer. The tweeter is different. No angled tweeters in the 950’s.
the first graph is the measured response of the 950’s (green graph) and the second is the 750.
