Just Purchased Infinity RS2B / RSIIb owned RS 2.5


FYI Infinity Fans:
I have lusted after some RS2bs for 20 years after loveing my 2.5s. I thought the 2bs would fill in the middle and keep all of the strengths of the 2.5s. In reading the manual, I was unaware that the 2bs had a bass equilizer (not crossover) that was NOT optional. The bass equilizer has been lost. I hooked up my VTL compact 100s with several preamps & the sound was mud in the bass and boring in the emims/emits. One of the emits is even covered 50 percent, the top one in the front. These 2bs sound like monster cable . . . go figure. Monster cable was used in the speakers. Also, it turns out that ONLY the middle emim is hooked to the midrange control. The middle emim is the only one that sounds like the emims in the 2.5...they are running full out. The top and bottom emim are subdued and they are trying to mimic a good dome midrange....yes the lower vocals are better but who cares?? I have lost the magic of the emims. I have had some Infinity Sigmas in my room and one super emim did a better job than these three emims. Last night I hooked up a couple of transitor amps and the sound was MUCH improved... remember what older monster cable did to good solid state stuff? in the 80s. I guess I'm going to stay with threshold but I own several good tube amps that I love to hear the imaging etc etc. I might be nuts but the improvement I have gained with Kimber Kable 4TC and Audioquest jaguar interconects is lost in the old monster cable wire?? I am probably being to hard on these speakers, but I remember a german saying the 4.5s were the best of that vintage. How are the emims controled in the RS1bs?? are they all hooked to the crossover controls?? To be continued. Thanks for reading. Larry

I wish I'd never sold my 2B's!! You're right Speedy, I could never get those damn 4.5's to image!(and they had plenty of breathing room too!)

After listening to the two emims in the 2.5s for 20 years, it is taking time to adapt to the two outer emims playing lower frequency but I am getting use to it. Much better on piano and vocals. The low end is my big problem. If I play at lower volumes the bass is the best I have ever heard, but when I turn it up it definitly gets boomy in my room with the built in shelves and cabnets next to the fireplace...The speakers are half in front of tile on fireplace and half in front of cabnets..two feet away. I opened the cabnets up to put up some stereo stuff in and went back to listen before shutting the doors.....Big difference in bass, total boomy mudd. I am going to take the speakers to a friends house with a solid wall behind them. I think infinity knew the speakers could get boomy and thats why they made the comments in the manual. OK I HAVE A BIG QUESTION. Can anyone tell from the circuit diagram of the bass eq if in the 12 o'clock position it is neutral and not affecting the lower frequencies??? Thanks Larry.
I sent him an email and Bill answered at 5:30 am!!!!
FYI Bill Watkins did the refoaming.

Dear Larry,

The manual is correct of course. If they're very boomy, it could mean that they were incorrectly refoamed, using the incorrect-tension material. The other reason would be too much cabinet stuffing, or damping added to the cabinet walls. The EQ was made by the good people at Monolithic Sound in CA. It's possible that they may still have an EQ available, though I doubt it. There's a company called DB Systems (location unknown) that can make custom EQ/crossovers. You may want to Google them.

The 2b's are one of the most musical of all Infiniti's, and one of my favorites.

Enjoy the weekend!

Cheers,
Bill
