OK all you Infinity RS 1A/1B Beta speaker owners..

I put in a pre order with graz,waiting to here back.Don,t know if they will work in conjunction with the other emim drivers that opperate at diferent frequency might blend right.As you know the RS1bs are a point source system most think it is a line source system.Only 1 emim on each side gets to do most of the work the other 12 emims work at a lower frequency to blend with the bass towers.They are starting to sound prety good,but I think my 3.6 maggies are better.With the maggies I did use infinity RS1b bass towers and the crossover and only the mid/high section of the maggies.They have a much more defined soundstage that goes wall to wall and has lots of depth.I also have about 10 years of tuning them up with cables (speaker & interconect)Amps.The amps don,t work at all with the infinitys.So I have not given up yet I will tune them for a while if I can,t fix the shortcomings I am thinking of going to the maggie 20.1s With the infinity bass towers.I am lucky to have collected 3 sets of bass towers and 4 crossovers over the years. 2 sets have sequencal serial numbers.I guess I rambled on to answer your question yes.

The IIb's are the same way, a point source, just with less EMIMs. The Center EMIM is run twice as loud as the other two above and below it.

Here is a link to a thread with posts by a guy who replaced his RS1B EMIMs one pair at a time starting with the high ones - he thought they blended well...
