I truly enjoy reading the different internet audio idiots expressing their “wisdom” about what I do.  There is a site out there filed with typical audio white trash and they suddenly developed a desire to criticize my admiration of FM based upon the allegation that FM has limited bandwidth. One idiot proclaimed: “How FM might be good if it never goes lower then 40Hz?”

Well, that certainly requires some commentary from me. First of all am very much convinced that even 40Hz bass is NOT reproduced by great majority audio morons but it is not the point.  The bandwidth of my TU-X1 is from 10Hz and up. The bandwidth of stock Roden-Schwartz receiver is 40Hz but after my modifications it is 2.8Hz. This takes care about the prejudices about receivers.  Mind you that this is true bandwidths that I measured driving modulated sweeps.

Now about the signal. Sure, the FM standard is written from 30Hz but the reality is way not like this. In fact FM that I am getting has MUCH more ULF signal then most of the CDs. Do not forget that I have my ULF channels running by Yamaha B2 and this amp has very high quality and very well calibrated large modulation meters. The B2 sits behind high order crossover (18dB and 24dB) at 20Hz, so by looking at the ULF power amps meters I can absolutely objectively judge about the LF bandwidth of the signal. I can only assure that there is very few CD I’ve ever seen that has as much LF information as FM broadcasts.

I do not insist that FM bass is the best but with all my humility and modesty I truly do not see need to explain to most of the typical ignorant audio idiots the specific of bass reproduction. However, even in quantitative would, the only world that most of audio fools understand, the statement that FM has no bass below 40Hz is absolutely faulty.
