| planer transducers...advice? Ive been looking at some planers, bohlender graebeners in particular from parts express. I did not realize that planers existed that could play such low frequencies. approaching 150 hz on the low end! has anybodt heard or used these? Im suddenly very interested in these. unfortunately VERY expensive... $700 for the six footer, $500 for the four footer. Ive never used any type of planer, ribbon, etc. Id like to hear anybodys opinions |
