Thanks, Don!
I really appreciate that info!
I had picked up some of the current BIC America's rTr branded speaker systems for the HT. Pretty decent speakers. Since I went with all Yamaha speaker systems for the HT, I've given one pair of the rTr 123 to my bro & sis-in-law (along with a Yamaha CR-1040, and Sansui cassette deck and a Sony cdplayer), and right now a pair stacked on the orig Advent, driven by my Nikko NR-1015. Both my other pairs of Advent's need new foams.
