Thanks for the information. I checked the initials on the back and there were indeed two sets on one but only one set on the others. OD, who I assume was the sander, was on both and AS was on the speaker built in 1978, which would suggest that you, indeed, were responsible for at least one of my speakers. Wow!! I get, personally if not in person, to thank someone who had a part in giving me a lot of joy over the years. Thank you very much. The internet is truly an amazing thing - allowing me to connect to someone so intimately responsible for years of listening pleasure. I think I'll try them on the floor again. peace Bryon

HI I was wondering if someone could help me with some information on my Heresys. The serial #s are HBR 62S012 inspected by Jenny Hunt(signature hard to read with my old eyes) and tested by NWBradford and HBR 73T571 inspected by April Conray (maybe) and tested by NWBradford. I bought them as a pair in 1978 I think - might have been 1979-(maybe the experts here can help me with the year of manufacture)and am wondering why the serial #'s vary so much. I know the HBR stands for Heresy Birch Unfinished but the other numbers I am not sure about. Can someone tell me what the year of manufacture was as well as what type drivers they have and the crossover type. Until about six months ago I was using solid state equipment and was becoming dissatisfied with the sound which I found a bit harsh and considered changing speakers. This fall I made the move to tubes - with a Botthead foreplay and Paramour 2A3 monoblocks and it was a match made in Heaven. So much better sound, so smooth and sweet but maybe lacking a bit of life. I've never taken off the backs but lately the diy bug has bitten, and I am thinking of rewiring and recapping the speakers. After all after 24 years oxidation has probably taken its toll. Any suggestions? I remember the literature which came with the Heresys suggested that they be placed in a corner on the floor so the floor would act as a sounding board and improve the bass response. That seemed to work with hardwood floors but I wasn't sure with wall to wall carpet. I succumbed to building risers a few years ago and wonder if that didn't cause some of the deterioration. I would put them on the floor and A-B the placement but they are heavy and my back is bad so I was wondering what others have found and if there is an optimum height for risers if they are beneficial. thanks peace Bryon
