I hope that someone on this forum can offer some advice. I purchased many PZC's and Roomtunes and had them shipped to my home in the Netherlands. I have owned these devices for a couple of years now and I have quickly learned that, in complete opposition to the designer Michael Green's opinion, these products are completely ineffectual in resolving low frequency issues within my room. I have included photographs of their construction with the hope that there may be someone on this forum that can help me modify these devices to better control the peaks and nulls with in the low frequency band of my listening room.Photo 1 shows the inside of a PZC or RoomTune;

Photo 3 shows the so called tuning bolt which applies pressure to the faceplate and a wooden slat at the front of the frame:
http://www.htforum.nl/yabbse/index.php?action=dlattach;topic=47451.0;attach=32148;imageI invested a lot of money in the equipment built by this company and after many attempts to get their assistance in properly implementing their components I was left with unanswered questions and poor excuses as to why their equipment wasn't working the way they said it would.
Has anyone else had a similar experience with this company or can anyone offer advice on how to modify these products to get them to work better?
Many thanks in advance for your kind replies.
Roy.
