My name is John Allen, I bought my TC-50's in the mid-80s, and later added the factory sub. My friends would come over for listening sessions with a handful of records and we would listen for hours. The speakers had a phenomenal ability to cast a big stage with clarity and their ability to image is legendary. While my system cost much less than others in the listening group, the sound it produced wasn't in the budget category.
Sad to say, but the albums just haven't been spinning as much these past few years and the Spicas became neglected. One of my teenagers wanted to listen one of albums, so I dusted things off and went to listen. That's when I discovered that my cats (yikes!) had taken their toll on the drivers. I was disheartened, these speakers have been the source of much enjoyment and I felt I needed to put them back in order. I had squirreled away spare tweeter and woofer, but sadly, I needed two of each to get back in the grove and so I began trying to find replacements.
That put me on an unexpected quest for information about these speakers and all things Spica. I launched this website in 2006 and added content as I could find it, so that others can benefit from my journey.
I participate on the Spica User Forum and I must acknowledge the people of that community for the information they have shared. I also owe a big "thank you" to the people who have contacted me directly to share stories, photos, and manuals. My greatest thanks of course goes to Spica designer John Bau, whose Spica TC-50 was the genesis for this site and who surprised me one day with an email with schematics attached! I don't know if that could be considered an endorsement, but I do feel it validates my efforts and has provided a means to fill in some of the missing pieces.
If you have questions that aren’t covered here, please visit the Spica User group. There is a large community of Audio folks there and your questions will grow the base of information and benefit the larger community. -- John A.
