Well, the Spicas have been set up. Rev, Anders - the Ikea stands were tested for about 30 seconds then discarded (for this app, will store them away as they may come in handy for future speaker scenarios). The Spica servo sub sub came to life - all 70 watts and 8 inches of it - after replacing a fuse. Used a pair of 30 inch Sanus stands (what a monumental piece of crap those stands are, I am going to write a review on them on Amazon), but they proved too tall, so I quickly introduced them to my radial saw and lopped off 4 inches to get them to 26", which works. Imaging is good and gets great and better as you tweak position and toe-in. The sub is very musical (definitely not meant for home theater applications) and supplements the TC-50s very well. I am tempted to get the Sunfire Truesub in the mix as a sub-subwoofer - maybe I will try that later tonight. My room is a small spare bedroom, so I do not need a whole lot of power to get reasonable volumes. They sound great. After Ander's warning and a general lack of desire to search for or buy replacement woofers, I will refrain from flooring them (unless forced by some liquid courage). So the verdict is - they are worthy replacements for the Mirage 890is (I may change my mind in six months and bring the Mirages back in though - as Tom knows i have component attention deficit disorder - also: a pair of low-priced Martin Logans may put the Spicas in peril vey quickly).
Cheers,
OBG
