I recently purchased a pair of Paradigm Signature S-4 speakers (22" in height). I did not splurge the extra $300 for the Paradigm J-23 stands. I figured I could buy more attractive stands for less money off the internet. Does anyone know the dimensions (height, etc.) of the J-23s? I understand that the tweeter should be at ear level. Is that correct? Also, know of any good websites for inexpensive stands?
