I spent about 90 minutes last night searching the Internet for speaker stands to give my son. Try using Google to conduct a search, using the subject "speaker stands". I found about 20 listings, many of them selling both steel and wood stands that would meet your needs.
Speaker Stand Recommendation
Looking for recommendations for speaker stands. Would need them to be relatively tall, say from 28 to 32 inches. I have seen stands with puny little platform that the speakers sit on and would like to see if there is anything with a larger, solid platform for the speaker. Dimensions for speaker are about 9x11. Thanks. Recommendations on where to get such a product also appreciated.
