Yet another recommendation for a PHY based speaker. If you want true bass down to 38, you probably want to use a speaker with a 12" PHY. The Tonian Classic 12 fits the bill. There are other very good PHY based brands but I've always been drawn to Tony's speakers and the way he integrates the PHY driver with his modified supertweeter. PHY speakers are not cheap but I find they are worth the additional cost.
