I think your pricing is appropriate, even slightly low, from what I see. I saw plenty in the sold section at HiFiShark to give me an idea. Some are higher for what you are selling, some slightly lower. When I search HiFiShark, I use broader terms and then look through the individual ads. For what you have, I just searched Rythmik F12. You have to look for those that have the A 370 amp in the ads themselves. You also need to know which driver is in them .There is a standard aluminum cone (either silver or black) or an optional GR Research paper cone driver. Not having boxes hurts because it shrinks the pool of buyers, but you price is very fair IMO.
