They are without a doubt in my mind, the best subs available. There are a couple of subs that haven't been released that could be close, but until they are released, nothing can touch the titaniums. Not sure where to get the titaniums online, but you could go to stryke.com. They sell the same sub without the eclipse name. You could try them out, they might have a good price. Keep in mind that they are going to run you in excess of 800.00 for a 15.
