If that Eclipse is a 2" coil, my mistake as I thought last I read it was a 3" and the power ratting is very high for a 2". Anyway, comparing initial price is one of the major issues with car audio. So many people fail to think about over all cost, instead of just initial cost. Also, most everyone fails to think about the differences in brands that makes these products. Example: Companies such as JL, ID and Eclipse often get compared to our sub woofers as they only know the big names so the think they need a direct price comparison. The major fault with that is, those brands are building their drivers extremely cheaply overseas, often times using the cheapest possible parts. This is because they have a great deal of overhead, advertising, promotions, sponsorships, etc. etc. etc. Included with all of that overhead and so on, is dialed in brand name premium. Now, SSA consists of two people that have the sub woofers, hand built with the best parts, here in the USA, with no brand name premium. What that means is, for the end customer, the value, quality and performance of and SSA sub woofer unquestionably trumps a RF or JL etc. What that means to SSA the company is, we have no where near the mark up or profit that these other brands do that go overseas. So excellent end product for the customer, no 2010 show vehicles in our drive ways, or bikini girls at our demo booth. Fairly simple distinction, but the continuing issue is that most customers don't take 15 seconds to process the differences on the grand scheme.
