Dave, We (I) realize this is a bit of wishful thinking and may take a long time to materialize, IF it ever does. I have been working on a project for a new-to-market product that is now going on 2 years. We had a very positive field test and thought we had hit it out of the park, until we encountered a hiccup. Fortunately the customer is working with us to iron out the wrinkles, but it could take some time.
We know you will do your best to explore the best options in the end. If I have to "get by" with the standard woofer in my Sierra-2's then I will have to suck it up!
