I would love to do an icon. I know that will be a crap ton of bass too, its just hard to guage without ever hearing these woofers or a system much larger then mine actually. Another question....are the icons shipping with the new cone? I just saw in a new build thread, (maybe stafan's?) that they had the look of an xcon. Are they all shipping like that? Also, my amp has a fixed SSF at 28hz. So I will probably tune the box at 28-30hz. but how high could I go before I would run into problems? Those are the prototypes. We are allowing a few people to grab the newer version before their "official release", as we are still awaiting parts for the 10" model. The differences is the Xcon cone, upgraded suspension, sandwiched leads, and coil change. As for tuning, you can tune the box in the 31/32hz range and be fine. oh ok. When would the new icons ship? Will still be a little bit yet. If you would like the prototype version, specify it in your order. ` are the T/S parameters on the prototype the same as the current icon? And would the prototype be the same price and have the same warranty? As there have been a few different versions of the "prototype" so we have not pulled official specs. At the moment, as it is still not fully released yet, pricing has not changed yet, and yes, warranty stays.
