Barney----Still got a couple old hot rods, (sold two)....just no time to cruise!..
Jay---regarding the 4" port. Nothing "magical" to be sure. Jim and I have learned a couple little "tweaks" over the years that help a bit. But the new DSP frontend on our amplifiers is really the key here. The control we have now is amazing. I definitely wouldn't call it high pass filtering...but there is some minor signal manipulation. As always, it's just an overall balancing act.
Saturn94---Jim and I don't like to hype up "vaporware". We are working on a few different things(who isn't?) that are quite interesting. Once we are close to shipping (within a month for example) we'll tend to be more talkative on the specifics.
