We have been working on this for the past year, and it is finally ready. The prototype is meeting expectations perfectly. Starting with our famous low distortion high power TSADv1 Neodymium 4.5" voice coil motor and our 2400 watt RMS, 4800 watts peak, DSP controlled amplifier we have designed a 15" driver with over 3" peak to peak travel with low and linear inductance. An incredibly stiff and strong Kevlar/paper fiber cone and a tough rubber surround are used to take the pressures developed inside the horn with ease. Then on to the enclosure design, it is a front loaded horn 9 feet in length featuring a symmetrical throat chamber layout for even and efficient loading of the driver cone. With a -3db point of 35hz, in room response will get to 20-30hz. Peak output is 140db, @1m half space. As is our usual the enclosure is made with 100% Baltic birch. Overall size is 22"x22"x60" and weighs 140lbs.
