Agreed Freddy,I myself am not so much a fan of efficiency for the sake of efficiency, but the amplifier options, huge headroom, and mostly the reduced power compression are my main reasons for the interest. At the same time, my subwoofer design is rather compact for what it does.
The higher efficiency versions of the TD-15 woofer will prove very interesting indeed, and I'll be looking at the benefits/compromises between those for my design.
It's hard to realize how much heat is really getting dissipated with those 200W delivered. If we go back to the actual efficiency (no. in %) of the woofer itself, the percentage of power which isn't turned into acoustic output HAS to go somewhere. Most all of that power turns into heat. So, the more efficient versions of the TD15 will have less heat to dissipate with the same input, and obviously will also have more acoustic output for that same power input... Things get quite scarry, especially given the physical throw these drivers are capable of :-).
I'll post the T/S specs this afternoon.
