The first test session with both was so good, lots and lots of undistorted bass leaving the mighty box.. Effortless and natural as many said before about your hybrid designs! It hammers every note down to the point where it feels like big slaps of air hitting you. If one dares to stick their head close it literally is breathtaking. Seriously. Much respect and thanks again to you Ricci for taking your time to design this subwoofer and for making it available to the DIY community! Please PM me with your paypal/banking details so we can send a donation your way!! Outdoor measurements couldn't be taken yet due to rain but I can try to get some 1Watt/1m/nearfield indoor responses if wanted. If someone wants to have a listen please don't hesitate to ask about my whereabouts in Germany.. Cheers, Nathan

Looks like this Ora company is doing a lot of work with graphene for cones and domes. I think we are far more likely to see small multimedia transducers using this before we start seeing 18" graphene composite cones. The name of the game with this stuff is a very thin layer to beef up a thicker carrier material or perhaps a multi layer foam core sandwich. I do own a fishing pole with some graphene in the blank.

Good stuff Nathan! Even with subs, its all about sensitivity... as you can now hear! Now get that thing painted.
