Looks like the HD15, from Rog Mogale, his website is; www.speakerplans.com
He used to work for Turbosound, now has his own brand called VOID.

Roger is a regular poster on hear.... He never worked for turbo, but is the owner of Void.... The former guys at turbo was tony Andrews and john newsham, now owners of function one.
