The Spawn family of BVR and Olson-style cabinets is free for non-commercial use (commercial use conditions are easily met). Feedback from builders will help us improve the designs, and drive future modifications. Thanks must be given in particular to Greg Monfort and Martin J. King for their advice, and MathCAD worksheets, without which these enclosures would not have come to fruition.




*Sadly, our friend Terry Cain died just before midnight on Sunday 10th December 2006 after a battle with both Lyme Disease and Lou Gerhig's Disease. He will be sadly missed by the DIY and the general audio community. He was always helpful, a great inspiration to others, and he designed and built many superb speakers. These double-mouth horns are dedicated to his memory.
