Pete Riggle is a graduate Mechanical Engineer (University of Washington, 1962) with a long career in mechanical and electrical design and analysis working on devices as diverse as artificial heart power sources, Stirling engines, linear electric motors, conversion of solar power to electric power, and audio components. Around 1980 we had a fling at loudspeaker design, manufacturing, and direct sales as Riggle Acoustics.
 

Pete’s interest in audio goes back to crystal radios.

Pete’s first real component audio system, around 1959, was a pair of Japanese full range drivers in sealed boxes, driven by an EICO HF-81 push-pull integrated full function tube amp. The signal source was a Bogen rim-drive turntable with a Shure cartridge.

A lot of ground has been covered in the intervening years.

Pete’s latest audio system is a pair of George Wright 2A3 mono-block single ended amplifiers driving a pair of very large all-horn loudspeakers ( we call them the PoBoys) in a dedicated listening room (we call it the Garden of Earthly Delights). The results are pretty wonderful. Indeed I have found that there is a light at the end of the tunnel.

Pete is blessed by a plethora of good audiophile friends/companions, with good ears, who tend to keep him honest.

Pete is always happy to answer any question, or kick around any idea posed by a customer, potential customer, or audio enthusiast. Pete normally limits his answers to those things about which he has direct experience.
