Active Projects
| Name | Description | Images | ||
|---|---|---|---|---|
| 4 foot Floorstanding Loudspeakers | Hi-Fi Loudspeakers based around a 12" bass driver and a 5" Tweeter. | In Progress | ||
| Rotary Subwoofer | A complete redesign of the Thigpen TRW-17. A variable-pitch fan will create sound by oscillating the blade angle at the desired frequency. This will permit the speaker to produce sub-audible frequencies at very high sound pressure levels compared to a conventional cone driver. Amplification will be via an existing Quad 44 monoblock valve amplifier. |
