Description
With the increasing popularity lately of the classic vintage styled large box format loudspeakers from manufacturers such as Wharfedale, KLH, PSB and others, I have set out to design and build my own version.
It is a typical 3-way design with a tweeter, 4 inch mid-range and 8 inch woofer. The dimensions are roughly 600mm high, 300mm wide, and just short of 400mm deep.
The result is a high-end loudspeaker that has loads of detail and balance across the frequency range. Despite the wide baffle, the sound stage and imaging is still top notch, and when positioned right, they will still disappear into the background.
This is a high-end loudspeaker, and building the cabinet will require some intermediate to advanced woodworking skills.
When following this build plan, the end result should give you speakers that will have the following approximate specifications:
Drive Units:
- Tweeter: Fountek NeoCD3.0 Ribbon Tweeter
