• Jasper Circle Jigs

Jasper Jigs are USA made and are the ideal tool for speaker builders as they aid users with a router to easily cut speaker holes. Precision is the key and they are ideal for flush mounting speakers. In addition woodworkers can use them for other applications that require circular cuts.

Cutting holes in speaker boxes has always been a time consuming job, often with less than perfect results - wrong size, uneven edges, much sanding required etc. Now we have the solution - Jasper Tools precision circle jigs make light work of cutting holes. You can even make a rebate to mount the driver flush with the wood panel!

Jasper Audio manufactures precision router jigs in the USA to high quality standards and accuracy. Jasper Tools have the first one pass circle jig that requires no trial cuts. No sanding will be required to get a precision circle cut-out every time. Hole cutting no longer needs to be difficult!
