I have a 690, a vintage Rockwell and a big plunge Freund. The 690 does dedicated speaker hole work with the Jasper. We plunged the bit for many years before somebody invented the plunge router. The puin that comes with the jasper is longer than 3/4" so you can posiiton it in the hole and then push down on the router. This is why I use a downshear bit. If I could only have one it would be the 690, no question. Just be careful.
