I'll bet $1 that more people DIY speakers without a router than those who do use one
>>>>>>>>>>>>>>>>>> I am one of them...instead of buying a cheap jigsaw and a cheap router (not that I have not already been thru a few of each though)
I invested in a good Bosch jigsaw and it does everything I need
although I probably will have to buy another router this time.
If I ever had any advice for a DIYer its invest in good tools right off the bat.
